Instructions for Use
Circuit Connection:
- Connect the input terminal (pin 1) to the negative supply voltage.
- Connect the output terminal (pin 2) to the load.
- Connect the common terminal (pin 3) to ground.
Capacitors:
- Place a 0.33 μF capacitor between the input and ground to filter out high-frequency noise.
- Place a 0.1 μF capacitor between the output and ground to stabilize the regulator.
Heat Dissipation:
- Ensure adequate heat dissipation by mounting the device on a heatsink if the power dissipation exceeds 1W.
- Calculate the power dissipation using the formula: ( P = (V_{text} - V_{text}) times I_{text} ).
Input Voltage:
- The input voltage should be at least 2V higher than the output voltage to ensure proper regulation.
Output Current:
- Do not exceed the maximum continuous output current of 1A to avoid damage to the device.
Operating Temperature:
- Ensure that the operating temperature remains within the specified range of -40°C to 125°C to maintain reliable performance.
Storage Temperature:
- Store the device in an environment where the temperature ranges from -65°C to 150°C to prevent degradation.
Handling:
- Handle the device with care to avoid mechanical stress and static discharge, which can damage the internal components.
Testing:
- Before connecting the device to a live circuit, test it with a known good setup to ensure it is functioning correctly.
Compliance:
- Ensure that the device meets all relevant safety and regulatory standards for your application.
