TPS737 - 1-A Low-Dropout Regulator

General Description

The TPS737 linear low-dropout (LDO) voltage regulator uses an NMOS pass transistor in a voltagefollower configuration.

This topology is relatively insensitive to the output capacitor value and ESR, allowing for a wide variety of load configurations.

Key Features

  • Stable with 1-μF or larger ceramic output capacitor.
  • Input voltage range: 2.2 V to 5.5 V.
  • Ultra-low dropout voltage.
  • Legacy silicon: 130 mV typical at 1 A.
  • New silicon, M3 suffix: 122 mV typical at 1 A.
  • Excellent load transient response.
  • even with only 1-μF output capacitor.
  • NMOS topology delivers low reverse leakage current.
  • Initial accuracy: 1%.
  • Overall accuracy over line, load, and temperature.
  • L.
