Linear Regulation Without the Discontinuities

Our linear regulator products deliver accurate voltage regulation with minimal Quiescent Current (IQ) requirements. The product family includes devices with low noise, high power supply rejection capabilities, low-dropout voltages and small packages. Some regulators offer adjustable outputs or additional purchase options for hard-to-find output regulation levels that are suitable for unusual load requirements.

We also offer best-in-class combinations of transient response and quiescent current draw, minimizing the current required by the regulator while still maintaining the ability to respond to changes in the line or load.

Backed by our excellent quality and lifecycle support, you can design or update circuits with these DC regulators knowing the product family has a long manufacturing history. Both the oldest and newest additions to this portfolio will be shipping for many years to come.

In addition, these linear regulators are used in our reference designs and evaluation boards, ensuring compatibility with our microcontrollers (MCUs), sensors, amplifiers and networking devices because they were tested and developed with those loads.

LDOs for Low Quiescent Current

In a world that runs on battery power, the ability to drastically lower power consumption during standby or sleep modes is no longer a luxury. This is especially true in mobile medical applications that have extended use between charging cycles. Consumers are also looking to squeeze every bit of battery power they can from each charge cycle, and that demand requires efficient Low-Dropout (LDO) regulators to optimize standby power usage.

LDOs for Low-Voltage Automotive

We offer several high-voltage LDO regulators for automotive applications. These LDOs feature high operating input voltage ranges (> 45V) and extensive protection capabilities. AEC-Q100 Grade 0 or Grade 1 qualified, these high-performance LDOs are capable of regulating voltages in nearly every automotive application, spanning from switch gear to head units and body electronics.
