TPS7A37 - Low-Dropout Regulator

Description

The TPS7A37 family of linear low-dropout (LDO) voltage regulators uses an NMOS pass element in a voltage-follower configuration.

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

Features

  • 1 Stable with 1-μF or Larger Ceramic Output Capacitor.
  • Input Voltage Range: 2.2 V to 5.5 V.
  • Ultralow Dropout Voltage:.
  • 200-mV Maximum at 1 A.
  • Excellent Load Transient Response.
  • Even With Only 1-μF Output Capacitor.
  • NMOS Topology Delivers Low Reverse Leakage Current.
  • Excellent Accuracy:.
  • 0.23% Nominal Accuracy.
  • 1% Overall Accuracy Over Line, Over Load, and Over Temperature.
  • Less Than 20-nA typical IQ.
