EMP8737 Datasheet | Elite Semiconductor Microelectronics Technology

ESMT/EMP CMOS Linear Regulator General Description The EMP8737 Features ultra-high power supply rejection ratio, low output voltage noise, low dropout voltage, low quiescent current and fast transient response. It guarantees delivery of 300m A output current for VIN=2.2V ~ 5.5V and supports preset output voltages ranging from 0.8V to 4.5V with 0.05V increment. It also guarantees delivery of 100m A output current for VIN range lower from 1.75V ~ 2.1V. Based on its low quiescent current consumption and its less than 1μA shutdown mode of logical operation, the EMP8737 is ideal for battery-powered applications. The high power supply rejection ratio of the EMP8737 holds well for low input voltages typically encountered in battery-operated systems. The regulator is stable with small ceramic capacitive loads (1µF typical). The EMP8737 is Available in miniature SOT-23-5 package.
