Frequently Asked Questions
What is the LP3856ES-1.8/NOPB and what output voltage does it provide?
The LP3856ES-1.8/NOPB is a high-current LDO (Low Dropout) linear voltage regulator from Texas Instruments that provides a fixed 1.8V output. It can supply up to 3A of continuous output current with a typical dropout voltage of only 340mV at full load, making it ideal for powering 1.8V rails in FPGAs, DSPs, and memory devices.
What package and pin count does the LP3856ES-1.8/NOPB use?
The LP3856ES-1.8/NOPB comes in a D2PAK (TO-263) surface-mount package with 3 pins (Input, Output, Ground). The large thermal pad of the D2PAK package allows excellent heat dissipation, supporting the 3A output current without a bulky heatsink in many applications.
What is the operating temperature range of the LP3856ES-1.8/NOPB?
The LP3856ES-1.8/NOPB operates over a wide temperature range of -40C to +125C, making it suitable for both industrial and automotive-grade environments where thermal robustness is critical.
What are good alternative parts to the LP3856ES-1.8/NOPB?
Compatible alternatives include the LP3856ES-1.8 (same device with lead finish), TPS7A8001 (adjustable high-current LDO from TI), and LT3080 from Analog Devices for parallel operation. Verify the output voltage, dropout voltage, and package footprint for drop-in compatibility.
Is the LP3856ES-1.8/NOPB RoHS compliant and what does NOPB mean?
Yes, the LP3856ES-1.8/NOPB is fully RoHS compliant and lead-free. The /NOPB suffix (No Lead, Pb-Free) means all terminations use SAC solder alloy instead of tin-lead, complying with EU RoHS Directive 2011/65/EU.
