Overview
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.
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 EMP8020 holds well for low input voltages typically encountered in battery operated systems.
The regulator is stable with small ceramic capacitive loads (2.
2µF typical).
