MC33375/D
MC33375, NCV33375 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 A in OFF mode; 125 A in ON mode)
• Low Input−to−Output Voltage Differential of 25 mV at I
O
= 10 mA,
and 260 mV at I
O
= 300 mA
• Extremely Tight Line and Load Regulation
• Stable with Output Capacitance of only 0.33 F for 2.5 V Output
Voltage
• Internal Current and Thermal Limiting
• Logic Level ON/OFF Control
• NCV Prefix for Automotive and Other Applications Requiring
Unique Site and Control Change Requirements; AEC−Q100
Qualified and PPAP Capable
• These are Pb−Free Devices

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. V

O
− 0.5] V guarantees this condition.
3. For 1.8 V version V
