Pin Name

Pin Description

1

Sense

This pin is the positive side of the reference voltage for this device. With this pin it is

possible to Kelvin Sense the output voltage at the load.

2

Adjust / Ground

This pin is the negative side of the reference voltage for this device. Transient

response can be improved by adding a small bypass capacitor from the adjust pin to

ground.

3

Output

This pin is power output of the device.

4

Control

This pin is the supply pin for the control circuitry for the device. The current flow into

this pin will be about 1% of the output current. For the device to regulate, the voltage

at this pin must be 1.3V greater than the output voltage.

5

Power

This pin is the collector of the power transistor. The output load current is supplied

through this pin. The voltage at this pin must be 0.7V greater than the output voltage

for the device to regulate.
