» Product Change Notification
The MC33275 series are micropower low dropout (LDO) linear voltage regulators available in a wide variety of output voltages as well as packages, DPAK, SOT-223, and SOP-8 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.

The MC33275 is available as a MC33375 which includes an On/Off control.

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 (125 mA)
  • Low Input-to-Output Voltage Differential of 25 mV at IO = 10mA, 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
Applications
  • Battery Powered Consumer Products
  • HandHeld Instruments
  • Camcorders and Cameras
