Instructions:
- Supply Voltage (VDD): Ensure the supply voltage is within the specified range of 2.7V to 5.5V to avoid damage to the device.
- Output Current (IOUT): The device can provide a maximum continuous output current of 3.0A. Ensure the load does not exceed this limit.
- Quiescent Current (IQ): The quiescent current is typically 2.5mA and should be considered in power budget calculations.
- Dropout Voltage (VDO): The dropout voltage is the difference between the input and output voltages when the device is operating at full load. It is typically 0.2V but can go up to 0.6V.
- Thermal Shutdown (TSD): The device will shut down if the junction temperature exceeds 160°C to prevent damage.
- Operating Temperature (TA): The ambient operating temperature range is from -40°C to 125°C. Ensure the device operates within this range.
- Junction Temperature (TJ): The maximum junction temperature is 150°C. Exceeding this can cause permanent damage.
- Storage Temperature (TSTG): Store the device in an environment with a temperature range of -65°C to 150°C.
- Output Voltage Range (VOUT): The output voltage can be adjusted between 1.2V and 5.0V using external components.
- Load Regulation: The output voltage may vary by up to 1.0% with changes in load.
- Line Regulation: The output voltage may vary by up to 0.5% with changes in input voltage.
- Ripple Rejection (PSRR): The device provides a power supply rejection ratio of 60dB to 80dB, reducing the effect of input ripple on the output.
- Transient Response: The device should be able to handle rapid changes in load or input voltage without significant overshoot or undershoot.
- Enable Input Voltage (VEN): The enable pin activates the device when the input voltage is between 0.8V and 1.2V.
- Shutdown Current (ISD): When the device is in shutdown mode, the current consumption is typically 0.1μA and can go up to 0.5μA.
