LDH40 Description

LDH40 is a high accuracy voltage regulator designed to be directly connected to a car battery in automotive applications, or a generic battery connected in industrial applications. Extended input voltage up to 40 V makes the device capable to support a load dump transient, typical in automotive systems. Ultra-low quiescent current at light load increases the battery operation lifetime in always-on-standby systems.
