Overview

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.

  • 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 - Legacy silicon: 3% - New silicon, M3 suffix: 1.5%
  • Less than 20 nA typical IQ in shutdown mode
  • Thermal shutdown and current limit for fault protection
  • Available in multiple output voltage versions: - Adjustable output: 1.20 V to 5.5 V - Custom outputs available using factory package-level programming
