Product Introduction

Overview

The TPS73601DRBT is a low-dropout (LDO) linear voltage regulator produced by Texas Instruments. This device is designed for high precision and low dropout voltage, making it suitable for a variety of applications, especially in portable and noise-sensitive environments. The TPS73601DRBT uses an advanced BiCMOS process and features an NMOS pass transistor in a voltage-follower configuration, ensuring stability with or without an output capacitor. It supports an input voltage range of 1.7V to 5.5V and can output voltages from 1.2V to 5.5V, with a maximum output current of 400mA.

  • Ultra-low dropout voltage of 75mV typical at 400mA output current.
  • Input voltage range from 1.7V to 5.5V and adjustable output voltage from 1.2V to 5.5V.
  • High precision and low noise output, making it suitable for powering VCOs and other noise-sensitive loads.
  • Integrated noise reduction (NR) pin for additional noise reduction with a noise reduction capacitor.
  • Protection features include thermal shutdown, foldback current limit, and reverse current protection.
  • Enable pin for controlling the regulator's operation.
  • Low quiescent current of less than 1µA when not enabled.

Applications

  • Portable electronic devices due to its low dropout voltage and low quiescent current.
  • Noise-sensitive applications such as powering VCOs (Voltage-Controlled Oscillators) and other precision analog circuits.
  • Systems requiring high precision and stability in voltage regulation.
  • Applications where the effective capacitance of the load is unknown or variable.
  • General-purpose voltage regulation in various electronic systems.
