Part Details:

LM105/LM305/LM305A June 1999 LM105/LM305/LM305AVoltage Regulators General Description · DC line regulation guaranteed at 0.03%/V · Ripple rejection on 0.01%V The LM105 series are positive voltage regulators similar tothe LM100, except that an extra gain stage has been added · 45 mA output current without external pass transistor for improved regulation. A redesign of the biasing circuitry re- (LM305A) moves any minimum load current requirement and at the Like the LM100, they also feature fast response to both load V same time reduces standby current drain, permitting higher and line transients, freedom from oscillations with varying re- oltage voltage operation. They are direct, plug-in replacements for sistive and reactive loads and the ability to start reliably on the LM100 in both linear and switching regulator circuits with any load within rating. The circuits are built on a single silicon output voltages greater than 4.5V. Important characteristics chip and are supplied in a TO-99 metal can. of the circuits are: The LM105 is specified for operation for -55°C T A Regulators · Output voltage adjustable from 4.5V to 40V +125°C, and the LM305/LM305A is specified for 0°C T A · Output currents in excess of 10A possible by adding ex- +70°C. ternal transistors · Load regulation better than 0.1%, full load with currentlimiting Schematic and Connection Diagrams Metal Can Package DS007755-3 Top View Order Number LM105H, LM105H/883, SMD #5962-8958801, LM305H or LM305AH See NS Package Number H08C DS007755-1 © 1999 National Semiconductor Corporation DS007755 Absolute Maximum Ratings (Note 1)If Military/Aerospace specified devices are required,please contact the National Semiconductor Sales Office/Distributors for availability and specifications.
