Instructions for Use:

1. Supply Voltage (VDD):

   • Ensure the supply voltage is within the range of 2.7V to 5.5V to avoid damage to the device.

2. Input Voltage (VIN):

   • The input voltage should not exceed 5.8V relative to GND to prevent damage.

3. Output Voltage (VOUT):

   • The 67L110 provides a fixed output voltage of 3.3V. No external components are required for voltage regulation.

4. Output Current (IOUT):

   • The maximum continuous output current is 110 mA. Ensure that the load does not exceed this limit to avoid overheating or damage.

5. Quiescent Current (IQ):

   • The quiescent current is typically 1.0 渭A, which is very low, making the 67L110 suitable for battery-powered applications.

6. Dropout Voltage (VDROPOUT):

   • The dropout voltage is typically 0.2V at full load. This means the input voltage must be at least 0.2V higher than the output voltage (3.3V) to maintain regulation.

7. Load Regulation:

   • The output voltage will change by no more than 0.5% when the load current changes from 0 to 110 mA.

8. Line Regulation:

   • The output voltage will change by no more than 0.1% when the input voltage changes from 2.7V to 5.5V.

9. Ripple Rejection:

   • The device provides good ripple rejection, typically between 60 dB and 80 dB at 1 kHz, which helps in maintaining a clean output voltage.

10. Operating Temperature (TJ):

    • The device can operate over a junction temperature range of -40掳C to 125掳C. Ensure proper heat dissipation if operating at high temperatures.

11. Storage Temperature (TSTG):

    • The device can be stored in temperatures ranging from -65掳C to 150掳C without damage.

Additional Notes:

• Capacitors:
  • It is recommended to place a 1 渭F ceramic capacitor close to the input pin (VIN) and a 1 渭F ceramic capacitor close to the output pin (VOUT) to ensure stability and reduce noise.
• PCB Layout:
  • Proper PCB layout is crucial for optimal performance. Keep the ground plane solid and minimize trace lengths to reduce parasitic inductance and resistance.
