    FEATURES

• One chip constant current source

• Reduced number of components and board space.

APPLICATIONS

• Especially suitable for space reduction in, for example,

LED driving circuits or active bias controlling.

DESCRIPTION

Resistor equipped PNP transistor with two diodes on one

chip in a plastic SC-88A package. Built-in bias resistor and

two diodes allow operation as constant current source.

The stabilized current can be adjusted between 15 µA and

50 mA by connection of external resistors between

pins 4 and 5.
