... The output voltages range from 1.5V to 5.0V in 100mV increments and 2% accuracy. The RT9167/A is designed for use with very low ESR capacitors. The output remains stable even with 1µF ceramic output capacitor. The RT9167/A uses and internal PMOS as the pass device, which does not cause extra GND current in heavy load and dropout conditions ...

... RT9167/A must be carefully selected for regulator stability and performance. Using a capacitor whose value is > 1µF on the RT9167/A input and the amount of capacitance can be increased without limit. The input capacitor must be located a distance of not more than 0.5" from the input pin of the IC and returned to a clean analog ground ...

... MOSFET pass transistor, the dropout voltage is a function of drain-to-source on-resistance [R DS(ON) Reverse Current Path The power transistor used in the RT9167/A has an value and inherent diode connected between the regulator input and output (see Fig.3). If the output is forced above the input by more than a diode-drop, this ...

... IC’s junction temperature cools by 10°C, resulting in a pulsed output during continuous thermal-overload conditions. Thermal-overloaded protection is designed V OUT to protect the RT9167/A in the event of fault conditions. Do not exceed the absolute maximum junction- temperature rating of T operation. The output can be shorted to ground for an indefinite amount of time without damaging the part by cooperation of current limit and thermal protection ...
