LTC3388-3 - 20V High Efficiency Nanopower Step-Down Regulator

Download the LTC3388-3 datasheet PDF. This datasheet also covers the LTC3388-1 variant, as both devices belong to the same 20v high efficiency nanopower step-down regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The LTC®3388-1/LTC3388-3 are high efficiency step-down DC/DC converters with internal high side and synchronous power switches that draw only 720nA typical DC supply current at no load while maintaining output voltage regulation.
