ADI LT3645IMSE#PBF

降压（1），线性（LDO）（1）20.8V ~ 16V，500mA3.6V ~ 36V

Overview

The LT3645IMSE is a dual output regulator combining a 500mA buck regulator and a 200mA low dropout linear regulator (LDO). The wide input voltage range of 3.6V to 36V makes the LT3645IMSE suitable for regulating power from a wide variety of sources, including 24V industrial supplies and automotive batteries. Its high operating frequency allows the use of tiny, low cost inductors and capacitors, resulting in a very small solution.

Other features of the LT3645IMSE include a <2μA shutdown, short circuit protection, soft-start and thermal shutdown. The LT3645IMSE is available in the thermally enhanced 16-lead (3mm × 3mm) QFN package, or a 12-lead MSE package.
