Instructions for Using MIC5253-1.8YC5TR

1. Input Voltage (VIN):

   • Ensure the input voltage is within the operating range of 1.7V to 5.5V.
   • Use a decoupling capacitor (typically 1μF ceramic) close to the input pin to stabilize the input voltage.

2. Output Voltage (VOUT):

   • The output voltage is fixed at 1.8V. No external components are required to set this voltage.

3. Quiescent Current (IQ):

   • The quiescent current is very low, typically 1.2μA to 2.5μA, making it suitable for low-power applications.

4. Dropout Voltage (VD):

   • The dropout voltage is 0.25V at 100mA load current. This means the input voltage should be at least 0.25V higher than the output voltage to maintain regulation.

5. Load Regulation:

   • The load regulation is 0.5% from 0mA to 100mA. This indicates the output voltage will remain stable under varying load conditions.

6. Line Regulation:

   • The line regulation is 0.1% from 1.7V to 5.5V. This ensures the output voltage remains stable with changes in input voltage.

7. Power Supply Rejection Ratio (PSRR):

   • The PSRR is 60dB at 1kHz, indicating good noise rejection from the input supply.

8. Thermal Shutdown (TSD):

   • The device has thermal shutdown protection that activates at approximately 150°C to prevent damage from overheating.

9. Operating Temperature (TOPR):

   • The device can operate in temperatures ranging from -40°C to 85°C.

10. Storage Temperature (TSTG):

    • Store the device in temperatures ranging from -65°C to 150°C.

11. Layout Considerations:

    • Place the input and output capacitors as close as possible to the respective pins to minimize parasitic inductance and ensure stability.
    • Use a ground plane to improve thermal performance and reduce noise.

12. Handling Precautions:

    • Handle the device with care to avoid static discharge, which can damage the internal components.
    • Follow proper soldering techniques to avoid thermal stress during assembly.
