Analog Devices Inc. LT3667EUDD is a highly integrated power management IC featuring a triple output voltage regulator. This component combines one step-down (buck) regulator with two linear (LDO) regulators, offering a flexible solution for power delivery in demanding applications. The buck converter operates within a switching frequency range of 243kHz to 2.2MHz, supporting input voltages from 1.6V to 45V. It provides a regulated output up to 400mA. The two LDO outputs each deliver up to 200mA with adjustable output voltages from 0.8V to 38.6V. The device is supplied in a 24-pin QFN (3x5) package suitable for surface mounting. Its robust design and multiple regulation topologies make it well-suited for use in automotive, industrial control, and portable electronics where efficient and precise power distribution is critical. The operating temperature range is -40°C to 125°C.
