Chapter 2. Installation and Operation
2.1 INTRODUCTION
The SOT89-3 Voltage Regulator Evaluation Board is designed to be used to facilitate
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 SOT89-3 Voltage Regulator Evaluation Board kit comes with a 1 µF ceramic input
and output capacitor soldered to the board. The board has one unpopulated resistor
location that may be used for a load.
2.2 FEATURES
The SOT89-3 Voltage Regulator Evaluation Board has the following features:
• Input and Output headers for future connection to Line Step and Load Step
modules
• Ample testpoints to attach multimeters, power supplies, and loads.
• Jumper to select ground current measurement
• Jumper to connect output load resistor
• Jumper to connect input capacitor to circuit
• Jumper to select one of two device pinouts
2.3 GETTING STARTED
The SOT89-3 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 SOT89-3 Voltage Regulator
Evaluation Board shall now be described.
2.3.1 Device Pinout Selection (For All Tests)
For all tests, JP2 and JP5 must be set to select the desired device and footprint.
Jumpers U1 Footprint U2 Footprint
JP2 - connect pins 2-3 1-2
JP5 - connect pins 2-3 1-2
