产品概要
描述
LDH85 is a high accuracy voltage regulator designed to be directly connected to car battery in automotive applications or generic battery connected industrial applications. Extended input voltage up to 85 V makes the device capable to support load dump transient, typical in automotive systems. Ultralow 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 LDH85 in shutdown mode allowing a total current consumption lower than 0.6 µA. Thermal protection is also included.
The device is available in automotive grade in a very small footprint DFN package with wettable flank, allowing the maximum space saving in the PCB (printed circuit board) design and AOI (automated optical inspection).
