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.
