TO220-3/TO263-3 VOLTAGE REGULATOR
EVALUATION BOARD USER ’S GUIDE
Chapter 1. Product Overview
1.1
INTRODUCTION
The TO220-3 / TO263-3 Voltage Regulator Evaluation Board is designed to provide
functional evaluation of Microchip Voltage Regulators that utilize the TO220-3 and
TO263-3 package and the following device pinouts:
Pin Number
Pin 1
Pin 2
Pin 3
U1 footprint
V IN
GND
V OUT
The TO220-3 / TO263-3 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 TO220-3 / TO263-3 Voltage Regulator Evaluation Board is based upon a modular
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.
1.2
WHAT IS THE TO220-3/TO263-3 VOLTAGE REGULATOR EVALUATION
BOARD?
The TO220-3 / TO263-3 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.
1.2.1
Funtional Blocks
The TO220-3 / TO263-3 Voltage Regulator Evaluation Board can be broken up into
three functional blocks. These blocks are:
? Input Capacitance
? Ground Current Measurement
? Load Resistor
1.2.2
Input Capacitance
Jumper JP1 connects the input capacitance to the circuit. The input capacitor is
disconnected when performing Power Supply Ripple Rejection tests. By default, C 1 is
populated with a 1 μF, 50V, XR7 ceramic capacitor.
1.2.3
Ground Current Measurement
Jumper JP3 allows measurement of ground current. When a current meter is
connected to TP6 and TP7 and jumper JP3 is removed, the ground current of the
device may be measured.
