Instructions for Using the MC34160P
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.
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.
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.
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.
Protection Features:
- The device includes thermal shutdown and current limiting to protect against overtemperature and overload conditions.
Package Information:
- The MC34160P is available in a TO-252 (DPAK) package.
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.
