Frequently Asked Questions
What is the output voltage and current rating of the LP3853ES-2.5/NOPB?
The LP3853ES-2.5/NOPB provides a fixed 2.5V output with a maximum continuous output current of 3A. The dropout voltage is typically 340mV at full load, making it suitable for applications where the input supply is only slightly above 2.5V.
What package does the LP3853ES-2.5/NOPB use, and how many pins does it have?
It uses a 5-pin SOT-223-5 surface-mount package. The exposed thermal pad on the bottom significantly improves heat dissipation compared to standard SOT-223 packages, allowing it to deliver the full 3A current rating with proper PCB copper pours.
What are common applications for the LP3853ES-2.5/NOPB?
Typical applications include FPGA and DSP core voltage rails, post-regulation stages in switching power supplies, portable industrial instruments, automotive infotainment modules, and battery-powered devices requiring a clean, stable 2.5V rail with low noise and high PSRR.
Is the LP3853ES-2.5/NOPB RoHS-compliant and lead-free?
Yes. The NOPB suffix denotes a lead-free, RoHS-compliant version using a tin-silver-copper solder finish. It meets all major environmental compliance directives including EU RoHS and China RoHS 2.
What are good pin-compatible or functionally equivalent alternatives to the LP3853ES-2.5/NOPB?
Close alternatives include the LP38502-2.5 (same TI family, TO-263 package), LT1764A-2.5 from Analog Devices (4A output, similar dropout), and AMS1117-2.5 for lower current designs. Always verify input voltage range, dropout, and pinout compatibility before substitution.
