DESCRIPTION
The UTC LR1101 series are ultra-low quiescent current CMOS LDO (Low Dropout Voltage). Designed for battery-powered system, the low 4μA quiescent current makes it an ideal choice. The Range of the output voltage is from 1.5V ~ 5V with 0.1V per step. And the max output current is 100mA.
Wide range of available output fits most of applications. Built-in output current-limiting provide maximal protection against any fault conditions.
FEATURES
* 450mV typically dropout at 100mA
* Ultra-low quiescent current: 4μA
* Wide operating voltage ranges: 2V ~ 6V
* Thermal current limiting protection
* For stability only 1μF output capacitor is required
* High power supply rejection ratio

APPLICATION INFORMATION
Between VOUT and GND a 1μF (or larger) capacitor is recommended for stability. Without the capacitor the part may oscillate. When operating below -25℃ any type of capacitor can be used, but not Aluminum electrolytes. If there’s no limit the capacitance may be increased. Between VIN to GND a 1μF capacitor (or larger) should be placed.
