Product Summary

The LM105H is a positive voltage regulator. 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. The LM105H is direct, plug-in replacements for the LM100 in both linear and switching regulator circuits with output voltages greater than 4.5V.

Parametrics

LM105H absolute maximum ratings: (1)Input Voltage: 50V; (2)Input-Output Differential: 40V; (3)Power Dissipation: 800mW; (4)Operating Temperature Range: -55℃ to 125℃; (5)Storage Temperature Range: -65℃ to 150℃; (6)Lead Temperature (Soldering, 10 seconds): 300℃.

Features

LM105H features: (1)Output voltage adjustable from 4.5V to 40V; (2)Output currents in excess of 10A possible by adding external transistors; (3)Load regulation better than 0.1%, full load with current limiting; (4)DC line regulation guaranteed at 0.03%/V; (5)Ripple rejection on 0.01%V.
