Page 11: Chapter 2. Installation And Operation
Jumpers have been placed on the board to ease the test of the specific voltage regulator parameters. The SOT23-3 Voltage Regulator Evaluation Board kit comes with a 1 μF ceramic input and output capacitor soldered to the board. The board has two unpopulated resistor locations that may be used for loads. - Page 12 SOT23-3 Voltage Regulator Evaluation Board User’s Guide 2.3.2 Ground Current and Quiescent Current When measuring ground current, jumper JP3 should be removed, otherwise leave jumper JP3 on. To measure ground current, perform the following steps: 1. Add the desired load resistor to R5.
- Page 13 Power Supply Rejection Ratio (PSRR) Power Supply Rejection Ratio tests are performed by removing the input capacitor jumper, JP1, and connecting an appropriate PSRR analyzer to the SOT23-3 Voltage Regulator Evaluation Board. The PSRR analyzer may then sweep the input voltage frequencies and record the corresponding output voltages.
