SOT23-5 VOLTAGE REGULATOR
EVALUATION BOARD USER ’S GUIDE
Chapter 1. Product Overview
1.1
INTRODUCTION
The SOT23-5 Voltage Regulator Evaluation Board is designed to provide functional
evaluation of Microchip Voltage Regulators that utilize the SOT23-5 package and the
following device pinouts:

The SOT23-5 Voltage Regulator Evaluation Board does not come with a voltage
regulator soldered onto the board. This allows the user to attach the voltage regulator
of their choosing to the board and perform quiescent current, ground current, PSRR,
and other desired tests.
The SOT23-5 Voltage Regulator Evaluation Board is based upon a modulare concept
which will allow the user to plug in additional boards to increase the test capability of
the voltage regulator. Planned additional modulare plugin boards currently consist of
an Input Voltage Linestep Board, Output Voltage Loadstep Board, and several other
device packages.

WHAT IS THE SOT23-5 VOLTAGE REGULATOR EVALUATION BOARD?
The SOT23-5 Voltage Regulator Evaluation Board is designed to evaluate and test
voltage regulators. By soldering the desired device to the evaluation board, the user
can easily validate several parameters of the device.
