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.

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

• 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
