LM305 - Voltage Regulators

Download the LM305 datasheet PDF. This datasheet also covers the LM3 variant, as both devices belong to the same voltage regulators family and are provided as variant models within a single manufacturer datasheet.

Description

The LM105 series are positive voltage regulators similar to the LM100, except that an extra gain stage has been added for improved regulation.

LM105/LM305/LM305A Voltage Regulators June 1999 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.
