Features
1. Output Voltage: Fixed at 5.0V.
2. Low Dropout Voltage: Typically around 50mV at light loads, making it ideal for battery-powered applications.
3. Low Quiescent Current: Consumes only about 120µA of ground current under load, with a reduced quiescent current of 1µA in standby mode.
4. High Accuracy: Provides a precise output voltage with a tolerance of ±1.5%.
5. Current Limiting: Built-in protection against overcurrent conditions.
6. Thermal Shutdown: Protects the device from damage due to overheating.
7. Reverse Battery Protection: Ensures no damage from incorrect battery insertion.
8. Small Size: Packaged in a 5-pin SOT-23, which is suitable for compact applications.
9. Input Range: Operates effectively with an input voltage range of 6V to 16V.
10. Output Capacitor: Stable operation with a small output capacitor.
These features make it well-suited for portable and battery-operated devices requiring efficient power regulation.
Pinout
1. VOUT: This pin is the regulated output voltage pin, providing the stable 5.0V output.
2. GND: This is the ground pin, acting as the reference point for the input and output voltages.
3. VIN: The input voltage pin, where the unregulated input voltage is supplied (typically higher than 5.0V).
4. SHUTDOWN (SD): This pin controls the enable/disable function of the regulator. When connected to ground, the regulator is disabled; when connected to a high logic level, the regulator is enabled.
5. N/C (No Connect): This pin is not internally connected but may be used for mechanical stability in the package.
The LP2980AIM5-5.0 is designed for applications requiring a regulated 5.0V output with a low dropout voltage, ensuring efficient operation in battery-powered devices and other low-voltage applications.
