The LP3966ESX-1.8/NOPB is a 3A low-dropout linear regulator from Texas Instruments with a fixed 1.8V output. Packaged in TO-263 (DDPAK-5), it offers a dropout voltage of 1.2V at full load and a quiescent current of 9mA. This regulator is well-suited for post-regulation and noise-sensitive applications requiring high current and stable voltage.
- High Output Current: 3A capability for power-hungry digital and analog loads.
- Simple Post-Regulation: 1.2V dropout enables easy cascading after 3.3V switchers.
- Low Quiescent Current: 9mA IQ reduces power loss in always-on systems.
- Durable Package: TO-263 ensures excellent heat dissipation for reliable operation.
Post-Regulation for DC-DC Converters
The 1.2V dropout allows use after a 3.3V switching regulator to produce a clean 1.8V rail with reduced switching noise.
Audio Amplifier Supplies
Provides low-noise 1.8V for digital audio codecs and DACs, with 9mA quiescent current for efficient operation.
Server Motherboard VRMs
Supports 3A loads for memory termination or I/O logic in server platforms, with robust TO-263 thermal performance.
Test and Measurement Equipment
