What are the key features of LT1528CQ#TRPBF?
- 3 A output current with ultra-low 0.57 V typical dropout voltage minimizing power dissipation in battery-powered and automotive designs
- Fixed and adjustable output capability in a single device allowing flexible output voltage programming with external resistors
- 5-pin TO-263 (D2PAK) surface mount package with exposed slug for efficient thermal dissipation at high load currents
What is LT1528CQ#TRPBF used for?
The LT1528CQ#TRPBF is ideal for post-regulation on DC-DC converter outputs in telecom, industrial, and automotive systems where a 3 A supply with minimal headroom loss is required. Its adjustable output mode makes it suitable for programmable bench supplies and embedded processor core rails that need precise, low-noise voltage. The TO-263 package allows compact SMT integration while dissipating up to several watts of thermal load through the board copper.

Frequently Asked Questions
What dropout voltage and output current does the LT1528CQ#TRPBF support?
The LT1528CQ#TRPBF delivers up to 3 A of output current with a typical dropout voltage of only 0.57 V and a worst-case maximum of 0.85 V. This ultra-low dropout characteristic preserves efficiency in systems where the input-to-output differential is small, such as 5 V to 3.3 V conversion.
For a 3.3 V microcontroller supply derived from a 5 V rail, how does the LT1528CQ#TRPBF compare to a standard LDO?
With a typical 0.57 V dropout versus the 1.5 V or more seen on many standard LDOs, the LT1528CQ#TRPBF can regulate 3.3 V from inputs as low as 3.87 V while supplying 3 A, reducing wasted power by over 60% at full load compared to higher-dropout alternatives.
Can the LT1528CQ#TRPBF be used for an adjustable output voltage design?
Yes, the LT1528CQ#TRPBF supports both fixed and adjustable output configurations. In adjustable mode, two external resistors set the output voltage across the full regulated range, allowing designers to target custom rails between the minimum regulated output and the 15 V maximum input limit without changing the IC.
