Instructions for NJM78L05

1. Input Voltage (VIN):

   • Ensure the input voltage is within the operating range of 7.2V to 30V.
   • A higher input voltage will increase power dissipation and may require a heat sink.

2. Output Voltage (VOUT):

   • The output voltage is regulated to 5V under no load conditions.
   • Use appropriate capacitors at input and output for stability and noise reduction.

3. Output Current (IOUT):

   • The device can supply up to 100mA continuously.
   • For higher current requirements, consider using additional cooling or a different regulator.

4. Line Regulation (ΔVLINE):

   • The change in output voltage due to variations in input voltage is minimal, typically 0.04V across the specified input range.

5. Load Regulation (ΔVLOAD):

   • Output voltage changes by approximately 1mV when the load current varies from 0 to 100mA.

6. Dropout Voltage (VDROPOUT):

   • At full load (100mA), the dropout voltage is around 1.8V. Ensure the input voltage is sufficiently higher than the output voltage.

7. Quiescent Current (IQ):

   • The quiescent current is about 6mA when there is no load on the output.

8. Ripple Rejection (ΔVRIPPLE):

   • The device provides good ripple rejection, typically 80dB at 120Hz, which helps in maintaining a stable output.

9. Operating Temperature (TOPR):

   • Operate the device within the temperature range of -40°C to 85°C for reliable performance.

10. Storage Temperature (TSTG):

    • Store the device between -55°C and 150°C to ensure long-term reliability.

Ensure proper PCB layout and component selection to achieve optimal performance.
