The MPQ20088-AEC1 is a low-power, low-dropout (LDO) linear regulator that supplies power to systems that are connected to the battery in automotive applications. It includes a wide 3V to 40V input voltage (V_IN) range, making it capable of withstanding transients such as load dump that are anticipated in automotive systems.

With a 45µA quiescent current (I_Q), the MPQ20088-AEC1 is an optimal solution for powering always-on components such as microcontrollers and controller area network transceivers in standby systems. The wide output voltage (V_OUT) range allows the device to generate the bias voltage for silicon carbide (SiC) gate drivers and microphones, as well as power microcontroller units (MCUs) and processors.

The MPQ20088-AEC1 also incorporates exceptionally precise V_OUT accuracy of ±1.5% across line, load, and temperature. This allows the device to quickly react to changes in load or line, such as during cold-crank conditions.

The MPQ20088-AEC1 is available in SOT-89 and TO-252-3 packages, and is available in AEC-Q100 Grade 1. The low thermal resistance enables sustained operation against dissipation across the device.
