Using an optimized vertically integrated PNP (VIP) process, the LP2992 delivers unequaled performance in all specifications critical to battery-powered designs: - Dropout voltage: Typically 450 m V at 250-m A load, and 5 m V at 1-m A load. - Ground pin current: Typically 1500 µA at 250-m A load, and 75 µA at 1-m A load. - Enhanced stability: The LP2992 is stable with output capacitor equivalent series resistance (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 WSON packages use absolute minimum board space. - Precision output: 1% tolerance output voltages available (A grade). - Low noise: By adding a 10-n F bypass capacitor, output noise can be reduced to 30 µV (typical). - Multiple voltage options, from 1.5 V to 5 V, are available as standard products.
