The LP3892EMR-1.2/NOPB from National Semiconductor is a fixed 1.2V LDO regulator delivering up to 1.5A with an ultra-low dropout of 0.55V. Its 30 µA quiescent current and high PSRR (80dB at 120Hz) make it ideal for powering FPGAs, DSPs, and other noise-sensitive digital loads. The 8-SO PowerPad package ensures efficient heat dissipation.
- Ultra-Low Dropout: 0.55V at 1.5A maximizes efficiency in low-voltage systems.
- High PSRR: 80dB at 120Hz effectively filters rectified AC ripple, providing clean DC power.
- Low Quiescent Current: 30 µA reduces standby power consumption in battery-operated devices.
- PowerPad Package: Enhanced thermal performance for sustained 1.5A output.
FPGA Core Power Supply
The 1.2V fixed output and 1.5A capability are ideal for FPGA core rails, while 80dB PSRR at 120Hz ensures stable operation during dynamic load changes.
DSP and Microprocessor Power
Low dropout of 0.55V at 1.5A allows efficient conversion from 1.8V rails, minimizing power loss in battery-powered portable devices.
Networking Equipment
With 65dB PSRR at 1kHz, this regulator reduces switching noise in routers and switches, ensuring reliable 1.2V logic supply.
Industrial Automation Controllers
The 8-SO PowerPad package provides excellent thermal dissipation for continuous 1.5A operation in 24V industrial environments.
Consumer Electronics
30 µA quiescent current extends standby time in smart TVs and set-top boxes, while 1.2V rail powers HDMI and USB controllers.
Automotive Infotainment
Stable 1.2V output with high PSRR supports audio DSPs and display drivers, reducing audible noise and visual artifacts.
