The LP3965ESX-1.8/NOPB is a 1.5A low dropout linear regulator from Texas Instruments, delivering a fixed 1.8V output. Its low dropout voltage of 0.55V at full load enables efficient conversion from 2.5V or 3.3V rails. The TO-263 (DDPAK-5) package provides excellent thermal dissipation. With a quiescent current of 9 mA, it ensures fast transient response, making it ideal for powering low-voltage digital cores, memory, and mixed-signal circuits.
- Efficient Low-Voltage Conversion: 0.55V dropout allows 2.5V to 1.8V conversion with minimal heat.
- High Current for Digital Loads: 1.5A capacity supports modern processors and FPGAs.
- Thermally Efficient Package: TO-263 with exposed pad ensures reliable operation at full load.
- Fast Transient Response: 9 mA quiescent current provides quick recovery from load steps.
Low-Voltage Digital Cores
Ideal for powering 1.8V logic cores in FPGAs, ASICs, and microcontrollers that require high current with low noise.
DDR Memory Termination
Provides a stable 1.8V rail for DDR2/DDR3 memory VDDQ and termination circuits.
Post-Regulation from 2.5V
With 0.55V dropout, it can efficiently step down from a 2.5V rail to 1.8V with minimal loss.
Portable Electronics
Low dropout extends battery life in smartphones, tablets, and wearables that use 1.8V I/O rails.
Optical Transceivers
Clean 1.8V supply for SFP and QSFP modules, ensuring stable operation of laser drivers and control ICs.
Industrial Automation
Reliable 1.8V for sensors and PLCs, with thermal protection for harsh environments.
