STMicroelectronics STCS05A
The STCS05A 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 0.5 A with a ± 10 % precision; a dedicated pin allows implementing PWM dimming.- Min Voltage : 4.5V
- Max Voltage : 40V
- Max Operating Temp : 125°C
- Min Operating Temp : -40°C
