FAQs

Q1: R2 and R5 seem to be designating the same resistor. Which resistor is R2 and which is R5?
A1: R2 is located in the lower left-hand corner and R5 is located in the upper right-hand corner. Below is a visual of this information. R2 and its placement are highlighted in red. While R5 and its placement are highlighted in black.

Q2: What does the pin PG mean?
A2: PG is Power Good, see the TPS7201 datasheet for more details. When this pin is high, the TPS7201 is regulating properly. If it is having trouble, the PG pin will go low. This is an open-collector pin, remove R4 if you don't want the pullup in your circuit.

Q3: I want to use a different lab voltage than the 3.3v on the board. What do I do?
A3: We've used the TPS7201 to allow changing the lab power voltage by only changing one resistor, R1. Refer to the TPS7201 documentation for more details. For your convenience, we've listed a few key values below:

Voltage Resistor Actual VCC
