Instructions for Using the LT1076HVCR:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 2.5V to 40V.
   • Use appropriate input capacitors to stabilize the input voltage.

2. Output Voltage (VOUT):

   • The output voltage can be set using external resistors according to the formula: [ V_ = 1.23 left(1 + fracright) ]
   • Choose resistor values to achieve the desired output voltage.

3. Quiescent Current (IQ):

   • The quiescent current is typically 60 渭A. This should be considered in low-power applications.

4. Output Current (IOUT):

   • The maximum continuous output current is 150 mA. Ensure the load does not exceed this limit to avoid overheating or damage.

5. Dropout Voltage (VDROPOUT):

   • The dropout voltage is typically 1.2V. Ensure the input voltage is at least 1.2V higher than the output voltage to maintain regulation.

6. Power Supply Rejection Ratio (PSRR):

   • The PSRR is 80 dB at 120 Hz, indicating good rejection of ripple and noise from the input supply.

7. Load Regulation:

   • The load regulation is 0.01%, meaning the output voltage will change by only 0.01% for a full load step.

8. Line Regulation:

   • The line regulation is also 0.01%, ensuring minimal changes in output voltage with variations in input voltage.

9. Operating Temperature (TOPR):

   • The device can operate within a temperature range of -40掳C to 125掳C. Ensure proper heat sinking if operating near the upper limit.

10. Storage Temperature (TSTG):

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

11. Capacitors:

    • Use ceramic or tantalum capacitors for input and output filtering. Typical values are 10 渭F for input and 10 渭F for output.

12. Layout Considerations:

    • Keep the layout compact to minimize parasitic inductance and capacitance.
    • Place the output capacitor as close as possible to the output pin.

13. Stability:

    • Ensure the loop stability by selecting appropriate compensation components, such as an external capacitor on the COMP pin if required.

14. Protection:

    • The device includes internal thermal shutdown and current limiting to protect against overtemperature and overload conditions.
