CS5208â1
8.0 A LDO 3âPin Adjustable
Linear Regulator
The CS5208â1 linear regulator provides 8.0 A at adjustable
voltages from 1.25 V to 4.5 V. This adjustable device requires two
external resistors to set the output voltage and provide the minimum
load current for proper regulation.
This regulator is intended for use as a post regulator and
microprocessor supply. The fast loop response and low dropout
voltage make this regulator ideal for applications where low voltage
operation and good transient response are important.
The circuit is designed to operate with dropout voltages as low as
1.0 V at 8.0 A.
The regulator is protected against overload conditions with
overcurrent and thermal shutdown protection circuitry.
The regulator is available in a TOâ220 package.
