regulator and supervisory circuit contain-
ing many of the necessary monitoring
functions
based systems. It is specifically designed
for appliance and industrial applications
offering the designer a cost effective
solution with minimal external components.
These integrated circuits feature a 5.0 V,
100 mA regulator with short circuit current
limiting, pinned out 2.6 V bandgap
reference, low voltage reset comparator,
power warning comparator with program-
mable hysteresis, and an uncommitted
comparator ideally suited for microproces-
sor line synchronization.
input for low standby current, and internal
thermal shutdown for over temperature
protection.
dual–in–line heat tab plastic package for
improved thermal conduction.
Low Dropout Regulator
MC33267T, TV
T J = –40 to +105 C, Case 314D, 314B
regulator that is specifically designed to
maintain proper voltage regulation with an
extremely low input–to–output voltage
differential. This device is capable of
supplying output currents in excess of 500
mA and contains internal current limiting and
thermal shutdown protection. Also featured
is an on–chip power–up reset circuit that is
ideally suited for use in microprocessor
based systems. Whenever the regulator
output voltage is below nominal, the reset
output is held low. A programmable time
delay is initiated after the regulator has
reached its nominal level and upon timeout,
the reset output is released.
specifications, the MC33267 is ideally
suited for use in battery powered industrial
and
extension of useful battery life is desirable.
This device is contained in an economical
five lead TO–220 type package.
