The Texas Instruments LM1084IT-5.0/NOPB is a high-current 5A low dropout linear regulator providing a fixed 5.0V output. Packaged in a TO-220-3 through-hole case, it offers a dropout voltage of 1.5V at full load and a quiescent current of 10mA. With 68dB PSRR at 120Hz, it delivers clean, stable power for demanding digital and analog applications.
- High 5A Output: Powers multiple ICs, relays, or peripheral devices from a single regulator.
- TO-220 Package: Excellent thermal performance with a metal tab for heatsink attachment.
- Low Dropout: 1.5V dropout minimizes power loss, improving efficiency in 5V systems.
- Robust Protection: Internal current limiting and thermal shutdown ensure safe operation.
High-Current 5V Logic Supplies
For systems with multiple TTL or CMOS logic ICs, the LM1084IT-5.0/NOPB provides a robust 5A supply. The TO-220 package with a metal tab allows easy heatsinking for continuous high-current operation.
Post-Regulation for 5V Bus
When a switching regulator generates a noisy 5V rail, this LDO cleans it up. With 68dB PSRR at 120Hz, it attenuates ripple and switching spikes, ensuring reliable operation of sensitive digital circuits.
Industrial Actuator Control
In PLCs and motor control systems, 5V is often needed for control logic. The 5A capability can power multiple I/O modules, while thermal shutdown protects against overloads.
Battery Charging Stations
For charging 5V USB devices or battery packs, this regulator can supply up to 5A. The low dropout ensures efficient charging even with a slightly depleted input battery.
Audio Power Amplifiers
Some audio preamplifiers and headphone amps require a clean 5V rail. The high current capability and 68dB PSRR reduce hum and distortion, improving sound quality.
Test and Measurement Equipment
Benchtop instruments often need a stable 5V reference for ADC/DAC circuits. The LM1084IT-5.0/NOPB provides the current headroom and low noise required for accurate measurements.
