CMOS LDO Regulators for Portable Equipments 1ch 150mA CMOS LDO Regulators BH□□PB1WHFV Series No.11020EBT05 ●Description The BH□□PB1WHFV regulator series can respond to changes in output current by switching to a state in which regulator characteristics are ideal. The regulators cut power consumption by lowering their own current consumption to approximately 2 A when the application is operating in the standby state. During normal-current operation it will automatically switch to high-speed operating mode. The IC's soft start function reduce the rush current that flows to the output capacitors during startup. The HVSOF5 package, which features excellent heat dissipation, contributes to space-saving application designs. ●Features 1) Automatic switching between low-consumption and high-speed modes 2) Built-in rush current prevention circuit 3) Low-voltage 1.7 V operation 4) High accuracy output voltage: ± 1% 5) Circuit current during low-consumption operation: 2 A 6) Stable with a ceramic capacitor (0.47 µF) 7) Built-in temperature and overcurrent protection circuits 8) Built-in output discharge during standby operation function 9) Ultra-small HVSOF5 power package ●Applications Battery-driven portable devices, etc. ●Product lineup 150 mA BH□□PB1WHFV Series Product name 1.2 1.5 1.8 2.5 2.8 2.9 3.0 3.1 3.3 Package BH□□PB1WHFV √ √ √ √ √ √ √ √ √ HVSOF5 Model name: BH□□PB1W□ a b Symbol Description Output voltage specification □□ Output voltage (V) □□ Output voltage (V) 12 1.2 V (Typ.) 29 2.9 V (Typ.) 15 1.5 V (Typ.) 30 3.0 V (Typ.) a 18 1.8 V (Typ.) 31 3.1 V (Typ.) 25 2.5 V (Typ.) 33 3.3 V (Typ.) 28 2.8 V (Typ.) b Package HFV: HVSOF5 www.rohm.com 1/10 2011.01 - Rev.B © 2011 ROHM Co., Ltd.

BH□□PB1WHFV Series Technical Note ●Input Output capacitors It is recommended to insert bypass capacitors between input and GND pins, positioning them as close to the pins as possible. These capacitors will be used when the power supply impedance increases or when long wiring paths are used, so they should be checked once the IC has been mounted. Ceramic capacitors generally have temperature and DC bias characteristics. When selecting ceramic capacitors, use X5R or X7R, or better models that offer good temperature and DC bias characteristics and high tolerant voltages.

The input capacitor reduces the output impedance of the voltage supply source connected to the VCC. The higher value the output capacitor goes the more stable the whole operation becomes. This leads to high load transient response. Please confirm the whole operation on actual application board. Generally, ceramic capacitor has wide range of tolerance, temperature coefficient, and DC bias characteristic. And also its value goes lower as time progresses. Please choose ceramic capacitors after obtaining more detailed data by asking capacitor makers.

BH□□PB1WHFV Series Technical Note ●Notes for use 1. Absolute maximum ratings An excess in the absolute maximum ratings, such as supply voltage, temperature range of operating conditions, etc., can break down the devices, thus making impossible to identify breaking mode, such as a short circuit or an open circuit. If any over rated values will expect to exceed the absolute maximum ratings, consider adding circuit protection devices, such as fuses. 2. Thermal design Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating conditions. 3. Inter-pin shorts and mounting errors Use caution when positioning the IC for mounting on printed circuit boards. The IC may be damaged if there is any connection error or if pins are shorted together. 4. Thermal shutdown circuit (TSD) The IC incorporates a built-in thermal shutdown circuit (TSD circuit). The thermal shutdown circuit is designed only to shut the IC off to prevent runaway thermal operation. It is not designed to protect the IC or guarantee its operation. Do not continue to use the IC after operating this circuit or use the IC in an environment where the operation of this circuit is assumed. 5. Ground wiring patterns The power supply and ground lines must be as short and thick as possible to reduce line impedance. Fluctuating voltage on the power ground line may damage the device. 6. Overcurrent protection circuit The IC incorporates a built-in overcurrent protection circuit that operates according to the output current capacity. This circuit serves to protect the IC from damage when the load is shorted. The protection circuit is designed to limit current flow by not latching in the event of a large and instantaneous current flow originating from a large capacitor or other component. These protection circuits are effective in preventing damage due to sudden and unexpected accidents. However, the IC should not be used in applications characterized by the continuous operation or transitioning of the protection circuits. At the time of thermal designing, keep in mind that the current capability has negative characteristics to temperatures. 7. Actions in strong electromagnetic field Use caution when using the IC in the presence of a strong electromagnetic field as doing so may cause the IC to malfunction. 8. Back current In applications where the IC may be exposed to back current flow, it is recommended to create a path to dissipate this current by inserting a bypass diode between the VIN and VOUT pins. Back current VIN OUT STBY GND Fig.32 Example Bypass Diode Connection 9. I/O voltage difference Using the IC in automatic switching mode when the I/O voltage differential becomes saturated (VIN - VOUT < 150 mV) may result in a large output noise level. If the noise level becomes problematic, use the IC with the SEL pin in the high state when the voltage differential is saturated. 10. GND Voltage The potential of GND pin must be minimum potential in all operating conditions. www.rohm.com 8/10 2011.01 - Rev.B © 2011 ROHM Co., Ltd. All rights reserved.

BH□□PB1WHFV Series Technical Note 11. Preventing Rush Current By attaching the Rss and Css time constants to the STBY pin, sudden rises in the regulator output voltage can be prevented, dampening the flow of rush current to the output capacitors. The larger the time constant used, the greater the resulting reduction. However, large time constants also result in longer startup times, so the constant should be selected after considering the conditions in which the IC is to be used. 100 Rss = 10 k IO = no load Trise [sec]10 間me 起動時Startup ti1.0 m 100  0.01  0.1  1.0  Slow sFtarret qcuaepnaccyit af[nHcze] Css (F) Fig.33 VOUT Startup Time vs CSS Capacitance (Reference) 12. Regarding input Pin of the IC (Fig.34) This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them isolated. P-N junctions are formed at the intersection of these P layers with the N layers of other elements, creating a parasitic diode or transistor. For example, the relation between each potential is as follows: When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode. When GND > Pin B, the P-N junction operates as a parasitic transistor. Parasitic diodes can occur inevitable in the structure of the IC. The operation of parasitic diodes can result in mutual interference among circuits, operational faults, or physical damage. Accordingly, methods by which parasitic diodes operate, such as applying a voltage that is lower than the GND (P substrate) voltage to an input pin, should not be used.
