Part Number: LP87322E-Q1

Hello,

I have few queries on regarding LP87322E-Q1 UVLO set-up & schematics implementation, please clarify the following:

1. How to Adjust UVLO for LP87322E-Q1??

2. Programmable Output Voltage given in datasheet is: 0.7 V to 3.36 V

                   - My application requires 3.5V, is it possible to set it using external voltage divider circuitry?? If Yes, please let me know how the connections should be.

Thanks in advance.

    Hi Madhu,

    > 1. How to Adjust UVLO for LP87322E-Q1??

    UVLO is a fixed level, 2.6V falling and 2.63V rising (typical). This is specified on the "PROTECTION FUNCTIONS" section of the electrical characteristics table.

    I would not recommend this. The device is validated and specified up to 3.36V. I am not sure that it will meet specification when operating at a higher voltage.
