LDH40 Datasheet 200ma Low Dropout Ldo

Manufacturer: STMicroelectronics

Overview: DFN 2x2 6L Wettable Flanks SOT23 5L Maturity status link LDH40 LDH40 Datasheet 200 mA low dropout.

General 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.
