EMP8915

ESMT/EMP EMP891X Fast Ultra High-PSRR, Low-Noise, Low-Dropout, 150mA Micropower CMOS Linear Regulator General Description The EMP891X series is a family of CMOS linear regulators, which include EMP8915 and EMP8916, featuring SOT-25, SOT-26 and TDFN-6 packages, the EMP891X series are suitable for portable appliances. EMP products is RoHS compliant. ultra-high power supply rejection ratio, low output voltage noise, low dropout voltage, low quiescent current and fast transient response. EMP891X Features „ „ „ „ „ „ „ „ „ „ Miniature SOT-25, SOT-26 and TDFN-6 packages 150mA guaranteed output current 75dB typical PSRR at 1kHz (60dB typical at 10KHz) 30µV RMS output voltage noise (10Hz to 100kHz) 65mV typical dropout at 150mA 106µA typical quiescent current Less than 1μA typical shutdown mode Fast line and load transient response 80µs typical fast turn-on time 2.5V to 5.5V input range Stable with small ceramic output capacitors Over temperature and over current protection ±2% output voltage tolerance ±1% output voltage tolerance for Vout 1.5V guarantees delivery of 150mA output current, and supports preset 1.2V, 1.3V, 1.5V, 1.8V, 2.5V, 2.8V, 2.85V output voltage versions. Based on its low quiescent current consumption and its less than 1μA shutdown mode of logical operation, the EMP891X series are ideal for battery-powered applications. The ground current increases only slightly in dropout, further prolonging the battery life. EMP891X series provide fast turn-on by using ded...
