Product Overview

The TPS74401EVM-118 is an evaluation module designed to help the user easily evaluate and test the operation and functionality of the TPS74401 LDO linear regulator. This regulator require a low power bias voltage, VBIAS, and a power input voltage, VIN. The TPS74401 is capable of providing output voltages down to 0.8V and have an integrated supervisory circuit with open drain output that goes to high impedance when the output voltage reaches regulation (power good or PG). The TPS74401 can provide up to 1.5A and 3.0A dc current, respectively, and have a SS pin which allows the user to set the output voltage's linear ramp rate. The goal of the evaluation module is to facilitate evaluation of the TPS74x01 ICs.
  • Supports input voltages as low as 0.9V with external bias supply due to ultra low dropout
  • Adjustable output (0.8V to 3.6V) up to 3A
  • Soft start time set by external capacitor
  • Stable with any or no output capacitor
  • 1% accuracy over line, load and temperature
  • Open drain power good (PG)
  • 5mm x 5mm x 1mm QFN package


Power Management, Signal Processing, Embedded Design & Development


It is important to operate this EVM within the input voltage of 5V and the output voltage of 3.3V. Exceeding the specified input range may cause unexpected operation or irreversible damage to the EVM.
