Instructions for Use:

1. Power Supply Connection:

   • Connect the input voltage (Vin) to the input pin of the 79M15A.
   • Ensure that the input voltage is within the specified range (up to 35V).

2. Output Configuration:

   • The output pin provides a regulated -15V.
   • Connect the output pin to the load or circuit requiring regulated negative voltage.

3. Ground Connection:

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

4. Heat Dissipation:

   • For applications where the regulator dissipates significant power, ensure adequate heat sinking to keep the operating temperature within limits (-40掳C to 85掳C).

5. Capacitor Placement:

   • Place an input capacitor (typically 0.33渭F) close to the input pin to stabilize the input voltage.
   • Place an output capacitor (typically 0.1渭F) close to the output pin to improve transient response and stability.

6. Load Regulation:

   • The load regulation is very low, ensuring stable output voltage over varying load currents from 5mA to 100mA.

7. Line Regulation:

   • The line regulation is also very low, providing a stable output voltage over the specified input voltage range.

8. Dropout Voltage:

   • Be aware of the dropout voltage of 2.8V at 100mA; ensure the input voltage remains sufficiently above the output voltage to maintain regulation.

9. Maximum Ratings:

   • Do not exceed the maximum ratings for input voltage and operating temperature to avoid damage to the device.
