Instructions for Using SY8088AAC

1. Supply Voltage (VCC):

   • Ensure the supply voltage is within the specified range of 2.7V to 5.5V.
   • Connect the VCC pin to the power source and GND to ground.

2. Output Voltage (VOUT):

   • The output voltage can be adjusted between 1.8V and 3.3V using external resistors.
   • Use the formula ( V_ = 1.23 left(1 + fracright) ) to set the desired output voltage, where ( R_1 ) and ( R_2 ) are the resistor values.

3. Quiescent Current (IQ):

   • The quiescent current is typically 1.2μA and should not exceed 2.0μA.
   • This is the current consumed by the device when it is active but not supplying any load.

4. Shutdown Current (ISD):

   • To put the device into shutdown mode, apply a low signal to the SHDN pin.
   • The shutdown current is typically 0.1μA and should not exceed 0.5μA.

5. Load Regulation:

   • The load regulation is typically 0.5% and should not exceed 1.0%.
   • This indicates how much the output voltage changes with varying load conditions.

6. Line Regulation:

   • The line regulation is typically 0.1% and should not exceed 0.3%.
   • This indicates how much the output voltage changes with varying input voltage.

7. Dropout Voltage:

   • The dropout voltage is typically 0.2V and should not exceed 0.4V.
   • This is the minimum difference between the input and output voltages required for the regulator to maintain regulation.

8. Operating Temperature (TOPR):

   • The device operates reliably within the temperature range of -40°C to 85°C.
   • Ensure that the ambient temperature does not exceed these limits.

9. Storage Temperature (TSTG):

   • The device can be stored in temperatures ranging from -65°C to 150°C.
   • Avoid exposing the device to extreme temperatures for extended periods.

10. Capacitor Selection:

    • Use appropriate input and output capacitors to ensure stability and filter noise.
    • Typical values are 1μF for the input capacitor and 1μF for the output capacitor.

11. PCB Layout:

    • Place the input and output capacitors as close as possible to the respective pins.
    • Use short and wide traces to minimize inductance and resistance.

12. Handling:

    • Handle the device with care to avoid static discharge and physical damage.
    • Follow standard ESD (Electrostatic Discharge) precautions during assembly and testing.
