Instructions for Use:
Power Supply:
- Ensure the supply voltage (VDD) is within the range of 2.7V to 5.5V.
- Connect the power supply to the VDD pin and ground to the GND pin.
Output Configuration:
- The output current (IOUT) can be up to 200mA continuously.
- Adjust the output voltage (VOUT) using the external resistor network or internal settings as per the datasheet.
Temperature Considerations:
- The operating temperature range is from -40°C to 85°C.
- The storage temperature range is from -65°C to 150°C.
- Ensure the thermal resistance (θJA) is considered for proper heat dissipation.
Quiescent Current:
- The typical quiescent current (IQ) is 1.5μA at VDD = 3.3V and TA = 25°C.
Regulation:
- The load regulation and line regulation are both 0.05%/V.
Enable Pin:
- The enable input high level (VENH) should be between 1.2V and 5.5V.
- The enable input low level (VENL) should be between 0V and 0.8V.
- When the enable pin is low, the device enters shutdown mode with a typical shutdown current (ISD) of 0.1μA.
Installation and Handling:
- Handle the device with care to avoid damage from electrostatic discharge (ESD).
- Follow the recommended PCB layout guidelines to ensure optimal performance and reliability.
Testing:
- Before finalizing the design, test the device under various operating conditions to ensure it meets the required specifications.
