CS5208−1
8.0 A LDO 3−Pin Adjustable
Linear Regulator
The CS52081 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 TO220 package.

2. The minimum load current is the minimum current required to maintain regulation. Normally the current in the resistor divider used to set the
output voltage is selected to meet the minimum load current requirement.
3. This parameter is guaranteed by design and is not 100% production tested.
4. Dropout voltage is defined as the minimum input/output voltage differential required to maintain 1.5% regulation.
5. This parameter is guaranteed by design, but not parametrically tested in production. However, a 100% thermal shutdown functional test is
performed on each part.
