Instructions for Using the MC34160P

1. Circuit Configuration:

   • Connect the input voltage (VIN) to the input pin.
   • Connect the output voltage (VOUT) to the output pin.
   • Ground the GND pin.
   • Use an external resistor divider to set the output voltage if using an adjustable version.

2. Output Voltage Adjustment:

   • For adjustable output voltage, use the following formula: [ V_ = 1.2V left(1 + fracright) ]
   • Where ( R_1 ) is connected between the output and the feedback pin, and ( R_2 ) is connected between the feedback pin and ground.

3. Capacitor Selection:

   • Use a 1μF ceramic capacitor from the output to ground to ensure stability.
   • A 10μF tantalum or ceramic capacitor can be used for additional filtering.

4. Thermal Considerations:

   • Ensure adequate heat dissipation by using a heatsink or PCB with good thermal conductivity.
   • The device should not exceed the maximum junction temperature of 125°C.

5. Protection Features:

   • The device includes thermal shutdown and current limiting to protect against overtemperature and overload conditions.

6. Package Information:

   • The MC34160P is available in a TO-252 (DPAK) package.

7. Storage and Handling:

   • Store the device in a dry, cool place.
   • Handle with care to avoid static damage.

By following these instructions, you can effectively use the MC34160P in your designs for efficient power regulation.
