EUP7987 Datasheet | Eutech Microelectronics

DESCRIPTION The EUP7987 low-noise, low-dropout, linear regulator operates from a 2.5V to 5.5V input and is guaranteed to deliver 300m A. The EUP7987 is stable with small 2.2µF ceramic capacitor. Its performance suits battery powered applications because of its shutdown mode (60 n A .. typ), low quiescent current (110µA typ), and LDO voltage (140m V typ). The low dropout voltage allows for more utilization of a battery’s available energy by operating closer to its end-of-life voltage. The EUP7987 is available in 1.8V, 2.5v, 2.8V, 3V, 3.3V, and adjustable versions.
