The LP3966ET-ADJ/NOPB is a high-performance adjustable LDO linear regulator from Texas Instruments, capable of delivering 3A of output current. Its output voltage can be set from 1.216V to 5.1V using external resistors, providing flexibility for a wide range of applications. With a dropout voltage of just 1.2V at full load, it efficiently regulates from higher input rails. The TO-220 package ensures excellent thermal performance for demanding industrial and telecom environments.
- High Current Capacity: Delivers up to 3A, suitable for power-hungry digital loads like FPGAs and processors.
- Adjustable Output: Voltage set from 1.216V to 5.1V, offering design flexibility across multiple rail requirements.
- Robust Thermal Package: TO-220 package dissipates heat effectively, ensuring reliability under continuous full-load operation.
- Low Dropout: 1.2V dropout at 3A allows operation with moderate input-to-output headroom, reducing power loss.
High-Current FPGA Core Supplies
The LP3966ET-ADJ/NOPB delivers up to 3A with an adjustable output down to 1.216V, making it ideal for powering FPGA core rails that require precise voltage scaling and high transient current capability.
DSP and Processor I/O Power
With its low dropout of 1.2V at 3A, this LDO can efficiently regulate 3.3V or 2.5V I/O supplies from a 5V bus, maintaining stable operation even during heavy digital switching.
Industrial Sensor Conditioning
The adjustable output allows fine-tuning of analog supply rails for sensor signal chains, while the 9 mA quiescent current ensures consistent performance in noisy industrial environments.
Telecom Line Cards
For telecom equipment requiring clean, low-noise power for mixed-signal components, the LP3966 provides a robust 3A solution with excellent line and load regulation.
Battery-Powered Test Equipment
Although quiescent current is moderate, the high current capability and adjustable output make it suitable for benchtop or portable test gear where precision outweighs battery life.
Automotive Infotainment Modules
The TO-220 package handles thermal stress well, and the adjustable output supports multiple voltage rails in infotainment systems, from 1.8V logic to 3.3V peripherals.
