1.1 Introduction

The TPS7N53EVM-138 evaluation module (EVM) is a linear regulator circuit that achieves low-noise (2.2μVRMS), ultra-low-dropout (95mV typ), and high PSRR in a small footprint. The EVM has the capability to operate over an input voltage range of 1.1V to 2.2V, providing a regulated output of 0.5V to 1.5V, with the capability to source 3A. The output voltage has a 1.5% setpoint accuracy and is adjusted by modifying the reference resistor value, permitting the user to customize the output voltage as needed.

The TPS7N53 low dropout (LDO) regulator used in the EVM has the following features:

  1. Input voltage range: 1.1V to 2.2V
  2. 1.5% accuracy over line, load, and temperature
  3. Low output voltage noise: 2.2μVRMS (100Hz to 100KHz)
  4. Low dropout: 95mV (typ) at 3A
  5. Adjustable output voltage range: 0.5V to 1.5V
  6. Adjustable soft-start inrush control
  7. Open-drain, power-good (PG) output
  8. Package: 3mm x 3mm, 16-pin WQFN
