Instructions for Use
Circuit Design:
- Ensure that the input voltage is within the specified range (18 to 30 V).
- Place a 0.33 μF capacitor between the input and ground to stabilize the input.
- Place a 0.1 μF capacitor between the output and ground to stabilize the output.
Heat Dissipation:
- The MC7915CTG and MC7915CT have a thermal resistance of 65 °C/W. Ensure proper heat sinking to maintain the junction temperature within the operating range (-40 to 125 °C).
Short-Circuit and Thermal Protection:
- Both devices include short-circuit and thermal shutdown protection. However, avoid prolonged short circuits as they can lead to excessive heating and potential damage.
Mounting:
- Mount the device on a heatsink if the power dissipation exceeds the safe operating limit without a heatsink.
- Ensure good thermal contact between the device and the heatsink using thermal compound.
Storage:
- Store the devices in a dry environment within the storage temperature range (-65 to 150 °C).
Handling:
- Handle the devices with care to avoid mechanical stress and electrostatic discharge (ESD) damage. Use ESD-safe equipment when handling.
By following these guidelines, you can ensure reliable operation and longevity of the MC7915CTG and MC7915CT regulators.
