Instructions:
- Power Supply Connection: Ensure the input voltage is within the specified operating range of 4.5V to 28V.
- Output Configuration: Choose the appropriate fixed output voltage option (1.8V, 2.5V, or 3.3V) based on your application requirements.
- Current Limitation: The device can provide up to 1A of continuous output current. Design your circuit to ensure this limit is not exceeded.
- Thermal Management: Operate within the specified temperature range (-40°C to +85°C). For extended storage, keep within -55°C to +150°C.
- Noise Reduction: To minimize noise, place a 1μF capacitor close to the input and output pins.
- PSRR Consideration: The power supply rejection ratio of 70dB at 1kHz helps in filtering out ripple and noise from the input supply.
- Dropout Voltage: At higher output currents, consider the dropout voltage to avoid undervoltage situations.
Ensure all connections are secure and double-check polarity before powering the device to prevent damage.
