Description

General part information

LDL40 Series

LDL40 is a high accuracy voltage regulator designed to be directly connected to a car battery in automotive applications or a generic battery used in industrial applications. Extended input voltage up to 40 V makes the device able to support a load dump transient, which is typical in automotive systems. Ultra-low quiescent current at light load increases the battery operation lifetime in always-on-standby systems.

The device is stabilized with a small ceramic capacitor on the input and output.

An enable logic control function puts the LDL40 in shutdown mode allowing a total current consumption lower than 0.3 µA. Thermal protection is also included.
