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.

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.
