Overview
ESMT/EMP Preliminary EMP8021 600mA CMOS Linear Regulator General Description The EMP8021 low-dropout (LDO) CMOS linear regulators feature low output voltage noise (63µV), low quiescent current (50µA), and fast transient response.
It Applications g g g g g g Wireless handsets PCMCIA cards DSP core power Hand-held instruments Battery-powered systems Portable information appliances guarantees delivery of 600mA output current, and supports preset output voltages ranging from 0.
8V to 4.
75V with 0.
05V increment.
The EMP8021 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 regulator is stable with small ceramic capacitive loads (2.
2µF typical).
