Frequently Asked Questions
What is the output voltage and current rating of the LP3961EMP-5.0?
The LP3961EMP-5.0 provides a fixed 5.0V output voltage with a maximum continuous output current of 1A, making it suitable for powering microcontrollers, sensors, and other moderate-load digital circuits.
What package does the LP3961EMP-5.0 use and what are the thermal benefits?
The LP3961EMP-5.0 is housed in a SOT-223 surface-mount package featuring an exposed thermal pad. This design significantly improves heat dissipation compared to standard SOT-23 packages, allowing the regulator to operate reliably at full 1A load in compact PCB layouts.
What protection features are built into the LP3961EMP-5.0?
The LP3961EMP-5.0 includes internal overcurrent protection and thermal shutdown circuitry. These features automatically limit output current during fault conditions and shut down the device if junction temperature exceeds safe limits, protecting both the regulator and the downstream circuit.
What are typical applications for the LP3961EMP-5.0?
Typical applications include powering 5V logic in embedded systems, industrial sensors, battery-powered portable devices, automotive accessories, and any design requiring a clean, regulated 5.0V rail with up to 1A of output current from a higher input voltage source.
