The TPS75103 is a low-dropout (LDO) linear LED driver designed to drive up to four LEDs in two independent banks. It operates from an input voltage range of 2.7V to 5.5V, making it suitable for single-cell Li-Ion battery applications. Each channel can provide up to 25mA of current with a typical quiescent current of 180µA. The device features a PWM interface for brightness control and is designed to eliminate the need for external current-sensing resistors by using internal current sinks.
