Instructions for Using AOZ1031AI
Input Voltage (VIN):
- Ensure the input voltage is within the range of 2.7V to 5.5V.
- Use appropriate decoupling capacitors (typically 1μF ceramic) close to the input pin to stabilize the input voltage.
Output Voltage (VOUT):
- The output voltage can be adjusted using external resistors. The formula for setting the output voltage is: [ V_ = 0.6V left(1 + fracright) ]
- Choose resistor values to achieve the desired output voltage.
Output Current (IOUT):
- The device can provide up to 1.5A of continuous output current.
- Ensure the load does not exceed this limit to avoid overheating or damage.
Quiescent Current (IQ):
- The quiescent current is typically 30μA at 5V input and no load.
- This value helps in power consumption calculations for low-power applications.
Shutdown Current (ISD):
- When the shutdown pin (SHDN) is pulled low, the device enters a low-power mode with a typical shutdown current of 1μA.
- Use this feature to reduce power consumption when the device is not in use.
Dropout Voltage (VDROPOUT):
- The dropout voltage is the difference between the input and output voltages when the device is operating near its maximum output current.
- For optimal performance, ensure the input voltage is at least 200mV higher than the output voltage.
PSRR (Power Supply Rejection Ratio):
- The PSRR indicates how well the device rejects variations in the input voltage.
- Higher PSRR values mean better rejection of input noise.
Line Regulation:
- Line regulation measures how much the output voltage changes with variations in the input voltage.
- A lower percentage indicates better stability.
Load Regulation:
- Load regulation measures how much the output voltage changes with variations in the load current.
- A lower percentage indicates better stability.
Operating and Storage Temperature Ranges:
- Ensure the device operates within the temperature range of -40°C to 85°C.
- Store the device within the temperature range of -65°C to 150°C to prevent damage.
Additional Notes:
- Always refer to the datasheet for detailed information and specific application notes.
- Proper PCB layout and component placement are crucial for optimal performance and reliability.
