TI LP2992IM5-3.0/NOPB

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 vertically integrated PNP (VIP) process, the LP2992 delivers unequaled performance in all specifications critical to battery-powered designs: Dropout voltage: Typically 450 mV at 250-mA load, and 5 mV at 1-mA load. Ground pin current: Typically 1500 μA at 250-mA load, and 75 μA at 1-mA 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-nF 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.
