General Description

The

Supertex

CL25

is

a

high

voltage,

temperature

compensated, constant current source. The device is trimmed

to provide a constant current of 25mA ± 10% at an input

voltage of 5-90V. No external components are required. The

device can be used as a two terminal constant current source

or constant current sink.

A typical application for the CL25 is to drive LEDs with a

constant current of 25mA. They can also be used in parallel

to provide higher currents such as 50mA, 75mA or 100mA.

The device is available in TO-92 and TO-243AA (SOT-89)

packaging.
