1. General description

The NEX90x30-Q100 device is a low-dropout (LDO)

linear regulator designed for applications with input

voltages of up to 40 V. It features a typical quiescent

current (IQ) of only 5.3 μA at light load and a typical

shutdown current (ISHUT) of 300 nA when disabled.

This makes the device ideal for powering always-on

components, such as microcontrollers (MCUs) and

Controller Area Network (CAN) or Local Interconnect

Network (LIN) transceivers in standby or CAN-wake

systems.

In battery-powered automotive applications, low IQ

and ISHUT are critical for saving energy and extending

battery life. Always-on systems require ultra-low IQ

across an extended temperature range to ensure

sustained operation when the vehicle ignition is

off. In CAN-wake systems or certain sleep modes,

maintaining an ultralow ISHUT is essential to minimize

battery consumption even when the system is in sleep

or disabled mode.

The device features integrated protections for

shortcircuit, over-current, and thermal shutdown. It

operates within an ambient temperature range of

-40 °C to 125 °C and a junction temperature range of

-40 °C to 150 °C. Additionally, this device is available in

an enhanced thermal package, HTSSOP8.
