Pinout
Here's a brief overview of its pin functions:
1. VIN: Input voltage supply pin where the input voltage is applied.
2. GND: Ground connection pin.
3. SHDN (Shutdown): This pin can be used to enable or disable the regulator. Pulling it low shuts down the device, reducing the quiescent current to a negligible level.
4. VOUT: Output voltage pin where the regulated 5V output is available.
5. NC (No Connect): Not internally connected, typically used for mechanical stability in PCB layout.
The LT1761 series is designed for low quiescent current, making it suitable for battery-operated devices. It also features thermal protection and short-circuit current protection.
