Pinout
1. Pin 1 (GND): Ground pin, connects to the negative side of the input supply.
2. Pin 2 (Output): The regulated output voltage pin, provides a fixed output voltage of 5.0V.
3. Pin 3 (Shutdown - SHUTDOWN): Active-low shutdown pin, used to disable or enable the regulator. When low, the regulator is off; when high or unconnected, the regulator is on.
4. Pin 4 (Input): Input voltage pin, where the unregulated input voltage is supplied.
5. Pin 5 (Bypass - BYPASS): Optional bypass pin, used to connect a capacitor to reduce noise and improve transient response.
The LP2980AIM5X-5.0 is designed for applications requiring a stable 5.0V output, with features like low noise, low dropout voltage, and low quiescent current, making it suitable for battery-powered devices and other portable electronics.
