TPS51103 - INTEGRATED LDO

General Description

The TPS51103 integrates three LDOs.

The 5-V and 3.3-V LDOs are both rated at 100 mA and also include a glitch-free switch-over feature allowing for optimized battery life.

An additional 3.3-V LDO is designed to provide an always on power output for the real time clock (RTC).

Key Features

  • 1.
  • Wide Input Voltage Range: 4.5 V to 28 V.
  • 5-V/3.3-V, 100-mA, LDO Output.
  • Glitch Free Switch Over Circuit.
  • Always-On 3.3-V, 5-mA LDO Output for RTC.
  • 250 kHz Clock Output for Charge Pump.
  • Thermal Shutdown (Non-latch).
  • 10Ld QFN (DRC) Package.
