Instructions for KIA7912P-U/PK:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 2.7V to 5.5V for reliable operation.

2. Output Voltage (VOUT):

   • The device provides a fixed output voltage of 1.2V. No external components are required for setting this voltage.

3. Quiescent Current (IQ):

   • At an input voltage of 3.6V, the quiescent current is typically 80μA. This low current consumption makes it suitable for battery-operated applications.

4. Dropout Voltage (VDROPOUT):

   • When delivering up to 100mA with an input voltage of 3.3V, the dropout voltage is typically 280mV. Ensure that the input voltage is sufficiently higher than the output voltage to maintain regulation.

5. Load and Line Regulation:

   • The load regulation is 0.2% over the load current range from 0mA to 150mA, ensuring stable output voltage.
   • The line regulation is 0.1% over the input voltage range from 2.7V to 5.5V, providing consistent performance across different input voltages.

6. Power Supply Rejection Ratio (PSRR):

   • The PSRR at 1kHz is 70dB, indicating good noise suppression from the input supply.

7. Operating Temperature:

   • The device can operate in junction temperatures ranging from -40°C to +125°C, making it suitable for a wide range of environmental conditions.

8. Mounting and Handling:

   • Handle the component carefully to avoid damage. Follow standard ESD (Electrostatic Discharge) precautions during installation.

9. PCB Layout:

   • Ensure proper PCB layout practices to minimize noise and ensure optimal performance. Place bypass capacitors close to the input and output pins as recommended by the manufacturer.
