Instructions for Use:
Supply Voltage (Vcc):
- Ensure the supply voltage is within the range of 2.7V to 5.5V to avoid damage to the device.
Output Current (Iout):
- The device can provide a continuous output current of up to 1.5A. For optimal performance, keep the load current below 1.0A.
Quiescent Current (IQ):
- The quiescent current is typically 1.0mA with no load. This should be considered when designing low-power applications.
Dropout Voltage (Vdo):
- The dropout voltage is the difference between the input and output voltages at which the regulator can no longer maintain regulation. It is typically 0.5V at 150mA.
Line Regulation:
- The line regulation is the change in output voltage due to changes in input voltage. It is typically 0.01% per volt.
Load Regulation:
- The load regulation is the change in output voltage due to changes in load current. It is typically 0.01% per milliamp.
Thermal Shutdown (TSD):
- The device will automatically shut down if the junction temperature exceeds 150°C to prevent damage.
Short-Circuit Protection (SCP):
- The device includes short-circuit protection, which limits the output current to approximately 1.5A to prevent damage during short circuits.
PCB Layout Considerations:
- Use a good thermal design to ensure proper heat dissipation. Place the device on a PCB with adequate copper area or a heatsink if necessary.
- Keep the input and output capacitors close to the device to minimize noise and improve stability.
Capacitors:
- Use a 1μF ceramic capacitor on the input and a 1μF ceramic capacitor on the output for stability. Higher values may be used for additional filtering.
Storage and Handling:
- Store the device in a dry, cool place to avoid moisture damage.
- Handle the device with care to avoid static discharge, which can damage the internal components.
