What are the key features of LT3080EQ#PBF?
- 1.1 A output current with only 0.35 V typical dropout enabling efficient low headroom regulation
- Parallel-capable architecture allows multiple LT3080 units to be combined for higher output current without external current balancing resistors
- Wide 26 V maximum input-output differential supports regulation from high-voltage rails down to low-voltage logic supplies
What is LT3080EQ#PBF used for?
LT3080EQ#PBF is used in post-regulation stages of multi-output power supplies where precise, low-noise voltage rails are required for analog and RF circuits. Its parallel operation feature enables scalable current delivery in server and telecom equipment by connecting multiple units together without ballast resistors. The DDPAK-5 power package facilitates heatsinking in space-constrained industrial designs requiring 1.1 A or higher current through paralleling.

Frequently Asked Questions
How can multiple LT3080EQ#PBF devices be combined for output currents above 1.1 A?
LT3080EQ#PBF supports parallel operation using a single SET resistor shared across all paralleled units. Because the output voltage is set by a resistor to ground rather than a resistor divider, paralleling two units doubles the available output current to 2.2 A with inherent current sharing, and three units yield 3.3 A, without external current-balancing circuitry.
What dropout voltage and input range should be expected when using LT3080EQ#PBF in a 5 V to 3.3 V regulation path?
In a 5 V input to 3.3 V output path, the 1.7 V headroom well exceeds the 0.35 V typical dropout of the LT3080EQ#PBF, allowing full 1.1 A output without saturation. The 1 V minimum and 26 V maximum input-output differential means this regulator also handles conversion from 12 V or 24 V rails down to logic-level outputs in the same design.
In which thermal conditions does the DDPAK-5 package of LT3080EQ#PBF outperform an SOT-223 alternative?
The DDPAK-5 (also known as D2PAK or TO-263-5) provides significantly lower junction-to-case thermal resistance than SOT-223, typically below 3°C/W versus 8°C/W for SOT-223. At 1.1 A output with 2 V dropout (2.2 W dissipation), the DDPAK-5 package keeps junction temperature rise below 7°C on a standard copper pad, where a SOT-223 would see over 17°C rise under the same conditions.
