Constant current source

Integrated solutions to save board space

Incorporating a resistor-equipped PNP transistor with two diodes on one chip, our dedicated constant current source device is housed in a SOT353 package. Reducing board space and component count, it provides stabilized output current of between 15 µA and 50 mA. AEC-Q101 qualified, the device is ideal in automotive and generic applications, as well as in active bias control for audio amplifiers.
