LP2985
LP2985 is Micropower 150 mA Low-Noise Ultra Low-Dropout Regulator manufactured by National Semiconductor.
Description
The LP2985 is a 150 m A, fixed-output voltage regulator designed to provide ultra low-dropout and low noise in battery powered applications.
Using an optimized VIP™ (Vertically Integrated PNP) process, the LP2985 delivers unequalled performance in all specifications critical to battery-powered designs:
Dropout Voltage: Typically 300 m V @ 150 m A load, and 7 m V @ 1 m A load.
Ground Pin Current: Typically 850 µA @ 150 m A load, and 75 µA @ 1 m A load.
Enhanced Stability: The LP2985 is stable with output capacitor ESR as low as 5 mΩ, which allows the use of ceramic capacitors on the output.
Sleep Mode: Less than 1 µA quiescent current when ON/OFF pin is pulled low.
Smallest Possible Size: SOT-23 and micro SMD packages use absolute minimum board space.
Precision Output: 1%...
