DISCRETE SEMICONDUCTORS DATA SHEET k, halfpage MBD127 PSSI2021SAY Constant current source Product specification 2001 May 07 Philips Semiconductors Product specification Constant current source Features - One chip constant current source - Reduced number of ponents 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...
