SOT23-5 VOLTAGE REGULATOR
EVALUATION BOARD USER ’S GUIDE
Chapter 2. Installation and Operation
2.1
2.2
INTRODUCTION
The SOT23-5 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 jumpers may also be used to select pull-up and pull-
down voltage levels.
The SOT23-5 Voltage Regulator Evaluation Board kit comes with a 1 uF ceramic input
and output capacitor soldered to the board. A 10K resistor in series with the SHDN pin
is also populated on the board. The PWRGD/ADJ pin has a 69.8 k Ω resistor soldered
to the board. The board has three more unpopulated resistor locations that may be
used for loads and voltage adjustments. The board also has an unpopulated location
that may be used for bypass capacitance.
FEATURES
The SOT23-5 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 select load resistor
? Jumper to select shutdown pin input: V DD , GND, or use testpoint
? Jumper to connect input capacitor to circuit
? SMT0805 PCB footprints for user Power Good pull-up resistor
? SMT0805 PCB footprints for user Adjustable Voltage resistor divider
? SMT0805 PCB footprints for user Bypass Capacitor
