Instructions for Use:

1. Power Supply Connection: Connect the input voltage between 4.5V and 20V to the input pin. Ensure that the input voltage does not exceed the maximum rating to avoid damage.
2. Output Configuration: The PS21965-AST provides a fixed 3.3V output. Connect your load directly to the output pins, ensuring it does not exceed the 1.5A continuous output current limit.
3. Heat Management: For applications where the device may dissipate significant power, ensure adequate heat sinking or cooling is provided, especially when operating near the upper limits of the input voltage range or at higher ambient temperatures.
4. Temperature Considerations: Operate the device within the specified operating temperature range (-40°C to 85°C). Store the device in an environment within the storage temperature range (-65°C to 150°C).
5. Quiescent Current: Be aware of the quiescent current draw of 60μA to optimize power consumption in low-power applications.
6. Dropout Voltage: Note the dropout voltage of 1.2V at full load. Ensure the input voltage remains sufficiently above the output voltage to maintain regulation under all operating conditions.
