What are the key features of LT1528CQ#PBF?
- Low-dropout regulator with 0.57 V typical / 0.85 V maximum dropout at 3 A output current
- Fixed and adjustable output voltage options in a single device for flexible power-rail design
- 3 A continuous output current capability suitable for mid-power embedded and industrial loads
- Maximum 15 V input voltage rating with single-output positive regulation
- 5-pin DDPAK (TO-263) power package for efficient PCB-mount thermal dissipation
What is LT1528CQ#PBF used for?
LT1528CQ#PBF is commonly used in embedded systems, industrial control boards, and communication equipment that require a stable regulated voltage rail with up to 3 A of load current. Its low dropout characteristic makes it well suited for applications powered by lithium-ion batteries or unregulated DC adapters where input-to-output headroom is limited. It also serves as a post-regulator in mixed-signal boards where clean, low-noise supply voltage is needed for ADCs, sensors, and analog front ends.

Frequently Asked Questions
At full 3 A load, how much headroom does LT1528CQ#PBF need between input and output voltage?
LT1528CQ#PBF has a typical dropout voltage of 0.57 V and a maximum of 0.85 V at 3 A output current, meaning a very small input-to-output differential is required, making it ideal for battery-powered designs with tight voltage budgets.
Which PCB thermal management approach works best when LT1528CQ#PBF dissipates power in the 5-DDPAK package?
The 5-pin DDPAK (TO-263) package provides a large exposed metal tab that can be soldered directly to a PCB copper pour or heatsink pad, enabling efficient conduction cooling when the device is dissipating several watts at 3 A continuous output.
Can LT1528CQ#PBF operate from a 12 V input rail to supply a 5 V system load?
Yes. With a 12 V input and 5 V output, the input-to-output differential is 7 V, well within the 15 V absolute maximum input voltage rating, and the dropout condition is not a concern at that headroom level.
Is LT1528CQ#PBF the right choice for a design requiring both fixed and adjustable output voltage options?
LT1528CQ#PBF supports both fixed and adjustable output configurations, giving designers the flexibility to set the output voltage for 3.3 V, 5 V, or other values using external resistors, while delivering up to 3 A continuous load current.
