Micropower smallCAP
Voltage Regulators with On/Off Control
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 differential 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.
