1 / 7 page LM105/LM305/LM305A Voltage Regulators General Description The LM105 series are positive voltage regulators similar to the LM100, except that an extra gain stage has been added for improved regulation. A redesign of the biasing circuitry re- moves any minimum load current requirement and at the same time reduces standby current drain, permitting higher voltage operation. They are direct, plug-in replacements for the LM100 in both linear and switching regulator circuits with output voltages greater than 4.5V. Important characteristics of the circuits are: • Output voltage adjustable from 4.5V to 40V • Output currents in excess of 10A possible by adding ex- ternal transistors • Load regulation better than 0.1%, full load with current limiting • DC line regulation guaranteed at 0.03%/V • Ripple rejection on 0.01%V • 45 mA output current without external pass transistor (LM305A) Like the LM100, they also feature fast response to both load and line transients, freedom from oscillations with varying re- sistive and reactive loads and the ability to start reliably on any load within rating. The circuits are built on a single silicon chip and are supplied in a TO-99 metal can. The LM105 is specified for operation for −55˚C ≤ T A ≤ +125˚C, and the LM305/LM305A is specified for 0˚C ≤ T A ≤ +70˚C.
