| MILITARY DATA SHEET MNLM105-X REV 0B0 VOLTAGE REGULATOR General Description 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. It 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 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, it 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 circuit is built on a single silicon chip. The LM105 is specified for operation for -55 C < TA < +125 C.

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. 2 MNLM105-X REV 0B0 MILITARY DATA SHEET Electrical Characteristics DC PARAMETERS (The following conditions apply to all the following parameters, unless otherwise specified.)
