LM105/LM205/LM305/LM305A,

LM376 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 character-

istics of the circuits are:

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

resistive and reactive loads and the ability to start reliably on

any load within rating. The circuits are built on a single sili-

con chip and are supplied in a TO-99 metal can.

Output voltage adjustable from 4.5V to 40V

125 C, and the LM305/LM305A is specified for 0 C

The LM105 is specified for operation for 55 C

Output currents in excess of 10A possible by adding

external transistors

70 C.

Load regulation better than 0.1%, full load with current

limiting
