LP87523-Q1: difference between multi part number

Hi Colt,

The different part numbers (C/D/E/J) indicate different pre-configured default register settings. These determine the output voltages, start-up and shut-down sequencing, as well as several other settings. So you cannot use one device in place of another. Each of these devices has a Technical Reference Manual on the product page (https://www.ti.com/product/LP87523-Q1 ) that describes these register settings for each device. 

Best regards,

Matt
