INTRODUCTION
WHAT IS THE SOT-223-5 VOLTAGE REGULATOR EVALUATION BOARD?
The SOT-223-5 Voltage Regulator Evaluation Board is designed to provide functional
evaluation of Microchip Voltage Regulators that utilize the SOT223-5 package and the
following device pinout:
The SOT-223-5 Voltage Regulator Evaluation Board does not come with a voltage
regulator soldered onto the board. This allows the users to attach the voltage regulator
of their choosing to the board and perform quiescent current, ground current, PSRR,
and other desired tests.
The SOT-223-5 Voltage Regulator Evaluation Board is based upon a modulare concept
that 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 SOT-223-5 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 SOT-223-5 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, C
populated with a 1 µF, 50V, XR7 ceramic capacitor.
Pin 1 = SHDN
Pin 2 = V
Pin 3 = GND
Pin 4 = V
Pin 5 = PWRGD / ADJ
