Pinout
The TPS73701DCQR is a fixed/adjustable low-dropout (LDO) linear voltage regulator from Texas Instruments. It comes in a 6-pin SOT-223 package. The main functions of its pins are:
1. IN: Input voltage pin. Connect the input voltage source to this pin.
2. GND: Ground pin. This is the ground reference for the device.
3. OUT: Output voltage pin. The regulated output voltage is provided through this pin.
4. NR/FB: Noise reduction or feedback pin. For adjustable output, connect this pin to a voltage divider network to set the desired output voltage. For fixed versions, use this pin to connect an external capacitor to reduce output noise.
5. EN: Enable pin. This pin is used to enable or disable the device. Pulling it high enables the regulator, while pulling it low disables it.
6. NC: No connection. Not internally connected and can be left unconnected on the PCB.
