CS5210−1
10 A LDO 3−Pin Adjustable
Linear Regulator
The CS5210−1 linear regulator provides 10 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
1.05 V at 10 A.
The regulator is protected against overload conditions with
overcurrent and thermal shutdown protection circuitry.
The regulator is available in a TO−220 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 2.0% 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.

Function
This pin is connected to the low side of the internally trimmed 2.0% bandgap reference
voltage and carries a bias current of about 70 μA. A resistor divider from Adj to VOUT and from
Adj to ground sets the output voltage. Also, transient response can be improved by adding a
small bypass capacitor from this pin to ground.
This pin is connected to the emitter of the power pass transistor and provides a regulated
voltage capable of sourcing 10 A of current.
This is the supply voltage for the regulator. For the device to regulate, this voltage should be
between 1.2 V and 1.40 V (depending on the output current) greater than the output voltage.
