60 mA buck for 24 V industrial rails
The LT1934IS6-1#TRMPBF is a step-down (buck) switching regulator from Analog Devices, delivering up to 60 mA output current from a 3.2 V to 34 V input range. That 34 V max input covers 24 V industrial supplies with headroom for transients, and the adjustable output down to 1.25 V lets it power low-voltage logic, sensor rails, or bias supplies from a single rail. It is a non-synchronous design — an external Schottky catch diode is required in the BOM, which adds a component but keeps the quiescent current low for always-on loads.
Package and thermal reality
Housed in a 6-lead TSOT-23-6 (SOT-23 Thin) package, the part is surface-mount and occupies minimal board area. The small footprint limits thermal dissipation — at 60 mA output from a 24 V rail, the power loss heats the junction above ambient; the -40°C to 125°C operating range gives margin for enclosed or under-hood environments, but the layout should use the copper pour under the device as a heatsink.
Active lifecycle, no sourcing pressure
Listed as Active with ROHS3 compliance, this part has no last-time-buy or obsolescence deadline. Standard procurement applies — quoted to order against the BOM quantity through independent distribution.
