TPS75105 - Two-Bank LED Driver

Download the TPS75105 datasheet PDF. This datasheet also covers the TPS75100 variant, as both devices belong to the same two-bank led driver family and are provided as variant models within a single manufacturer datasheet.

General Description

The TPS7510x linear low dropout (LDO) matching LED current source is optimized for low-power keypad and navigation pad LED backlighting applications.

The device provides a constant current to up to four unmatched LEDs organized in two banks of two LEDs each in a common-cathode topology.

Key Features

  • 1 Regulated Output Current with 2% LED-to-LED Matching.
  • Drives Up to Four LEDs at 25 mA Each in a Common Cathode Topology.
  • 28-mV Typical Dropout Voltage Extends Usable Supply Range in Li-Ion Battery.
