Instructions for Use:

1. Power Supply Connection:

   • Connect the positive terminal of the power supply to the Vin pin.
   • Connect the negative terminal (ground) to the GND pin.

2. Output Configuration:

   • Connect the load to the Vout pin.
   • Ensure the load current does not exceed the maximum output current (300 mA).

3. Capacitor Requirements:

   • Place a 1 渭F ceramic capacitor between Vin and GND as close to the device as possible.
   • Place a 1 渭F ceramic capacitor between Vout and GND to stabilize the output.

4. Thermal Management:

   • Ensure adequate heat dissipation if operating at high currents or temperatures.
   • The device has thermal shutdown protection, but it is recommended to keep the junction temperature below 150掳C.

5. Short-Circuit Protection:

   • The device includes short-circuit protection, which will limit the output current and protect the device from damage.
   • In the event of a short circuit, the device will automatically shut down and restart once the fault is cleared.

6. Operating Conditions:

   • Operate the device within the specified temperature range (-40掳C to 85掳C) for reliable performance.
   • Store the device in a dry environment within the storage temperature range (-65掳C to 150掳C).

7. Ripple Rejection:

   • The device provides good ripple rejection, typically 60 dB, which helps in maintaining a clean output voltage even with noisy input sources.

8. Load and Line Regulation:

   • The device maintains a stable output voltage with changes in load and input voltage, with typical load and line regulation of 2 mV.

9. Dropout Voltage:

   • The dropout voltage is typically 200 mV, allowing the device to operate efficiently even when the input voltage is close to the output voltage.
