EMP8130 Datasheet | Elite Semiconductor Microelectronics Technology

ESMT Ultra High-PSRR, Low-Noise, 300m A CMOS Linear Regulator General Description u DFN-4, SOT-23-3 and TDFN-6 package. The EMP8130 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 and supports preset output voltages ranging from 0.8V to 4.5V with 0.1V increment. Based on its low quiescent current consumption and its less than 1u A shutdown mode of logical operation, the EMP8130 is ideal for battery-powered applications. The high power supply rejection ratio of the EMP8130 holds well for low input voltages typically encountered in battery-operated systems. The regulator is stable with small ceramic capacitive loads . The EMP8130 offers current fold-back which throttles down the output current with a decrease in load resistance. The typical value at which current fold-back kicks in is 420m A; the typical value of the output short current limit value is 40m A.
