Instructions for Use:

  1. Input Connection:

    • Connect the input voltage to the "IN" pin.
    • Ensure the input voltage is within the specified range (-20V to -30V).
  2. Output Connection:

    • Connect the load to the "OUT" pin.
    • The output voltage will be regulated to -15V.
  3. Ground Connection:

    • Connect the ground (GND) pin to the common ground of the circuit.
  4. Capacitors:

    • Place a 0.33 μF ceramic capacitor between the "IN" and "GND" pins as close to the device as possible.
    • Place a 1 μF tantalum capacitor between the "OUT" and "GND" pins to ensure stability.
  5. Thermal Considerations:

    • The 79L15A has a maximum power dissipation based on the thermal resistance of the package and the ambient temperature. Ensure proper heat sinking if operating at high currents or in high-temperature environments.
  6. Transient Protection:

    • Consider adding transient protection devices (e.g., TVS diodes) to protect against voltage spikes.
  7. Storage:

    • Store the device in a dry environment within the specified storage temperature range (-65°C to 150°C).
  8. Handling:

    • Handle with care to avoid damage to the pins and the device itself. Follow ESD (Electrostatic Discharge) precautions to prevent damage from static electricity.

By following these guidelines, you can ensure reliable operation of the 79L15A negative voltage regulator.
