Key Features
- Fixed 5 V output at up to 1.5 A suits high-current logic and analog supply rails in industrial and communications equipment
- 1.3 V typical dropout voltage allows regulation from 6.5 V inputs common in AC adapter and automotive accessory applications
- TO-220 through-hole package with metal tab enables direct heatsink attachment for power dissipation above 2 W
- 20 V maximum input (30 V absolute max) provides wide headroom for unregulated DC adapter supplies
Applications
The LT1086CT-5#PBF is commonly used to supply 5 V regulated power to microcontrollers, FPGAs, and analog front-end circuits in industrial control systems powered from 9–20 V unregulated DC adapters. Its 1.5 A output current and TO-220 heatsink capability make it suitable for multi-board rack systems distributing local 5 V rails. The device is also used in laboratory instruments, test equipment, and embedded single-board computers requiring a reliable, low-noise 5 V reference power supply.

Frequently Asked Questions
What is the dropout voltage of the LT1086CT-5#PBF at full 1.5 A load, and what does that require of the input supply?
The LT1086CT-5#PBF has a typical dropout voltage of 1.3 V and a maximum of 1.5 V at 1.5 A load. To maintain the 5 V output at full load, the input must be at least 5 V + 1.5 V = 6.5 V, which matches the specified minimum input voltage. A 9 V or 12 V DC adapter provides ample margin over the 6.5 V threshold across the full load range.
How much power does the LT1086CT-5#PBF dissipate at 1.5 A from a 12 V input, and what heatsink is needed?
At 12 V input and 5 V output with 1.5 A load, power dissipation is (12 - 5) x 1.5 = 10.5 W. The TO-220 junction-to-case thermal resistance is typically 4°C/W. Without a heatsink, the junction temperature would rise to unsafe levels, so a heatsink with thermal resistance below 4°C/W is required to keep the junction below 125°C in a 25°C ambient environment.
When would the LT1086CT-5#PBF be chosen over a switching regulator for a 12 V to 5 V conversion at 1 A?
The LT1086CT-5#PBF is preferred when low output noise is critical — for example, powering sensitive analog front-ends, RF circuits, or precision ADCs where switching noise at 100 kHz to 2 MHz would degrade measurement accuracy below the 16-bit level. Its linear topology produces no switching artifacts, unlike a buck converter, at the cost of higher power dissipation (7 W at 1 A from 12 V).
What is the input voltage range and absolute maximum of the LT1086CT-5#PBF, and which supply sources are compatible?
The device operates from 6.5 V minimum to 20 V maximum input, with a 30 V absolute maximum rating. This makes it compatible with standard 9 V, 12 V, and 15 V AC adapter outputs, as well as automotive 12 V accessory rails (which can reach 15–16 V during alternator charging). The 30 V absolute max provides protection against common automotive load-dump spikes up to 24 V on 12 V systems.
