MC33275_05 Datasheet, PDF (1/15 Pages) ON Semiconductor – 300 mA, Low Dropout Voltage Regulator

MC33275, NCV33275
300 mA, Low Dropout
Voltage Regulator
The MC33275 series are micropower low dropout voltage
regulators available in a wide variety of output voltages as well as
packages, SOT−223, SOP−8, DPAK, and DFN 4x4 surface mount
packages. 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.
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 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 mF for 2.5 V Output
Voltage
• Internal Current and Thermal Limiting
• NCV Prefix for Automotive and Other Applications Requiring Site
and Control Changes
• Pb−Free Packages are Available
Applications
• Battery Powered Consumer Products
• Hand−Held Instruments
• Camcorders and Cameras
