LP5951MF-1.8/NOPB

The LP5951MF-1.8/NOPB is a micro-power low-dropout CMOS Voltage Regulator designed to meet the requirements of portable battery-powered systems providing a regulated output voltage and low quiescent current. When switched to shutdown mode via a logic signal at the Enable (EN) pin, the power consumption is reduced to virtually zero. The LP5951 is designed to be stable with small 1µF ceramic capacitors. The device also features internal protection against short-circuit currents and overtemperature conditions. The device is available in fixed output voltages in the range of 1.3 to 3.7V.
