DESCRIPTION
  The LP2981 is an efficient linear voltage regulator with ultra-low noise output, very low dropout voltage, and very low ground current.
The LP2981 offers better than 1% initial accuracy. Designed especially for hand-held, battery-powered devices, the LP2981 includes a CMOS or TTL compatible enable/shutdown control input. When shutdown, power consumption drops nearly to zero.
Regulator ground current increases only slightly in dropout, further prolonging battery life.
Key LP2981 features include reversed-battery protection, current limiting, and over temperature shutdown.
The LP2981 is available in fixed output voltage versions in TO-92 and SOT-23-5 package.
