The LT1117IST#PBF is an adjustable low dropout (LDO) positive linear regulator from Analog Devices, designed to deliver up to 800mA of continuous output current. The device provides an adjustable output voltage set by a pair of external resistors, with a typical output range from 1.25V to the maximum input voltage minus dropout, allowing flexible rail generation from a single regulator. Integrated features include internal current limiting and thermal overload protection, which enhance system reliability. This regulator is housed in an industry-standard SOT-223 surface-mount package that offers a small footprint while providing adequate power dissipation for moderate loads. It remains stable with a wide range of output capacitor types and values, simplifying design-in for engineers.
Typical applications span industrial automation, instrumentation, medical devices, and point-of-load regulation in communications equipment, where a stable, low-noise power rail for microcontrollers, sensors, or analog circuits is critical. The LT1117IST#PBF is specified for operation over the industrial temperature range of -40°C to +125°C, making it well-suited for embedded systems in harsh thermal environments, including aerospace and defense platforms that demand high-reliability components. As an active product from Analog Devices, it benefits from extended lifecycle support, though designers in regulated industries should verify long-term availability for program timelines. The lead-free, RoHS-compliant finish (denoted by the #PBF suffix) meets global environmental requirements. The SOT-223 package is widely sourced, reducing single-supply risk, and the adjustable output capability allows the same part to be used across multiple voltage rails, streamlining BOM management.
