Texas Instruments LP2982AIM5X-5.0

Description
The LP2982 is a 50 mA, fixed-output voltage regulator designed for ultra-low dropout and lower noise in battery-powered applications. Using an optimized VIP (Vertically Integrated PNP) process, the LP2982 delivers exceptional performance in specifications critical to battery-powered designs:
Dropout Voltage: Typically 120 mV at 50 mA load, and 7 mV at 1 mA load
Ground Pin Current: Typically 375 μA at 50 mA load, and 80 μA at 1 mA load
Sleep Mode: Less than 1 μA quiescent current when the on/off pin is pulled low
Precision Output: 1.0% tolerance output voltages available (A grade)
