This combination provides high IN 7 14 OUT performance at a reasonable cost. NC 8 13 OUT Because the PMOS device behaves as a low-value GND/HSINK 9 12 GND/HSINK resistor, the dropout voltage is very low (typically 230 GND/HSINK 10 11 GND/HSINK mV at an output current of 1 A for the TPS76850) and NC − No internal connection is directly proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 85 µA over the full range of output current, 0 mA to 1 A). These two key specifications yield a significant improvement in operating life for battery-powered systems. This LDO family also features a sleep mode; applying a TTL high signal to EN (enable) shuts down the regulator, reducing the quiescent current to less than 1 µA at T = 25°C. J Power good (PG) is an active high output, which can be used to implement a power-on reset or a low-battery indicator. The TPS768xx is offered in 1.5-V, 1.8-V, 2.5-V, 2.7-V, 2.8-V, 3.0-V, 3.3-V, and 5.0-V fixed-voltage versions and in an adjustable version (programmable over the range of 1.2 V to 5.5 V). Output voltage tolerance is specified as a maximum of 2% over line, load, and temperature ranges. The TPS768xx family is available in a 20-pin PWP package.

Conventional LDO regulators use a pnp pass element, the base current of which is directly proportional to the load current through the regulator (I = I /β). The TPS768xx uses a PMOS transistor to pass current; because B C the gate of the PMOS is voltage driven, operating current is low and invariable over the full load range. Another pitfall associated with the pnp-pass element is its tendency to saturate when the device goes into dropout. The resulting drop in β forces an increase in I to maintain the load. During power up, this translates B to large start-up currents. Systems with limited supply current may fail to start up. In battery-powered systems, it means rapid battery discharge when the voltage decays below the minimum required for regulation. The TPS768xx quiescent current remains low even when the regulator drops out, eliminating both problems. The TPS768xx family also features a shutdown mode that places the output in the high-impedance state (essentially equal to the feedback-divider resistance) and reduces quiescent current to 2 µA. If the shutdown feature is not used, EN should be tied to ground. minimum load requirements The TPS768xx family is stable even at zero load; no minimum load is required for operation. FB - pin connection (adjustable version only) The FB pin is an input pin to sense the output voltage and close the loop for the adjustable option. The output voltage is sensed through a resistor divider network to close the loop as shown in Figure 27. Normally, this connection should be as short as possible; however, the connection can be made near a critical circuit to improve performance at that point. Internally, FB connects to a high-impedance wide-bandwidth amplifier and noise pickup feeds through to the regulator output. Routing the FB connection to minimize/avoid noise pickup is essential. external capacitor requirements An input capacitor is not usually required; however, a ceramic bypass capacitor (0.047 µF or larger) improves load transient response and noise rejection if the TPS768xx is located more than a few inches from the power supply. A higher-capacitance electrolytic capacitor may be necessary if large (hundreds of milliamps) load transients with fast rise times are anticipated. Like all low dropout regulators, the TPS768xx requires an output capacitor connected between OUT and GND to stabilize the internal control loop. The minimum recommended capacitance value is 10 µF and the ESR (equivalent series resistance) must be between 50 mΩ and 1.5 Ω. Capacitor values 10 µF or larger are acceptable, provided the ESR is less than 1.5 Ω. Solid tantalum electrolytic, aluminum electrolytic, and multilayer ceramic capacitors are all suitable, provided they meet the requirements described above. Most of the commercially available 10 µF surface-mount ceramic capacitors, including devices from Sprague and Kemet, meet the ESR requirements stated above.

The internal comparator monitors the output voltage: when the output drops to between 92% and 98% of its nominal regulated value, the PG output transistor turns on, taking the signal low. The open-drain output requires a pullup resistor. If not used, it can be left floating. PG can be used to drive power-on reset circuitry or used as a low-battery indicator. PG does not assert itself when the regulated output voltage falls out of the specified 2% tolerance, but instead reports an output voltage low, relative to its nominal regulated value. regulator protection The TPS768xx PMOS-pass transistor has a built-in back diode that conducts reverse currents when the input voltage drops below the output voltage (e.g., during power down). Current is conducted from the output to the input and is not internally limited. When extended reverse voltage is anticipated, external limiting may be appropriate. The TPS768xx also features internal current limiting and thermal protection. During normal operation, the TPS768xx limits output current to approximately 1.7 A. When current limiting engages, the output voltage scales back linearly until the overcurrent condition ends. While current limiting is designed to prevent gross device failure, care should be taken not to exceed the power dissipation ratings of the package. If the temperature of the device exceeds 150°C(typ), thermal-protection circuitry shuts it down. Once the device has cooled below 130°C(typ), regulator operation resumes. power dissipation and junction temperature Specified regulator operation is assured to a junction temperature of 125°C; the maximum junction temperature should be restricted to 125°C under normal operating conditions. This restriction limits the power dissipation the regulator can handle in any given application. To ensure the junction temperature is within acceptable limits, calculate the maximum allowable dissipation, P , and the actual dissipation, P , which must be less than D(max) D or equal to P . D(max) The maximum-power-dissipation limit is determined using the following equation: T max(cid:6)T P (cid:1) J A D(max) R(cid:1)JA Where: TJmax is the maximum allowable junction temperature. RθJA is the thermal resistance junction-to-ambient for the package, i.e., 172°C/W for the 8-terminal SOIC and 32.6°C/W for the 20-terminal PWP with no airflow. TA is the ambient temperature. The regulator dissipation is calculated using: (cid:2) (cid:4) P (cid:1) V (cid:6)V (cid:5)I D I O O Power dissipation resulting from quiescent current is negligible. Excessive power dissipation will trigger the thermal protection circuit. POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 17
