LDO

Last updated May 21, 2025, generated by Sumble

What is LDO?

LDO stands for Low-Dropout Regulator. It is a type of voltage regulator that can regulate the output voltage even when the input voltage is only slightly higher than the desired output voltage. LDOs are commonly used in portable devices and battery-powered systems to provide a stable voltage supply to sensitive components while minimizing power loss.

What other technologies are related to LDO?

LDO Competitor Technologies

CHARGE-PUMP

Charge pumps are used to generate different voltage levels, and can be used as voltage regulators, in place of LDOs, though they are usually less efficient. They are an alternative for voltage regulation.

Buck

Buck converters are switching regulators that step down voltage efficiently and serve as an alternative to LDOs, especially at higher currents where efficiency is more critical. A buck converter is a type of DC/DC converter.

buck-boost

Buck-boost converters can step up or step down voltage, providing more flexibility than LDOs, though typically at the cost of greater complexity and potentially lower efficiency. A buck-boost converter is a type of DC/DC converter.

PMIC

PMICs integrate multiple power management functions, including voltage regulation, and can replace multiple discrete LDOs. PMICs often include LDOs, but also buck converters and other regulators.

SMPS

SMPS (Switch Mode Power Supplies) are switching regulators that offer higher efficiency than LDOs, serving as an alternative for voltage regulation. Includes buck, boost, and buck-boost converters.

Boost

Boost converters are switching regulators that step up voltage efficiently and serve as an alternative to LDOs, especially where voltage needs to be increased. A boost converter is a type of DC/DC converter.

DC/DC converter

DC/DC converters provide voltage conversion using switching techniques, offering higher efficiency than LDOs and serving as an alternative. Includes buck, boost, and buck-boost.

DC/DC

DC/DC converters provide voltage conversion using switching techniques, offering higher efficiency than LDOs and serving as an alternative. Includes buck, boost, and buck-boost.
