Pinout
The TPS79930DDCT is a low-dropout (LDO) voltage regulator from Texas Instruments. It comes in a 5-pin SOT-23 package. The pin functions for this device are typically as follows:
1. IN: Input voltage supply. This is where the unregulated supply voltage is connected.
2. GND: Ground connection. This is the common ground for the input and output voltages.
3. EN: Enable pin. This pin turns the regulator on or off. A high signal enables the regulator, while a low signal disables it.
4. NR/FB: Noise Reduction/Feedback pin. This pin is used for noise reduction and can be connected to a capacitor to reduce output noise. In adjustable versions, it serves as a feedback pin.
5. OUT: Regulated output voltage. This is where the regulated voltage is outputted, set at 3.0V for this specific variant (TPS79930).
Note: Always refer to the official datasheet for detailed specifications and applications.
