“Many lithium-battery-powered devices require voltage rails in the 2.8-V to 3.6-V range for RF, audio, or motor applications. The ADP2503 and ADP2504 are ideal regulators to provide these voltages when board area and efficiency are important,” said Arcadio Leon, marketing director for portable power products, Analog Devices.

Proprietary Buck-Boost Architecture Results in Excellent Transient Performance and High Efficiency

The ADP2503 and ADP2504 regulators are based on ADI’s new proprietary current-mode buck-boost architecture, achieving glitchless mode transitions and outstanding transient performance across line and load. This high level of output stability is critical for powering sensitive analog and digital circuitry. The devices also feature one of the industry’s lowest no-load quiescent current (Iq) levels38
