Instructions for Use:
Supply Voltage (Vcc):
- Ensure the supply voltage is within the range of 4.5V to 5.5V to avoid damage to the device.
Quiescent Current (Iq):
- The quiescent current is typically 10mA at 5V. This should be considered in power budget calculations.
Output Voltage (Vo):
- The output voltage is fixed at 3.3V under no load conditions. It remains stable across different load conditions.
Output Current (Io):
- The device can provide up to 200mA continuously. For higher currents, consider using a heatsink or a more powerful regulator.
Dropout Voltage (Vd):
- The dropout voltage is typically 0.5V at 100mA. Ensure the input voltage is at least 0.5V higher than the output voltage to maintain regulation.
Line Regulation (ΔVo/ΔVi):
- The line regulation is very good, with a typical value of 0.1% over the specified input voltage range.
Load Regulation (ΔVo/ΔIo):
- The load regulation is also excellent, with a typical value of 0.1% over the specified output current range.
Ripple Rejection (RR):
- The device provides good ripple rejection, typically 70dB from 10Hz to 100kHz, ensuring clean output voltage.
Thermal Shutdown (TSD):
- The device will shut down if the temperature exceeds 150°C to prevent damage. Allow the device to cool down before resuming operation.
Short-Circuit Protection (SCP):
- The device includes short-circuit protection to safeguard against accidental short circuits. The protection circuit will automatically reset once the fault condition is removed.
Additional Notes:
- Capacitors:
- Use appropriate input and output capacitors to stabilize the voltage and reduce noise. Typically, a 10μF ceramic capacitor on the input and a 10μF ceramic capacitor on the output are recommended.
- PCB Layout:
- Ensure proper PCB layout with short traces and adequate ground planes to minimize noise and improve thermal performance.
