Input Voltage (V_IN):
- Ensure the input voltage is within the range of 2.7V to 5.5V. Exceeding this range can damage the device.
Output Voltage (V_OUT):
- The output voltage is fixed at 3.3V. No external components are required to set this voltage.
Quiescent Current (I_Q):
- The quiescent current is very low, typically around 1.5μA, making it suitable for battery-powered applications.
Dropout Voltage (V_DROPOUT):
- To minimize dropout voltage, ensure that the difference between input and output voltages remains above 0.3V when delivering up to 100mA.
Load Regulation (ΔV_LOAD):
- For optimal performance, the change in output voltage due to load changes should not exceed 0.5%.
Line Regulation (ΔV_LINE):
- Maintain line regulation below 0.1% by keeping the input voltage within specified limits.
Ripple Rejection (RR):
- The device provides a ripple rejection of 60dB at 1kHz, ensuring clean output under varying conditions.
Operating Temperature (T_OP):
- Operate the device within the temperature range of -40°C to +85°C to ensure reliable performance.
Installation:
- Place the device on a PCB with adequate heat dissipation if operating near the upper temperature limit.
- Use bypass capacitors close to the input and output pins for stable operation.
Handling Precautions:
- Follow ESD protection guidelines during handling and installation to prevent damage to the component.
