The Texas Instruments LP3965ET-ADJ/NOPB is a versatile adjustable low dropout linear regulator capable of delivering up to 1.5A. With a reference voltage of 1.216V, the output can be set from that level up to the input voltage minus dropout. It features a low dropout of 0.55V at full load and a PSRR of 60dB at 120Hz, ensuring clean power. The TO-220-5 package provides excellent thermal performance for high-current applications.
- Adjustable Output: Set any voltage from 1.216V up, providing flexibility for various digital and analog rails.
- High Current: 1.5A output capability supports power-hungry FPGAs, processors, and multiple ICs.
- Low Dropout: 0.55V at 1.5A minimizes power loss and heat generation, improving system efficiency.
- Good Ripple Rejection: 60dB PSRR at 120Hz filters mains-related noise, ideal for audio and precision analog circuits.
Adjustable Core Voltage for FPGAs
The adjustable output (down to 1.216V reference) allows precise setting of FPGA core voltages (e.g., 1.2V, 1.8V) with 1.5A capability, meeting the tight tolerance requirements of modern digital logic.
High-Current 3.3V Rail
Set the output to 3.3V with external resistors to power multiple digital ICs, where the 1.5A current capacity and 0.55V dropout ensure stable operation from a 5V supply.
Post-Regulation for Switching Supplies
Use after a DC-DC converter to provide a low-noise, precisely adjustable output for sensitive analog circuits, leveraging the LDO's PSRR of 60dB at 120Hz.
Battery Charger Reference
In battery charging circuits, the adjustable output can be set to the exact float voltage required for Li-Ion or lead-acid batteries, with 1.5A handling charge currents.
Audio Power Supply
Create a clean, adjustable supply rail for audio preamplifiers and DACs, where the low dropout and high PSRR minimize hum and noise from the main supply.
Industrial Sensor Excitation
Provide a precise, adjustable excitation voltage for bridge sensors and transducers, ensuring accurate measurements with the 1.5A drive capability.
