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 Differential of 47 mV at 10 mA, and

131 mV at 50 mA

• Multiple Output Voltages Available

• 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 Voltages

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 TK115XXMC and LP2980

DEFINITIONS

Dropout Voltage – 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 Voltage – The rms ac voltage at the output,
with constant load and no input ripple, measured over a
specified frequency range.
