Instructions for Use
Supply Voltage (Vcc):
- Ensure the supply voltage is within the range of 4.5V to 5.5V.
- Exceeding this range can damage the device.
Operating Current (Iop):
- The typical operating current is 20mA. Ensure the power supply can provide sufficient current.
Peak Current (Ipk):
- The device can handle peak currents up to 50mA for short durations.
Output Voltage (Vo):
- The output voltage is typically 3.3V. Ensure your circuit is designed to operate at this voltage.
Output Ripple (Vr):
- The output ripple is typically 50mV peak-to-peak. Use appropriate filtering if lower ripple is required.
Efficiency (η):
- The efficiency is typically 85%. This may vary depending on load conditions.
Operating Temperature (Topr):
- The device is designed to operate between -40°C and 85°C. Avoid operating outside this range to prevent damage.
Storage Temperature (Tstg):
- Store the device between -55°C and 125°C to ensure long-term reliability.
Quiescent Current (Iq):
- The quiescent current is typically 1.5mA. This is the current drawn by the device when no load is applied.
Load Regulation (ΔVo/ΔIL):
- The load regulation is typically 0.5mV/mA. This indicates how much the output voltage changes with load current.
Line Regulation (ΔVo/ΔVin):
- The line regulation is typically 0.1mV/V. This indicates how much the output voltage changes with input voltage.
Additional Notes:
- Always use appropriate decoupling capacitors near the power input to reduce noise and improve stability.
- Ensure proper heat dissipation if the device is operating at high currents or temperatures.
- Refer to the datasheet for more detailed information and specific application notes.
