DESCRIPTION
  The LP2954 is a fixed voltage micropower voltage regulator with very low quiescent current (90µA typical at 1mA load) and very low dropout voltage (typically 60mV at light loads and 470mV at 250mA load current).
The quiescent current increases only slightly at dropout (120µA typical), which prolongs battery life.
The LP2954 with a fixed output is available in the threelead TO-220, TO-263, and TO-92 packages.
Reverse battery protection is provided.
The tight line and load regulation (0.04% typical), as well as very low output temperature coefficient make the LP2954 well suited for use as a low-power voltage reference.
Output accuracy is guaranteed at both room temperature and over the entire operating temperature range.
