MC33264
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

NOTES: 1. Low duty pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
2. Quiescent current is measured where the PNP pass transistor is in saturation. VCE = –0.5 V guarantees this condition.
3. Noise tests on the MC33264 are made with a 0.01 µF capacitor connected across Pins 8 and 5.
