Instructions for RD1679B:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the specified range of 4.5V to 28V.

2. Output Voltage (VOUT):

   • The RD1679B provides a fixed output voltage of 5V. No external components are required for voltage setting.

3. Output Current (IOUT):

   • The device can provide up to 3A continuous output current, with a typical value of 1.5A.

4. Quiescent Current (IQ):

   • The quiescent current is typically 60μA, which helps in maintaining low power consumption during operation.

5. Dropout Voltage (VDROPOUT):

   • The dropout voltage is typically 1.2V at an output current of 1A, ensuring efficient operation even at high loads.

6. Power Supply Rejection Ratio (PSRR):

   • The device has a PSRR of 70dB at 1kHz, effectively reducing noise from the input power supply.

7. Operating Temperature (TOPR):

   • The device operates reliably over a temperature range of -40°C to +125°C.

8. Installation:

   • Place the RD1679B close to the load to minimize trace resistance and inductance.
   • Use appropriate decoupling capacitors near the input and output pins to ensure stability.

9. Thermal Considerations:

   • Ensure adequate heat dissipation if operating at higher currents or temperatures.
