SOT223-3 VOLTAGE REGULATOR
EVALUATION BOARD USER ’S GUIDE
Chapter 1. Product Overview
1.1
1.2
INTRODUCTION
The SOT223-3 Voltage Regulator Evaluation Board is designed to provide functional
evaluation of Microchip Voltage Regulators that utilize the SOT223-3 package and the
following device pinout:
- Pin 1 = V IN
- Pin 2 = GND
- Pin 3 = V OUT
The SOT223-3 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 SOT223-3 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.
WHAT IS THE SOT223-3 VOLTAGE REGULATOR EVALUATION BOARD?
The SOT223-3 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
Funtional Blocks
The SOT223-3 Voltage Regulator Evaluation Board can be broken up into 3 functional
blocks. These blocks are as follows:
? Input Capacitance
? Ground Current Measurement
? Load Resistor
1.2.2
Input Capacitance
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.
1.2.3
Ground Current Measurement
Jumper JP3 allows measurement of ground current. When a current meter is
connected to TP6 and TP7 and jumper JP3 is removed, the ground current of the
device may be measured.
