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 45V Important character-
istics of the circuits are
Output voltage adjustable from 45V to 40V
Output currents in excess of 10A possible by adding
external transistors
Load regulation better than 01% full load with current
DC line regulation guaranteed at 003%V
Ripple rejection on 001%V
45 mA output current without external pass transistor
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
The LM105 is specified for operation for b55 C s TA s
125 C and the LM305LM305A is specified for 0 C s TA
s a
70 C
