Automotive grade LDOs boost accuracy, deliver ultra-low quiescent current
EP&T Magazine
Automation / Robotics Electronics Power Supply / Management SemiconductorsNEXPERIA NEX90x30-Q100 series of AEC-Q100 qualified general-purpose low-dropout (LDO) voltage regulators provide ultra-low quiescent current. Product series includes tracking LDOs with high tracking accuracy and protected outputs, capable of direct connection to vehicle batteries thanks to their wide input voltage tolerance. LDOs are thermally enhanced and can generate a stable voltage source under cold-crank conditions for ripple-sensitive loads in automotive applications including infotainment systems, ADAS as well as telematics and lighting systems. Tracking LDO’s output protection enables their use in body control modules, zone controller units and power train systems, even in scenarios involving off-board loads such as sensors. Beyond automotive applications, these LDOs are well-suited for industrial applications, including power tools, e-bikes and battery packs.
