A Product Line of Diodes Incorporated ZLDO1117 Application Information The ZLDO1117 family of quasi-LDO regulators is easy to use. They are protected against short circuit and thermal overloads. (see block diagram). Thermal protection circuitry will shut down the regulator should the junction temperature exceed +150°C at the sense point. The ZLDO1117 is pin compatible with similar ‘1117 regulators and offers extended temperature range and improved regulation specifications. Operation The ZLDO1117 develops a 1.25V reference voltage between the output and the adjust terminal (see block diagram). By placing a resistor between these two terminals, a constant current is caused to flow through R1 and down through R2. For fixed output variants Resistors R1 and R2 are internal. Stability The ZLDO1117 requires an output capacitor as part of the device frequency compensation. As part of its improved performance over industry standard 1117 the ZLDO1117 is suitable for use with MLCC (Multi Layer Ceramic Chip) capacitors. A minimum of 4.7µF ceramic X7R, 4.7µF tantalum, or 47 µF of aluminum electrolytic is required. The ESR of the output capacitor should be less than 0.5Ω. Surface mount tantalum capacitors, which have very low ESR, are available from several manufacturers. When using MLCC capacitors avoid the use of Y5V dielectrics. Load Regulation For improved load regulation the ZLDO1117-ADJ should have the upper feedback resistor, R, connected as close as possible to V and the 1 OUT lower resistor, R2, connected as close as possible to the load GND return. This helps reduce any parasitic resistance in series with the load. Thermal Considerations ZLDO1117 series regulators have internal thermal limiting circuitry designed to protect the device during overload conditions. For continuous normal load conditions however, the maximum junction temperature rating of +125°C must not be exceeded. It is important to give careful consideration to all sources of thermal resistance from junction to ambient. For the SOT223-3L and TO252-3L packages, which are designed to be surface mounted, additional heat sources mounted near the device must also be considered. Heat sinking is accomplished using the heat spreading capability of the PCB and its copper traces. The θ (junction to tab)of the TO252-3L and SOT223-3L are JC +12°C/W and +16°C/W respectively. Thermal resistances from tab to ambient can be as low as +30°C/W. The total thermal resistance from junction to ambient can be as low as +42 to +46°C/W. This requires a reasonable sized PCB with at least one layer of copper to spread the heat across the board and couple it into the surrounding air. Datasheet specifications using 2 oz copper and a 5mmx5mm pad with T = +27°C, no air flow yielded θ (junction to tab) of A JA +73°C/W and +107°C/W for TO252-3L and SOT223-3L respectively. The thermal resistance for each application will be affected by thermal interactions with other components on the board. Some experimentation will be necessary to determine the actual value. Ripple Rejection When using the ZLDO1117 adjustable device the adjust terminal can be bypassed to improve ripple rejection. When the adjust terminal is bypassed the required value of the output capacitor increases. The device will require an output capacitor of 22µF tantalum or 150µF aluminum electrolytic when the adjust pin is bypassed. Normally, capacitor values on the order of 100µF are used in the output of many regulators to ensure good load transient response with large load current changes. Output capacitance can be increased without limit and larger values of output capacitance further improve stability and transient response. The curves for Ripple Rejection were generated using an adjustable device with the adjust pin bypassed. These curves will hold true for all values of output voltage. For proper bypassing, and ripple rejection approaching the values shown, the impedance of the adjust pin capacitor, at the ripple frequency, should be < R1. R1 is normally in the range of 100Ω to 200Ω. The size of the required adjust pin capacitor is a function of the input ripple frequency. At 120Hz, with R1 = 100Ω, the adjust pin capacitor should be >13µF. At 10kHz only 0.16µF is needed. For fixed voltage devices, and adjustable devices without an adjust pin capacitor, the output ripple will increase as the ratio of the output voltage to the reference voltage (V /V ). For example, with the output voltage equal to 5V, the output ripple will be increased by the ratio of 5V/1.25V. OUT REF It will increase by a factor of four. Ripple rejection will be degraded by 12dB from the value shown on the curve. ZLDO1117 7 of 14 July 2012 Document number: DS32018 Rev. 6 - 2 www.diodes.com © Diodes Incorporated
