EMP8966

ESMT/EMP EMP8966 Fast Ultra High-PSRR, Low-Noise, Low-Dropout, 600mA Micropower CMOS Linear Regulator General Description The EMP8966 low-dropout (LDO) CMOS linear regulators, feature ultra-high power supply rejection ratio (75dB at 1kHz), low output voltage noise (30µV), low dropout voltage (270mV), low quiescent current (110µA), and fast transient response. It guarantees delivery of 600mA output current, and supports adjustable (1.2V to 5.0V) output voltage versions. EMP products is RoHS compliant. for different applications. Features „ „ „ „ Miniature SOT-23-5, SOT-23-6and SOT-89-5 packages 600mA guaranteed output current 75dB typical PSRR at 1kHz 30µV RMS output voltage noise (10Hz to 100kHz) 270mV typical dropout at 600mA 110µA typical quiescent current 1nA 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 The EMP8966 is ideal for battery-powered applications by virtue of its low quiescent current consumption and its 1nA shutdown mode of logical operation. The regulator provides fast turn-on and start-up time by using dedicated circuitry to pre-charge an optional external bypass capacitor. This bypass capacitor is used to reduce the output voltage noise without adversely affecting the load transient response. The high power supply rejection ratio of the EMP8966 holds well for low input ...
