AL5802LP4 - ADJUSTABLE CURRENT SINK LINEAR LED DRIVER
The AL5802LP4 combines a high-gain NPN transistor with a pre-biased 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 (1).
The internal high-gain transistor develops approximately 0.6V a
