Instructions for Use:
- Power Supply Connection: Connect the input voltage (V_IN) to a stable power source within the specified range of 5.5V to 20V.
- Output Configuration: Ensure the output voltage (V_OUT) is connected to your load. The device regulates this to approximately 5V.
- Heat Management: Monitor the junction temperature to ensure it stays within the operational limits (-40°C to 125°C). Use heatsinks if necessary, especially under high load conditions.
- Load Limitation: Do not exceed the maximum load current of 100mA to prevent damage to the regulator.
- Capacitor Placement: For stability, place a 1μF ceramic capacitor close to the input pin and another 1μF ceramic capacitor close to the output pin.
- Quiescent Current Awareness: Be aware that the quiescent current can vary from 6μA to 10μA, which may impact battery life in low-power applications.
- Dropout Consideration: Account for the dropout voltage (0.5V to 1.0V) when designing circuits to ensure efficient operation.
This table and these instructions provide key parameters and guidelines for using the UPC79N05H voltage regulator effectively.
