300mA Low Dropout Linear Regulator

General Description

The LP3986 is a 300mA fixed output voltage low dropout linear regulator operating from 2.5V to 5.5V input. Typical ground current is approximately 90μA. Built-in output current-limiting and thermal-limiting provide maximal protection against any fault conditions. The LP3986 is available in 1.5V,1.8V,2.5V,2.8V , 3V,3.3V and 3.5V versions.
