The LP2992AILD-3.3/NOPB is a 3.3V fixed output Linear Regulator designed to provide ultralow-dropout (LDO) and low noise in battery-powered applications. Using an optimized vertically integrated PNP (VIP) process, the device delivers unequaled performance in all specifications critical to battery-powered designs. Dropout voltage - typically 450mV at 250mA load and 5mV at 1mA load. Ground pin current - typically 1500µA at 250mA load and 75µA at 1mA load. Enhanced stability - the device is stable with output capacitor equivalent series resistance (ESR) as low as 5mR which allows the use of ceramic capacitors on the output. Sleep mode - less than 1µA quiescent current when ON/OFF pin is pulled low. Low noise - by adding a 10nF bypass capacitor, output noise can be reduced to 30µV (typical).
