TPS731 - 150-mA Low Dropout Regulator

General Description

The TPS731xx family of low-dropout (LDO) linear voltage regulators uses a new topology: an NMOS pass element in a voltage-follower configuration.

This topology is stable using output capacitors with low equivalent series resistance (ESR), and even allows operation without a capacitor.

Key Features

  • 1 Stable With or Without Capacitors of All Types.
  • Input Voltage Range of 1.7 V to 5.5 V.
  • Ultralow Dropout Voltage: 30 mV Typical (150-mA Load).
  • Excellent Load Transient Response.
  • With or Without Optional Output Capacitor.
  • New NMOS Topology Provides Low Reverse Leakage Current.
  • Low Noise: 30 μVRMS Typical (10 kHz to 100 kHz).
  • 0.5% Initial Accuracy.
  • 1% Overall Accuracy Over Line, Load, and Temperature.
  • Less Tha.
