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 removes 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: DC line regulation guaranteed at 0.
03%/V Ripple rejection on 0.
01%V 45 mA output current wit...
