INTRODUCTION
WHAT IS THE TO220-5 / TO263-5 VOLTAGE REGULATOR EVALUATION
BOARD?
The TO220-5 / TO263-5 Voltage Regulator Evaluation Board is designed to provide
functional evaluation of Microchip Voltage Regulators that utilize the TO220-5 and
TO263-5 package and the following device pinouts:
The TO220-5 / TO263-5 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 TO220-5 / TO263-5 Voltage Regulator Evaluation Board is based upon a modulare
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.
The TO220-5 / TO263-5 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
The TO220-5 / TO263-5 Voltage Regulator Evaluation Board can be broken up into 6
functional blocks. The blocks are:
• Input Capacitance
• Shutdown Control
• Ground Current Measurement
• Voltage Adjust
• Power Good
• Load Resistor
1.2.2
Jumper JP1 connects the input capacitance to the circuit. The input capacitor is
disconnected when performing Power Supply Ripple Rejection tests. By default, C1 is
populated with a 1 µF, 50V, XR7 ceramic capacitor.
