300mA, Ultra-low Noise LDO Regulator LP3986-18B3F 1.8V 300mA New original LPS linear regulator IC chip, designed for portable applications with demanding performance and space requirements. The LP3986 performance is optimized for battery-powered systems, providing ultra-low noise and low quiescent current. In addition, the regulator ground current increases only slightly in dropout, further extending battery life.

The LP3986 can also be used with low-ESR ceramic capacitors, reducing the board space required for power applications, which are critical for handheld wireless devices. Other features include ultra-low dropout, high output accuracy, current-limit protection, and a high ripple rejection ratio. Available in a 3-pin SOT-23 package with a silkscreen of 6C*.
