3.3V LDO voltage regulator capable of delivering 400mA in a SOT-23-5 package

TPS73633DBVR General Description

TPS73633DBVR, a standout member of the TPS736xx family, redefines linear voltage regulation with its innovative NMOS pass element in a voltage-follower configuration. This groundbreaking topology ensures stability with low ESR output capacitors and even facilitates operation without a capacitor. The regulator's high reverse blockage and consistent ground pin current across all output current values make it a reliable choice for a wide range of applications

Key Features

  • TPS73633DBVR is a low-dropout voltage regulator with a fixed output voltage of 3.3V
  • It has a very low dropout voltage of only 120mV at 400mA load current
  • It has very high PSRR and low noise, making it ideal for noise-sensitive applications
  • It has thermal shutdown and overcurrent protection features for added reliability
  • It is available in a small SOT-23 package for space-constrained applications
  • Application

    • Stable power source
    • Efficient voltage control
    • Noise reduction technology
