Package

The TPS76801QDR is a low-dropout voltage regulator by Texas Instruments, available in an 8-pin SOIC (Small Outline Integrated Circuit) package.

Pinout

The TPS76801QDR is a low-dropout linear voltage regulator from Texas Instruments. It typically comes in an 8-pin SOIC (Small Outline Integrated Circuit) package. Here's a brief overview of its pin functions:
1. IN: Input voltage supply.
2. GND: Ground connection.
3. OUT: Regulated output voltage.
4. FB (Feedback): Used to set the output voltage by connecting a resistor divider between the output and ground.
5. EN (Enable): Enables the regulator when high; when low, the regulator is in shutdown mode.
6. NC (No Connect): Not internally connected but should be isolated or connected to ground for mechanical stability.
7. NC: Another no-connect pin.
8. SS (Soft Start): Allows for programming the startup time by connecting a capacitor to ground.
The TPS76801 is designed for applications requiring a low dropout voltage and offers features like fast transient response, low quiescent current, and overcurrent protection.
