LP2992 Micropower 250 mA Low-Noise Ultra Low-Dropout Regulator in SOT-23 and LLP Packages June 2002 LP2992 Micropower 250 mA Low-Noise Ultra Low-Dropout Regulator in SOT-23 and LLP Packages Designed for Use with Very Low ESR Output Capacitors General Description The LP2992 is a 250 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 LP2992 delivers unequalled performance in all specifications critical to battery-powered designs: Dropout Voltage: Typically 450 mV @ 250 mA load, and 5 mV @ 1 mA load. Ground Pin Current: Typically 1500 µA @ 250 mA load, and 75 µA @ 1 mA load.
