Instructions:

1. Mounting: Ensure the VHF28-12IO5 is mounted on a heatsink if operating at or near maximum output current to prevent overheating.
2. Input Voltage: Connect the input terminal to a power source within the specified input voltage range (4.5V to 16V).
3. Output Connections: Connect the load requiring regulated 5V directly to the output terminal ensuring it does not exceed the maximum output current of 1.2A.
4. Capacitors: For stable operation, place a 0.1μF ceramic capacitor close to the input pin and a 1μF electrolytic capacitor close to the output pin.
5. Temperature Monitoring: Operate within the specified temperature range (-40°C to 85°C) to ensure reliability and longevity.
6. Polarity Check: Verify correct polarity of input and output connections before applying power to avoid damage.
