OUT2 GETTING STARTED The TC1303 DFN Adjustable Output Demo Board is fully assembled and tested for evaluating the TC1303C device. The board requires the use of an external input volt- age source of (2.7V to 5.5V) and maximum external load of 500 mA for buck regulator output and 300 mA for LDO regulator output. - Page 12 TC1303 DFN Adjustable Output Demo Board User’s Guide 4. The power-good output signal is available on the test point TP5 (PG). 5. The switch S1, position 1 and position 2 are used to determine the SHDN1 and SHDN2 modes for the TC1303C device.
- Page 13 2.7V to 5.5V and checking the output voltage, the line regulation can be calculated. The best way to evaluate the TC1303 DFN Adjustable Output Demo Board is to dig into the circuit. Measure voltages and currents with a DVM and probe the board with an oscilloscope.
