Pinout
1. Pin 1 (SHDN): Shutdown pin. A high input to this pin enables the regulator, while a low input disables it.
2. Pin 2 (GND): Ground pin. It is the reference point for all voltages in the IC.
3. Pin 3 (OUT): Regulated output voltage pin. It provides the output voltage to the load.
4. Pin 4 (OUT): Another regulated output voltage pin, often internally connected to Pin 3.
5. Pin 5 (SENSE): Sense pin. It allows remote sensing of the output voltage for improved regulation.
6. Pin 6 (FB): Feedback pin. Used to set the output voltage by connecting to an external resistor divider.
7. Pin 7 (IN): Input voltage pin. This is where the unregulated input voltage is supplied.
8. Pin 8 (BYPASS): Bypass pin. It allows for connecting a capacitor to reduce output noise.
The LT1763 is known for its low noise and low dropout voltage characteristics, making it suitable for battery-powered applications.
