Instructions for Use

1. Input Voltage (V_IN):

   • Ensure the input voltage is within the range of -0.3 V to 45 V.
   • The input voltage must be at least 0.7 V higher than the output voltage to maintain regulation.

2. Output Voltage (V_OUT):

   • The output voltage can be adjusted using external resistors.
   • Use the formula: V_OUT = 1.24 * (1 + R₂/R₁) to set the desired output voltage.

3. Quiescent Current (I_Q):

   • The quiescent current is the current consumed by the regulator when there is no load.
   • It ranges from 40 渭A to 120 渭A with no load.

4. Load Regulation:

   • The change in output voltage due to changes in load current should be minimal.
   • Typically, it is less than 0.1% from 0 mA to 100 mA.

5. Line Regulation:

   • The change in output voltage due to changes in input voltage should be minimal.
   • Typically, it is less than 0.1% per volt from 4.5 V to 45 V.

6. Dropout Voltage (V_DROP):

   • The dropout voltage is the minimum difference between the input and output voltages required to maintain regulation.
   • It ranges from 0.7 V to 1.5 V at 100 mA load current.

7. Output Current (I_OUT):

   • The maximum continuous output current is 100 mA, with a peak of 150 mA.
   • Ensure the input voltage is sufficient to support the desired output current.

8. Thermal Shutdown (T_SHDN):

   • The device will shut down if the temperature exceeds 175掳C to prevent damage.
   • Allow the device to cool before resuming operation.

9. Storage Temperature (T_STG):

   • Store the device in a temperature range of -65掳C to 150掳C to ensure reliability.

10. Capacitor Requirements:

    • Use a 1 渭F ceramic capacitor on the input side and a 1 渭F ceramic capacitor on the output side for stability.
    • Additional capacitance may be required for high-frequency filtering or to reduce output ripple.

11. PCB Layout:

    • Place the input and output capacitors as close as possible to the regulator to minimize inductance and improve stability.
    • Use wide traces for power paths to reduce resistance and heat generation.

12. Heat Dissipation:

    • If operating at high output currents, consider using a heatsink to dissipate heat and keep the device within its thermal limits.
