STMicroelectronics STCS1APHR SO Display Driver, 8 Pin, 3 → 5.5 V

The STCS1A is a BiCMOS constant current source designed to provide a precise constant current starting from a varying input voltage source. The main target is to replace discrete components solution for driving LEDs in low voltage applications such as 5 V, 12 V or 24 V giving benefits in terms of precision, integration and reliability.
The current is set with external resistor up to 1.5 A with a ± 10 % precision
