Evaluation Module Overview
1 Evaluation Module Overview
1.1 Introduction
The TPS7N53EVM-138 evaluation module (EVM) is a linear regulator circuit that achieves low-noise
(2.2μV ), ultra-low-dropout (95mV typ), and high PSRR in a small footprint. The EVM has the capability
RMS
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

1.4 Device Information
The TPS7N53 is a low-noise (2.2 μVRMS), ultra-low dropout linear regulator (LDO) capable of sourcing 3A with
95mV of dropout (typ). The device is able to operate over an adjustable output voltage from 0.5V to 1.5V with a
single external resistor. The TPS7N53 LDO is available in a 16-pin WQFN package with 3mm × 3mm footprint.
