Hi team,

Since LP87332D-Q1 is out of stock, can replace LP87332D-Q1 with LP87332B-q1 without any change? Thanks!

Hello Jiawei,

LP87332D-Q1 has default output voltages of 1.15V, 1.06V, 3.3V, and 3.3V. LP87332B-Q1 has default output voltages of 1.255V, 3.3V, 3.3V, and 3.3V. So it won't be a drop-in replacement.

Thanks.

Hi Koskela,

Customer wanted voltage is 1.15V, 1.15V, 3.3V, 3.3V. I think they can change corresponding register to get their wanted voltage output, so they can use same code to get same voltage in LP87332D or LP87332B, right?

Hi Jiawei,

Yes if they can change the voltages through I2C writes that is doable. Note the registers are volatile memory, so the settings will be lost on power down. So the write has to be done on each power up.

Thanks.
