ESMT/EMP
Preliminary
EMP8020
Fast Ultra High-PSRR, Low-Noise, Low-Dropout, 300mA CMOS Linear Regulator
General Description
The EMP8020 low-dropout (LDO) CMOS linear regulator features an ultra-high power supply rejection ratio (78dB at 1kHz), low output voltage noise (48µV), low dropout voltage, low quiescent current (50µA), and fast transient response. It guarantees a delivery of 300mA output current, and supports preset output voltages ranging from 0.8V to 4.75V with 0.05V increments.
Applications
Wireless handsets PCMCIA cards DSP core power Hand-held instruments Battery-powered systems Portable information appliances
Features
The EMP8020 is ideal for battery-powered applications because of its low quiescent current consumption and its 1nA shutdown mode.
