Frequently Asked Questions
What is the output voltage and accuracy of the LP3874EMP-5.0/NOPB?
The LP3874EMP-5.0/NOPB provides a fixed 5V output voltage with ±1.5% accuracy. This tight regulation ensures reliable operation for sensitive digital circuits, microcontrollers, and sensor systems that require a stable 5V power supply.
What is the dropout voltage of the LP3874EMP-5.0/NOPB and why does it matter?
The LP3874EMP-5.0/NOPB has a typical dropout voltage of 0.24V and a maximum of 0.35V at full load. A low dropout voltage means the regulator can maintain its 5V output even when the input voltage is only slightly higher, improving efficiency in battery-powered and low-headroom applications.
What is the input voltage range for the LP3874EMP-5.0/NOPB?
The LP3874EMP-5.0/NOPB accepts an input voltage from 5.35V minimum up to 7V maximum, with an absolute maximum rating of 7.5V. This range suits regulated 6V supplies and slightly elevated 5V bus rails commonly found in industrial and embedded designs.
What package does the LP3874EMP-5.0/NOPB come in and is it RoHS compliant?
The LP3874EMP-5.0/NOPB is housed in a 5-pin SOT-223 package (JESD-30 R-PDSO-G5), which offers good thermal dissipation in a compact footprint. The NOPB suffix confirms the device is lead-free and RoHS compliant, with JESD-609 e3 moisture sensitivity classification.
