TPS79942DDCT Datasheet High-psrr Low-dropout Linear Regulator

Manufacturer: Texas Instruments

Overview: TPS799 SBVS056L – JANUARY 2005 – REVISED FEBRUARY 2022 TPS799 200-mA, Low-Quiescent Current, Ultralow Noise, High-PSRR Low-Dropout Linear Regulator.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The TPS799 low-dropout (LDO), low-power linear regulator offers excellent ac performance with very low ground current.

High power-supply rejection ratio (PSRR), low noise, fast start-up, and excellent line and load transient response are provided while consuming a very low 40-μA (typical) ground current.

The TPS799 is stable with ceramic capacitors and uses an advanced BiCMOS fabrication process to yield a dropout voltage of typically 100 mV at a 200mA output.

Key Features

  • 200-mA low-dropout regulator with EN.
  • Multiple output voltage versions available:.
  • Fixed outputs of 1.2 V to 4.5 V.
  • Adjustable outputs from 1.20 V to 6.5 V.
  • Inrush current protection with EN toggle.
  • Low IQ: 40 μA.
  • High PSRR:.
  • 66 dB at 1 kHz.
  • 51 dB at 10 kHz.
  • Stable with a low-ESR, 2-μF typical output capacitance.
  • Excellent load and line transient response.
  • 2% overall accuracy (load, line,.
