Pinout
The LP2980AIM5X-3.3 is a low-dropout (LDO) voltage regulator with a specific output voltage of 3.3V. It is typically housed in a 5-pin SOT-23 package. The pin functions are as follows:
1. VOUT (Pin 1): This is the output pin where the regulated 3.3V is provided.
2. GND (Pin 2): This pin is connected to the ground or zero voltage reference for the device.
3. SHUTDOWN (Pin 3): This pin is used to enable or disable the regulator. When it is high, the regulator is active; when low, the regulator is in shutdown mode, minimizing power consumption.
4. VIN (Pin 4): This is the input pin where the unregulated voltage is supplied.
5. BYPASS (Pin 5): This pin is used to connect an external capacitor, which can improve the output noise performance by filtering high-frequency noise.
The LP2980AIM5X-3.3 is designed for applications requiring a stable output voltage with low input-to-output voltage differential.
