Frequently Asked Questions

What is the output voltage and current of the LP3856ES-2.5/NOPB?

The LP3856ES-2.5/NOPB provides a fixed 2.5V output voltage with ±2% accuracy and up to 3A continuous output current. The typical dropout voltage is 500mV at full 3A load, making it suitable for high-current, low-headroom applications.

What package does the LP3856ES-2.5/NOPB come in and how many pins does it have?

The LP3856ES-2.5/NOPB is packaged in a SOT-23-5 (5-pin small outline transistor) package. This compact surface-mount footprint is ideal for space-constrained PCB designs in portable and embedded systems.

What are common applications for the LP3856ES-2.5/NOPB?

Common applications include powering DSPs, FPGAs, microcontrollers, and memory devices requiring a 2.5V supply in USB-powered gadgets, industrial control boards, and battery-operated equipment. Its high current capability and low dropout make it a versatile power rail solution.

Is the LP3856ES-2.5/NOPB RoHS compliant and lead-free?

Yes, the LP3856ES-2.5/NOPB is fully RoHS compliant and lead-free (NOPB suffix stands for No Pb/lead). It meets IPC/JEDEC J-STD-020 MSL 1 moisture sensitivity level, allowing storage without special precautions before soldering.

What are equivalent or alternative parts to the LP3856ES-2.5/NOPB?

Close alternatives include the TPS73725 (3A LDO, 2.5V, DSBGA package) and the LP38692MP-2.5/NOPB (similar output, different package). When selecting a replacement, verify input voltage range, dropout voltage, and package compatibility with your design.
