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 for battery powered
computer, consumer, and industrial equipment where an extension of useful
battery life is desirable.
MC33264 Features:
• Low Quiescent Current (0.3 µA in OFF Mode; 95 µA in ON Mode)
• Low Input–to–Output Voltage Dif ferential of 47 mV at 10 mA, and
131 mV at 50 mA
• Multiple Output Voltages A vailable
• Extremely Tight Line and Load Regulation
• Stable with Output Capacitance of Only
0.22 µF for 4.0 V, 4.75 V and 5.0 V Output V oltages
0.33 µF for 2.8 V, 3.0 V, 3.3 V and 3.8 V Output Voltages
• Internal Current and Thermal Limiting
• Logic Level ON/OFF Control
• Functionally Equivalent to TK1 15XXMC and LP2980

DEFINITIONS
Dropout V oltage – The input/output voltage dif ferential at
which the regulator output no longer maintains regulation
against further reductions in input voltage. Measured when
the output drops 100 mV below its nominal value (which is
measured at 1.0 V differential), dropout voltage is affected by
junction temperature, load current and minimum input supply
requirements.
Line Regulation – The change in output voltage for a
change in input voltage. The measurement is made under
conditions of low dissipation or by using pulse techniques such
that average chip temperature is not significantly affected.
Load Regulation – The change in output voltage for a
change in load current at constant chip temperature.
Maximum Power Dissipation – The maximum total
device dissipation for which the regulator will operate within
specifications.
Quiescent Current – Current which is used to operate the
regulator chip and is not delivered to the load.
Output Noise V oltage – The rms ac voltage at the output,
with constant load and no input ripple, measured over a
specified frequency range.

APPLICATION INFORMATION
Introduction
The MC33264 regulators are designed with internal
current limiting and thermal shutdown making them
user–friendly. These regulators require only 0.33 µF (or
greater) capacitance between the output terminal and ground
for stability for 2.8 V, 3.0 V, 3.3 V and 3.8 V output voltage
options. Output voltage options of 4.0 V, 4.75 V and 5.0 V
require only 0.22 µF for stability. The output capacitor must
be mounted as close to the MC33264 as possible. If the
output capacitor must be mounted further than two
centimeters away from the MC33264, then a larger value of
output capacitor may be required for stability . A value of 0.68
µF or larger is recommended. Most types of aluminum,
tantalum or multilayer ceramic will perform adequately. Solid
tantalums or appropriate multilayer ceramic capacitors are
recommended for operation below 25°C.
A bypass capacitor is recommended across the MC33264
input to ground if more than 4.0 inches of wire connects the
input to either a battery or power supply filter capacitor.
On/Off Control
On/Off control of the regulator may be accomplished in
either of two ways. Pin 3 may be tied to circuit ground and a
positive logic control applied to Pin 2. The regulator will be
turned on by a positive (>2.4 V) level, typically 5.0 V with
respect to ground, sourcing a typical current of 6.0 µA. The
regulator will turn off if the control input is a logic “0”
(<0.5 V). Alternatively, Pin 2 may be tied to the regulator
input voltage and a negative logic control applied to Pin 3.
The regulator will be turned on when the control voltage is
less than Vin – 2.4 V , sinking a typical current of 18 µA when
Vin = 6.0 V. The regulator is off when the control input is
open or greater than Vin – 0.2 V.
Programming The Output Voltage
The MC33264 output voltage is automatically set using its
internal voltage divider. Alternatively, it may be programmed
within a typical ±15% range of its preset output voltage. An
external pair of resistors is required, as shown in Figure 7.

the feedback pin bias current, nominally –20 nA. The
minimum recommended load current of 1.0 µA forces an
upper limit of 1.2 MΩ on the value of R2, if the regulator must
work with no load. IFB will produce a 2% typical error in V
out
which may be eliminated at room temperature by adjusting
R1. For better accuracy, choosing R2 = 100 K reduces this
error to 0.17% while increasing the resistor program current
to 12 µA.
Output Noise
In many applications it is desirable to reduce the noise
present at the output. Reducing the regulator bandwidth by

increasing the size of the output capacitor is the only method
for reducing noise.
Noise can be reduced fourfold by a bypass capacitor
across R1, since it reduces the high frequency gain from 4 to
unity for the MC33264D–5.0. Pick

or about 0.01 µF. When doing this, the output capacitor must
be increased to 3.3 µF to maintain stability. These changes
reduce the output noise from 430 µV to 100 Vrms for a
100 kHz bandwidth for the 5.0 V output device. With the
bypass capacitor added, noise no longer scales with output
voltage so that improvements are more dramatic at higher
output voltages.
