Pinout
The TPS7A3001DGNT is a low-dropout (LDO) voltage regulator from Texas Instruments. It is designed to provide a stable output voltage with low noise and excellent transient response. The device comes in an 8-pin HVSSOP (DGN) package.
The pin functions are as follows:
1. IN: Input voltage pin where the unregulated input voltage is supplied.
2. GND: Ground pin, the return path for input and output currents.
3. NR/SS: Noise reduction/Soft-start pin, used to reduce output noise and control the startup time.
4. FB: Feedback pin, used to set the output voltage via an external resistor divider.
5. OUT: Output voltage pin, where the regulated voltage is output.
6. BP: Bypass pin, which can be connected to a capacitor to further reduce output noise.
7. EN: Enable pin, which turns the regulator on or off.
8. NC: No connection, typically not connected internally but should be left unconnected externally.
This LDO is suitable for applications requiring negative output voltages, high PSRR, and low dropout voltage over a wide input voltage range.
