Instructions for Using CM6807G

1. Supply Voltage (VDD):

   • Ensure the input voltage is within the range of 2.7V to 5.5V.
   • Connect the input voltage to the VDD pin.

2. Output Voltage (VOUT):

   • The regulated output voltage is fixed at 3.3V.
   • Connect the load to the VOUT pin.

3. Quiescent Current (IQ):

   • The device consumes approximately 150 μA in active mode.
   • Ensure the power supply can handle this current.

4. Shutdown Current (ISD):

   • When the shutdown pin is pulled low, the device enters a low-power mode consuming about 0.1 μA.
   • Use the shutdown pin to control power consumption.

5. Dropout Voltage (VDO):

   • The device maintains regulation with a dropout voltage of approximately 200 mV.
   • Ensure the input voltage is at least 200 mV higher than the output voltage.

6. Load Regulation:

   • The output voltage may vary by up to 2% with changes in load current.
   • Design the circuit to accommodate this variation if necessary.

7. Line Regulation:

   • The output voltage may vary by up to 0.5% with changes in input voltage.
   • Consider this when selecting the input voltage range.

8. PSRR (Power Supply Rejection Ratio):

   • The device has a PSRR of 70 dB, effectively reducing input ripple.
   • Use appropriate filtering capacitors on the input and output to further reduce noise.

9. Operating Temperature (TJ):

   • The device operates within a junction temperature range of -40°C to 125°C.
   • Ensure proper heat dissipation if operating near the upper limit.

10. Storage Temperature (TS):

    • Store the device in an environment with temperatures ranging from -65°C to 150°C.
    • Avoid exposing the device to extreme temperatures for extended periods.

11. Capacitor Selection:

    • Use a 1 μF ceramic capacitor on the input (VDD) and output (VOUT) pins for stability.
    • Place these capacitors as close as possible to the respective pins to minimize parasitic inductance.

12. PCB Layout:

    • Follow good PCB layout practices to ensure optimal performance.
    • Keep traces short and wide, especially for power and ground connections.
