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
guarantees delivery of 600mA output current, and
supports preset output voltages ranging from 0.8V to
4.75V with 0.05V increment.
Applications
g Wireless handsets
g PCMCIA cards
g DSP core power
g Hand-held instruments
g Battery-powered systems
g Portable information appliances
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).
Additional features include bandgap voltage
reference, constant current limiting and thermal
overload protection. The EMP8021 is available in
miniature 5-pin SOT-23-5 package.
