Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions.

The LM105 positive voltage regulator is similar to the LM100, except that an extra gain stage has been added for improved regulation. A redesign of the biasing circuitry removes any minimum load current requirement and at the same time reduces standby current drain, permitting higher voltage operation. LM105 is a direct, plug-in replacement for the LM100 in both linear and switching regulator circuits with output voltages greater than 4.5V.
Important characteristics of the circuit LM105 is:
-  Output voltage adjustable from 4.5V to 40V
-  Output currents in excess of 10A possible by adding external transistors
-  Load regulation better than 0.1%, full load with current limiting
-  DC line regulation guaranteed at 0.30%/V
-  Ripple rejection on 0.01%/V
As with the LM100, LM105 also features fast response to both load and line transients, freedom from oscillations with varying resistive and reactive loads and the ability to start reliably on any load within rating. The LM105 is built on a single silicon chip. The LM105 is specified for operation for -55 C TA +125 C.
