AL5802LP - LED DRIVER
The AL5802LP combines a high-gain NPN transistor with a prebiased NPN transistor to make a simple, small footprint LED driver.
Pin Assignments The LED current is set by an external resistor connected from REXT pin (2) to GND pin (3), and the internal high-gain transistor develops approximately 0.6
