INTRODUCTION
FEATURES
GETTING STARTED
Chapter 2. Installation and Operation
The TO220-5 / TO263-5 Voltage Regulator Evaluation Board is designed to be used to
facilitate the evaluation of Microchip’s voltage regulators or to be used as a standalone
voltage regulator board. Jumpers have been placed on the board to facilitate testing of
specific voltage regulator parameters.
The TO220-5 / TO263-5 Voltage Regulator Evaluation Board kit comes with a 1 µF
ceramic input and output capacitor soldered to the board. The board has two
unpopulated resistor locations that may be used for loads.
The TO220-5 / TO263-5 Voltage Regulator Evaluation Board has the following
features:
• Input and Output headers for future connection to Line Step and Load Step
• Ample testpoints to attach multimeters, power supplies, and loads
• Jumper to select ground current measurement
• Jumpers to connect output load resistors
• Jumper to connect input capacitor to circuit
The TO220-5 / TO263-5 Voltage Regulator Evaluation Board is fully assembled and
tested. All that is required for operating is a user supplied voltage regulator and a
supply voltage source. Some of the tests that may be completed using the TO220-5 /
TO263-5 Voltage Regulator Evaluation Board shall now be described.
2.3.1
When measuring ground current, jumper JP3 should be removed, otherwise leave
jumper JP3 on. To measure ground current, perform the following steps:
1. Add desired load resistors to R5 and R6.
2. Remove jumpers JP3, JP4, and JP5.
3. Connect an Ampere Meter across testpoints TP6(+) and TP7(-). Select the
4. Connect a voltmeter across testpoints TP9(+) and TP10(-).
5. Add jumper JP1.
6. Apply source voltage to testpoints TP1(+) and TP2(-).
7. Verify the voltage across testpoints TP9 and TP10 is within the expected range
8. Read the Ground Current directly from the ampere meter connected to testpoints
