TPS71921 - Low-Dropout Linear Regulators

Download the TPS71921 datasheet PDF. This datasheet also covers the TPS71812 variant, as both devices belong to the same low-dropout linear regulators family and are provided as variant models within a single manufacturer datasheet.

Description

The TPS718xx and TPS719xx families of low-dropout (LDO) regulators offer a high power-supply rejection ratio (PSRR), low noise, fast start-up, and excellent line and load transient responses while consuming a very low 90µA (typical) at no load ground current with both LDOs enabled.

Features

  • 1.
  • 23 Dual, 200mA High-Performance LDOs.
  • Low Total Quiescent Current: 90µA with Both LDOs Enabled.
  • Low Noise: 70µVRMS/V.
  • Active Output Pulldown (TPS719xx).
  • Independent Enables for Each LDO.
  • PSRR: 65dB at 1kHz, 45dB at 1MHz.
  • Available in Multiple Fixed-Output Voltage Combinations from 0.9V to 3.6V Using Innovative Factory EEPROM Programming.
  • Fast Start-Up Time: 160µs.
  • Over-Current, Over-Temperature and Under-Voltage P.
