Pinout
The LP2980IM5X-ADJ is a low-dropout (LDO) voltage regulator with adjustable output. It comes in a SOT-23-5 package, which means it has 5 pins. Here are the functions of each pin:
1. VIN: Input voltage pin. This is where the input voltage is supplied to the regulator.
2. GND: Ground pin. This serves as the reference point for the input and output voltages.
3. VOUT: Output voltage pin. This is where the regulated voltage is output.
4. FB (Feedback): This pin is used to set the output voltage by connecting it to a resistor divider network, which feeds back a portion of the output voltage to the regulator.
5. SHDN (Shutdown): An active-low pin used to enable or disable the regulator. Pulling this pin low will disable the output.
The LP2980IM5X-ADJ is used for applications where a stable and adjustable output voltage is necessary, with a low dropout voltage for efficient operation.
