Application Notes
- AN-181 3-Terminal Regulator is Adjustable (Rev. B)PDF, 314 Kb, Revision: B, File published: May 5, 2013
Until now all of the 3-terminal power IC voltage regulators have a fixed output voltage. In spite of this limitation their ease of use low cost and full on-chip overload protection have generated wide acceptance. Now with the introduction of the LM117 it is possible to use a single regulator for any output voltage from 1.2 V to 37 V at 1.5A.
