Overview

The TPS7A21 evaluation module (EVM) helps design engineers evaluate the operation and performance of the TPS7A21 linear regulator for use in their own circuit application. This EVM configuration contains a single low-noise, small-size, low-dropout (LDO)regulator for a wide range of applications.

The regulator is capable of delivering up to 500 mA to the load with low VIN to VOUT dropout voltage. For stability, use a minimum derated output capacitance of 400 nF (or larger) up to a maximum of 200 µF.

A high-performance load-transient circuit is included to improve the measurement capability of the LDO regulator.

Features
  • Very low quiescent current (IQ): 6.5 µA
  • Input voltage range: 2 V to 6 V
  • High power-supply rejection ration (PSRR): 95 dB at 1 kHz
  • Low output voltage noise: 7 μVRMS
  • Low dropout (LDO): 171 mV (max) at 500 mA (3.3-V VOUT)
  • Smart enable (EN) pulldown
