The LP38859SX-1.2 from National Semiconductor is a high-performance linear voltage regulator IC designed for precision power management applications. As part of our PMIC - Voltage Regulators - Linear collection, this component offers exceptional voltage regulation with low dropout characteristics. Featuring thermal shutdown protection and current limiting, this IC maintains stable output voltage even under varying load conditions. These linear regulators are ideal for noise-sensitive applications requiring clean power delivery, such as medical devices, audio equipment, and precision measurement instruments. Typical implementations include power conditioning for microcontroller systems, battery-powered devices, and as post-regulators for switching power supplies.
