Instructions for Using SAE81C90

1. Supply Voltage (VDD):

   • Ensure the supply voltage is within the range of 2.0V to 5.5V to avoid damage or improper operation.

2. Quiescent Current (IQ):

   • The quiescent current is typically 1.5μA and can go up to 3.0μA. This is the current drawn by the device when there is no load.

3. Output Current (IOUT):

   • The device can provide a continuous output current of up to 100mA. For optimal performance, keep the output current below this limit.

4. Output Voltage (VOUT):

   • The regulated output voltage is 1.8V. Ensure that the load requires this voltage level.

5. Dropout Voltage (VDROPOUT):

   • The dropout voltage is the minimum difference between the input and output voltages required for the regulator to maintain regulation. It is typically 100mV and can go up to 200mV.

6. Shutdown Current (ISD):

   • When the device is in shutdown mode, the supply current drops to a very low level, typically 0.1μA to 0.5μA.

7. Thermal Shutdown (TSD):

   • The device will automatically shut down if the temperature exceeds 160°C to prevent thermal damage.

8. Operating Temperature (TOPR):

   • The device is designed to operate within an ambient temperature range of -40°C to 85°C.

9. Storage Temperature (TSTG):

   • Store the device in an environment with a temperature range of -65°C to 150°C to ensure long-term reliability.

10. Layout Considerations:

    • Use short and wide traces for power and ground connections to minimize inductance and improve stability.
    • Place bypass capacitors close to the input and output pins to filter noise and stabilize the output.

11. Application Notes:

    • Refer to the datasheet for specific application notes and circuit diagrams to ensure proper integration into your design.
