Thermal Resistance, Junction-to-Case (SOT-223) RθJC 15 °C/W

Key Features

  • Low Quiescent Current: 0.3 µA in OFF mode and 125 µA in ON mode.
  • Low Input-to-Output Voltage Differential: 25 mV at IO = 10 mA.
  • On/Off Control: A control pin allows a logic level signal to turn-off or turn-on the regulator output.
  • Internal Protection: Current limiting and thermal shutdown protection.
  • Output Capacitance: Requires only a 0.33 µF (or greater) capacitance between the output and ground for stability.
  • Package Options: Available in SOT-223 and SOP-8 packages.

Applications

The MC33375ST-3.0T3 is ideally suited for battery-powered computer, consumer, and industrial equipment where an extension of useful battery life is desirable. Its low quiescent current and low input-to-output voltage differential make it particularly useful in applications requiring efficient power management.

Q & A

  1. What is the maximum output current of the MC33375ST-3.0T3? The maximum output current is 300 mA.
  2. What is the typical dropout voltage of the MC33375ST-3.0T3? The typical dropout voltage is less than 260 mV.
  3. What are the package options for the MC33375 series? The MC33375 series is available in SOT-223 and SOP-8 packages.
  4. How does the on/off control work on the MC33375ST-3.0T3? The on/off control is managed through a control pin that allows a logic level signal to turn-off or turn-on the regulator output.
  5. What is the operating ambient temperature range for the MC33375ST-3.0T3? The operating ambient temperature range is from -40°C to +125°C.
  6. What kind of internal protection does the MC33375ST-3.0T3 have? The device features internal current limiting and thermal shutdown protection.
  7. How much capacitance is required for stability between the output and ground? A capacitance of 0.33 µF (or greater) is required between the output and ground for stability.
  8. What is the maximum junction temperature for the MC33375ST-3.0T3? The maximum junction temperature is 150°C.
  9. How does the thermal protection work on the MC33375ST-3.0T3? The thermal protection disables the output when the junction temperature exceeds 150°C and re-enables it once the temperature drops below this threshold.
  10. What are some typical applications for the MC33375ST-3.0T3? Typical applications include battery-powered computer, consumer, and industrial equipment where efficient power management is necessary.
