The LDO output is also adjustable, from 0.6 V to 14.5 V, but current-limited to 10 mA. That LDO is not meant for a heavy load — it is sized for a low-power analog rail, a reference voltage, or a keep-alive supply. Because both converters share the same die and package, the thermal path is shared: the buck's power dissipation heats the LDO pass element, so watch the total power budget if you run both outputs near their limits at high ambient temperature. The exposed pad (MSOP-EP) needs a good thermal via pattern to the ground plane to keep the junction temperature under control. That means Analog Devices is still manufacturing it, and there is no last-time-buy or end-of-life notice on record.","metaTitle":"LTC3104EMSE#PBF Dual-Output Buck + LDO Regulator, 1.2MHz","metaDescription":"LTC3104EMSE#PBF from Analog Devices: dual-output step-down synchronous buck (300mA) and LDO (10mA), 1.2MHz switching, -40°C to 125°C, 16-MSOP-EP.
