What are the key features of LT3033EUDC#PBF?
- Ultra-low 95 mV typical dropout at 3 A output enables high efficiency regulation from near-rail input voltages
- Programmable current limit via external resistor protects load circuits and enables accurate charge current control in battery systems
- Adjustable 0.95 V to 10 V output range covers FPGA core, DDR memory, and processor I/O supply rails in a single design
- 20-pin QFN package with exposed pad provides excellent thermal dissipation for sustained 3 A output without external heatsink
What is LT3033EUDC#PBF used for?
The LT3033EUDC#PBF is designed for post-regulation of switching converter outputs in FPGA, DSP, and high-performance processor power systems where low-noise, accurate supply voltage is critical. Its ultra-low 95 mV dropout allows it to follow closely behind a buck regulator output with minimal input-output headroom, maximizing overall system efficiency. The programmable current limit feature is also leveraged in battery formation chargers, laboratory bench supplies, and precision current sources requiring adjustable protection thresholds.

Frequently Asked Questions
What is the typical dropout voltage of the LT3033EUDC#PBF at full 3 A load, and how does that compare to standard LDOs?
The LT3033EUDC#PBF has a typical dropout voltage of only 95 mV at 3 A output current, with a maximum specification of 240 mV. Standard LDO regulators commonly exhibit 500 mV to 1.2 V dropout at comparable currents, so the LT3033 allows the input rail to be set 400 mV to 1 V lower, directly reducing power dissipation and heat in the regulator.
How is the current limit of the LT3033EUDC#PBF programmed, and what protection scenarios does this enable?
The LT3033EUDC#PBF current limit is set by connecting an external resistor between the ILIM and SET pins. By selecting resistor values, the designer can program the fold-back threshold anywhere from under 1 A to the full 3 A range, enabling load protection against short-circuits, inrush current limiting during capacitor charging, and precise charge current control in battery management systems.
What output voltage range does the LT3033EUDC#PBF support, and which digital IC supply rails does it cover?
The LT3033EUDC#PBF is adjustable from 0.95 V to 10 V via an external resistor divider. This spans FPGA core rails at 0.95 V to 1.0 V, DDR4 VDDQ at 1.2 V, processor I/O at 1.8 V and 3.3 V, and legacy 5 V logic supplies, making a single regulator model suitable for diverse digital supply requirements across a product platform.
How does the 20-pin QFN package of LT3033EUDC#PBF manage thermal dissipation at 3 A continuous output?
The 20-pin QFN package incorporates a large exposed thermal pad on its bottom surface that transfers heat directly to the PCB copper plane, achieving junction-to-board thermal resistance of approximately 20°C/W to 30°C/W with proper via stitching. At 3 A with 0.5 V input-output differential, total power dissipation is 1.5 W, which the package can sustain with modest copper pours without requiring an external heatsink.
