DIA7865

Automotive 300 mA, High-Voltage, Ultra-Low Quiescent

Current, Low-Dropout Regulator

Description

The DIA7865 is a low-dropout linear regulator designed to function with an input voltage range from 3 V to

40 V. With a minimum operation of 3 V, the DIA7865 can function normally during cold-crank and start and

stop conditions. The DIA7865 provides an ideal solution for powering microcontrollers (MCUs) and CAN/LIN

transceivers in standby systems for its typical quiescent current at no load is only 4 µA.

In always-on systems, low quiescent current (I_Q) is important for power saving and prolonging battery lifetime,

especially in automotive battery-connected applications, which must include ultra-low quiescent current.

To match the needs of automotive applications’ power supply, a short-circuit and overcurrent protection is

included in the device. In addition, to dissipate the heat, a thermally conductive package is placed to ensure

the device can function sustainably.
