Product Overview

The TPS73733DCQ is a Single Output Low Dropout Linear Regulator with reverse current protection. This regulator uses a new topology an NMOS pass element in a voltage-follower configuration. This topology is stable using output capacitors with low ESR, allowing a wide variety of load configurations. Load transient response is excellent, even with a small 1µF ceramic output capacitor. The NMOS topology also allows very low dropout. The TPS73733 family uses an advanced BiCMOS process to yield high precision while delivering very low dropout voltages and low ground pin current. Current consumption, when not enabled, is less than 20nA and ideal for portable applications. This device is protected by thermal shutdown and foldback current limit.
  • Stable with no output capacitor or any value or type of capacitor
  • Ultralow dropout voltage (130mV typical at 1A)
  • Excellent load transient response even with only 1µF output capacitor
  • NMOS topology provides low reverse leakage current
  • 1% Initial accuracy
  • 3% Overall accuracy over line, load and temperature
  • <20nA Typical IQ in shutdown mode
  • Thermal shutdown and current limit for fault protection
  • Green product and no Sb/Br


Signal Processing, Portable Devices, Power Management


This device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
