Instructions for LT1076HVCT:

1. Input Voltage Setup:

   • Ensure the input voltage is within the range of 2.5V to 36V. The regulator can handle a wide range of input voltages but should not exceed the maximum limit.

2. Output Voltage Configuration:

   • For adjustable output voltage, use an external resistor divider network connected to the ADJ pin to set the desired output voltage between 1.23V and 35V.

3. Quiescent Current Management:

   • Keep in mind that the quiescent current is typically 40μA at 5V input. This is important for applications where power consumption is a critical factor.

4. Dropout Voltage Consideration:

   • The dropout voltage is around 0.7V at a load current of 150mA. Ensure that the input voltage is sufficiently higher than the desired output voltage by at least this amount.

5. Load and Line Regulation:

   • The device provides excellent load and line regulation of 0.01%. This ensures stable output voltage despite changes in load or input voltage.

6. Power Supply Rejection Ratio (PSRR):

   • At 120Hz, the PSRR is 80dB, which helps in filtering out ripple and noise from the input supply.

7. Operating Temperature Range:

   • The operating temperature range is from -40°C to 125°C, making it suitable for a wide variety of environmental conditions.

8. Capacitor Selection:

   • Choose appropriate input and output capacitors to ensure stability and reduce ripple. Refer to the datasheet for specific capacitor recommendations based on your application requirements.

9. PCB Layout:

   • Pay attention to PCB layout guidelines provided in the datasheet to minimize noise and improve performance. Proper grounding and trace routing are crucial.

10. Protection Features:

    • The device includes internal thermal shutdown and current limiting features to protect against over-temperature and over-current conditions.
