Regulators

Did you know Allegro now provides one of the industry's largest selection of wide-input, Grade 0, automotive and industrial power management ICs? 

Our regulator solutions provide industry-leading value—offering high quality and meaningful integration. They're also robust, efficient and feature high temperature operation (150°C). 

We test our regulator solutions in our own EMC labs, ensuring they meet stringent EMC requirements, and provide proven EMC reference designs for our customers.

Automotive Regulators

Our unique solutions work with input voltages from 2.8V to 50V for 12V/24V automotive applications, and generate output rails that power microprocessors, transceivers, sensors and displays. We offer cutting edge ASIL-D certified PMICs for safety automotive applications, enabling low FIT-level system designs and small footprint solutions. Single output regulators are available across a range of output current capabilities, and many offer “low Iq” operation to allow keepalive supplies to minimize current drawn from the battery input.
