ETC LINEARVOLTAGEREGULATORS

Linear Voltage Regulators
Fixed Output
These low cost monolithic circuits provide positive and/or
negative regulation at currents from 100 mA to 3.0 A. They are
ideal for on–card regulation employing current limiting and
thermal shutdown. Low VDiff devices are offered for battery
powered systems.
Although designed primarily as fixed voltage regulators,
these devices can be used with external components to obtain
adjustable voltages and currents.

TA = –40° to +85°C, Case 751, 846A
The MC33264 series are micropower low dropout voltage
regulators available in SO–8 and Micro–8 surface mount
packages and a wide range of output voltages. These devices feature a very low quiescent current (100 µA in the ON
mode; 0.1 µA in the OFF mode), and are capable of supplying output currents up to 100 mA. Internal current and thermal limiting protection is provided. They require only a small
output capacitance for stability.
Additionally, the MC33264 has either active HIGH or active LOW control (Pins 2 and 3) that allows a logic level signal
to turn–off or turn–on the regulator output.
Due to the low input–to–output voltage differential and
bias current specifications, these devices are ideally suited

Low Dropout Regulator
MC33267T, TV
TJ = –40° to +105°C, Case 314D, 314B
The MC33267 is a positive fixed 5.0 V
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.
Due to the low dropout voltage
specifications, the MC33267 is ideally
suited for use in battery powered industrial
and consumer equipment where an
extension of useful battery life is desirable.
This device is contained in an economical
five lead TO–220 type package.

Switching Regulator Control Circuits
These devices contain the primary building blocks which
are required to implement a variety of switching power
supplies. The product offerings fall into three major categories
consisting of single–ended and double–ended controllers,
plus single–ended ICs with on–chip power switch transistors.
These circuits operate in voltage, current or resonant modes
and are designed to drive many of the standard switching
topologies. The single–ended configurations include buck,
boost, flyback and forward converters. The double–ended
devices control push–pull, half bridge and full bridge
configurations.

LM2574N–XX
TJ = –40° to +125°C, Case 626
The LM2574 series of regulators are monolithic integrated
circuits ideally suited for easy and convenient design of a
step–down switching regulator (buck converter). All circuits
of this series are capable of driving a 0.5 A load with excellent
line and load regulation. These devices are available in fixed
output voltages of 3.3 V, 5.0 V, 12 V, 15 V, and an adjustable
output version.
These regulators were designed to minimize the number
of external components to simplify the power supply design.
Standard series of inductors optimized for use with the
LM2574 are offered by several different inductor manufacturers.
Since the LM2574 converter is a switch–mode power supply, its efficiency is significantly higher in comparison with
popular three–terminal linear regulators, especially with higher input voltages. In most cases, the power dissipated by the
LM2574 regulator is so low, that the copper traces on the
printed circuit board are normally the only heatsink needed
and no additional heatsinking is required.
The LM2574 features include a guaranteed ±4% tolerance
on output voltage within specified input voltages and output
load conditions, and ±10% on the oscillator frequency (±2%
over 0°C to +125°C). External shutdown is included, featuring 60 µA (typical) standby current. The output switch includes cycle–by–cycle current limiting, as well as thermal
shutdown for full protection under fault conditions.

demagnetization detection for reduced switching stresses on
transistor and diodes, and a high current totem pole output
ideally suited for driving a power MOSFET. It can also be
used for driving a bipolar transistor in low power converters
(< 150 W). It is optimized to operate in discontinuous mode
but can also operate in continuous mode. Its advanced
design allows use in current mode or voltage mode control
applications.

Critical Conduction SMPS Controller
MC33364D, D1, D2
TJ = –25° to +125°C, Case 751, 751B
The MC33364 series are variable frequency SMPS controllers that operate in the critical conduction mode. They are optimized for low power, high density power supplies requiring
minimum board area, reduced component count, and low
power dissipation. Each narrow body SOIC package provides
a small footprint. Integration of the high voltage startup saves
approximately 0.7 W of power compared to resistor bootstrapped circuits.
Each MC33364 features an on–board reference, UVLO
function, a watchdog timer to initiate output switching, a zero
current detector to ensure critical conduction operation, a
current sensing comparator, leading edge blanking, and a
CMOS driver. Protection features include the ability to shut
down switching, and cycle–by–cycle current limiting.
The MC33364D1 is available in a surface mount SO–8
package. It has an internal 126 kHz frequency clamp. For
loads which have a low power operating condition, the fre-
quency clamp limits the maximum operating frequency, preventing excessive switching losses and EMI radiation.
The MC33364D2 is available in the SO–8 package without
an internal frequency clamp.
The MC33364D is available in the SO–16 package. It
has an internal 126 kHz frequency clamp which is pinned
out, so that the designer can adjust the clamp frequency
by connecting appropriate values of resistance and
capacitance.

Regulation Control Circuit
MC33341P, D
TA = –25° to +85°C, Case 626, 751
The MC33341 is a monolithic regulation control circuit that
is specifically designed to close the voltage and current
feedback loops in power supply and battery charger
applications. This device features the unique ability to perform
source high–side, load high–side, source low–side, and load
low–side current sensing, each with either an internally fixed
or externally adjustable threshold. The various current
sensing modes are accomplished by a means of selectively
using the internal differential amplifier, inverting amplifier, or a
direct input path. Positive voltage sensing is performed by an
internal voltage amplifier. The voltage amplifier threshold is
internally fixed and can be externally adjusted in all low–side
current sensing applications. An active high drive output is

These two series of high speed dual MOSFET driver ICs
are specifically designed for applications requiring low current
digital circuitry to drive large capacitive loads at high slew
rates. Both series feature a unique undervoltage lockout
function which puts the outputs in a defined low state in an
undervoltage condition. In addition, the low “on” state
resistance of these bipolar drivers allows significantly higher
output currents at lower supply voltages than with competing
drivers using CMOS technology.
Logic
The MC34151 series is pin–compatible with the MMH0026 Input A
and DS0026 dual MOS clock drivers, and can be used as
drop–in replacements to upgrade system performance. The
MC34152 noninverting series is a mirror image of the inverting
MC34151 series.
These devices can enhance the drive capabilities of first
generation switching regulators or systems designed with
CMOS/TTL logic devices. They can be used in dc–to–dc Logic

converters, motor controllers, capacitor charge pump
converters, or virtually any other application requiring high
