LM1086ISX-5.0

LM1086ISX-5.0 Description

The LM1086ISX-5.0 from Texas Instruments is a high-performance, fixed-output 5V linear voltage regulator designed for demanding applications requiring stable power delivery. With a 1.5A output current capability and a low dropout voltage of 1.5V @ 1.5A, this regulator ensures efficient operation even with tight input-output differentials. Its 25V maximum input voltage and robust over-current, over-temperature, and short-circuit protection make it suitable for harsh environments. The device features a 68dB PSRR at 120Hz, minimizing noise and ripple for sensitive circuits. Packaged in a surface-mount format, it is RoHS3 compliant and rated for MSL 3 (168 hours) moisture sensitivity, ensuring reliability in industrial and commercial applications.
