LM1085IS-5.0/NOPB Description

Short technical summary and product information.

The LM1085IS-5.0/NOPB is a versatile 3-A low dropout positive linear voltage regulator manufactured by Texas Instruments. Designed for efficiency and reliability, it features a maximum input voltage of 29V and a minimum output voltage of 1.25V, with a maximum output of 27.5V. This regulator is available in both adjustable and fixed output voltage versions, including common options like 3.3V, 5.0V, and 12V.

 

Key electrical characteristics include a typical dropout voltage of 1300mV at 3A, a typical quiescent current of 5mA, and excellent line and load regulation at 0.015% and 0.1% respectively. It also provides a typical noise of 38 µVrms and a PSRR of 30 dB at 100 KHz.

 

The LM1085 series is designed with integrated current limiting and thermal shutdown for protection. It shares the same pin-out as the industry-standard LM317. This regulator is suitable for applications requiring a stable and reliable power source. It is available in TO-263 and TO-220 package types, supporting surface mount and through-hole mounting respectively.
