Instructions for MC79L12ACP

1. Power Supply Connection:

   • Connect the input voltage (VIN) to the input pin.
   • Ensure the input voltage is at least 2.5V higher than the output voltage (-12V).

2. Output Connection:

   • Connect the output pin to the load requiring a regulated -12V supply.

3. Ground Connection:

   • Connect the ground pin to the common ground of your circuit.

4. Capacitors:

   • Place a 0.1μF ceramic capacitor between the input pin and ground close to the device.
   • Optionally, place a 1μF tantalum capacitor between the output pin and ground for improved transient response.

5. Heat Dissipation:

   • For applications with high current or high ambient temperatures, consider adding a heat sink.

6. Short Circuit Protection:

   • The device includes internal short-circuit protection, but ensure external circuits do not exceed the maximum short-circuit current of 300mA.

7. Operating Temperature:

   • Ensure the operating temperature stays within -40°C to +85°C for reliable operation.
