Instructions for Use:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the specified range of 2.5V to 5.5V. Exceeding this range can damage the device.

2. Output Voltage (VOUT):

   • The output voltage is adjustable and can be set using external resistors. The formula to calculate the output voltage is: [ V_ = V_ left(1 + fracright) ] where ( V_ ) is typically 1.25V.

3. Quiescent Current (IQ):

   • The quiescent current is the current consumed by the regulator when there is no load. It is typically 60 渭A.

4. Dropout Voltage (VDROPOUT):

   • The dropout voltage is the minimum difference between the input and output voltages required to maintain regulation. At full load (1A), it is typically 100 mV.

5. Load Regulation:

   • The load regulation indicates how much the output voltage changes with varying load currents. It is typically 0.5%.

6. Line Regulation:

   • The line regulation indicates how much the output voltage changes with varying input voltages. It is typically 0.05% per volt.

7. Output Current (IOUT):

   • The maximum continuous output current is 1A. Do not exceed this limit to avoid overheating or damage.

8. Thermal Shutdown (TSD):

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

9. Short-Circuit Current (ISC):

   • The maximum short-circuit current is 1.5A. The device has internal protection to limit the current in case of a short circuit.

10. Operating Temperature (TOPR):

    • The device can operate within a temperature range of -40掳C to 125掳C.

11. Storage Temperature (TSTG):

    • The device can be stored within a temperature range of -65掳C to 150掳C.

Additional Notes:

• Ensure proper heat sinking if operating at high output currents or in high ambient temperatures.
• Use appropriate capacitors on the input and output to ensure stability and reduce noise.
• Refer to the datasheet for detailed application circuits and further information.
