The LP3962ES-2.5 is a 1.5A low dropout linear regulator with a fixed 2.5V output. Its 0.55V dropout at full load enables efficient regulation from 3.3V rails. The DDPAK/TO-263-5 package provides excellent thermal performance. With 9 mA quiescent current, it balances power consumption and stability, making it ideal for DDR memory and low-voltage logic applications.
- 1.5A Output Current: Supports DDR memory and multiple logic devices on a single 2.5V rail.
- Low Dropout (0.55V @ 1.5A): Enables efficient conversion from 3.3V with minimal heat.
- Stable 2.5V Output: Meets tight voltage tolerances required by DDR and LVCMOS.
- TO-263-5 Package: Provides robust thermal management for industrial environments.
DDR Memory Termination
DDR SDRAM requires a 2.5V VDDQ supply. The LP3962ES-2.5 delivers 1.5A with low dropout, ideal for memory modules.
Low-Voltage Logic Power
For 2.5V logic families (LVCMOS), this regulator provides clean, stable power for high-speed digital circuits.
FPGA Core Auxiliary Rails
Some FPGAs use 2.5V for auxiliary circuits. The low dropout allows efficient conversion from 3.3V rails.
Networking Switches
Ethernet switches use 2.5V for PHY and MAC interfaces. The robust TO-263 package handles continuous load.
Industrial Controllers
PLCs with 2.5V analog-to-digital converters benefit from the low noise and stable output of this regulator.
Test Equipment
Signal generators and oscilloscopes use 2.5V references. The 9 mA quiescent current ensures minimal self-heating.
