MC33375 Series
300 mA, Low Dropout
Voltage Regulator with
On/Off Control
The MC33375 series are micropower low dropout voltage
regulators available in a wide variety of output voltages as well as
packages, SOT−223 and SOP−8. These devices feature a very low
quiescent current and are capable of supplying output currents up to
300 mA. Internal current and thermal limiting protection are provided
by the presence of a short circuit at the output and an internal thermal
shutdown circuit.
The MC33375 has a control pin 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.
Features:
• Low Quiescent Current (0.3 mA in OFF mode; 125 mA in ON mode)
• Low Input−to−Output Voltage Differential of 25 mV at IO = 10 mA,
and 260 mV at IO = 300 mA
• Extremely Tight Line and Load Regulation
• Stable with Output Capacitance of only 0.33 mF for 2.5 V Output
Voltage
• Internal Current and Thermal Limiting
• Logic Level ON/OFF Control
• Pb−Free Packages are Available
