LP2985 Micropower 150 mA Low-Noise Ultra Low-Dropout Regulator March 2000 LP2985 Micropower 150 mA Low-Noise Ultra Low-Dropout Regulator Designed for Use with Very Low ESR Output Capacitors General Description The LP2985 is a 150 mA, 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 mV @ 150 mA load, and 7 mV @ 1 mA load. Ground Pin Current: Typically 850 µA @ 150 mA load, and 75 µA @ 1 mA 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% toler.
