Low Power Regulator

agileLDO_LP

product icon for Low Power Regulator

Product Overview

The agileLDO_LP is a linear regulator, suitable for use in any low power, low current system and is designed to provide a flexible range of regulated output voltages suitable for ultra-low power systems and near-vt operating modes.

The agileLDO_LP consists of: A voltage reference generator, an error amplifier and a output current source. The regulated output voltage is fed-back into the error amplifier to maintain a constant regulated output over the specified range of input voltages and load currents.

Agile Analog designs are based on tried and tested architectures to ensure reliability and functionality. Our design methodology is programmatic, systematic and repeatable leading to analog IP that is more verifiable, more robust and more reliable. Our methodology also allows us to quickly re-target our IP to different process options. We support all the major foundries including TSMC, GlobalFoundries, Samsung Foundry and SMIC as well as other IC foundries and manufacturers.

Key Information
