The LP3965ET-3.3/NOPB is a fixed 3.3V low dropout linear regulator from Texas Instruments, capable of delivering up to 1.5A of output current. With a low dropout voltage of just 0.55V at full load, it maintains a stable output even when the input supply is close to the output voltage. The TO-220-5 package provides excellent thermal dissipation for demanding applications. This regulator is ideal for post-regulation, battery-powered devices, and industrial systems requiring clean, reliable power.
- High Current Capacity: Delivers up to 1.5A, suitable for powering multiple ICs or high-power loads.
- Low Dropout Voltage: 0.55V at 1.5A ensures efficient operation with minimal headroom, extending battery life.
- Stable 3.3V Output: Fixed output simplifies design and ensures accuracy for logic and mixed-signal circuits.
- Robust TO-220 Package: Excellent thermal performance for continuous high-current operation.
High-Current 3.3V Rail Generation
Use the LP3965ET-3.3/NOPB to create a stable 3.3V rail from a 5V supply. Its 1.5A current capability and low 0.55V dropout make it ideal for powering FPGAs, microprocessors, and DSPs that require high current with minimal voltage loss.
Post-Regulation for Switching Converters
Place this LDO after a DC-DC converter to reduce output ripple and switching noise. The low quiescent current and high PSRR ensure clean, stable power for sensitive analog circuits like ADCs and PLLs.
Battery-Powered Equipment
In battery-operated devices, the 9 mA quiescent current helps extend runtime. The low dropout voltage allows the battery to discharge deeper before the regulator drops out, maximizing usable capacity.
Industrial Control Systems
With its TO-220 package and robust thermal performance, this regulator is suitable for industrial controllers, PLCs, and motor control boards that need reliable 3.3V logic power in harsh environments.
Networking and Telecom Infrastructure
Power line cards, routers, and base stations with a clean 3.3V supply. The high current capability supports multiple ICs, while the low dropout ensures stable operation during input voltage dips.
Audio and Precision Analog Circuits
Use this LDO to power op-amps, codecs, and audio DACs. The low noise and stable output reduce hum and distortion, improving audio signal integrity.
