NEX90240BPA-Q100 Production

400 mA, 40 V, ultra-low Iq (5.3 mA), low-dropout voltage regulator

The NEX90240-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 (Isd) of 300 nA when disabled. This makes the device ideal for powering always-on components, such as microcontroller units (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 Isd 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 ultra-low Isd is essential to minimize battery consumption even when the system is in sleep or disabled mode.

The device features integrated protections for short circuit, 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.

Interactive datasheet

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
