The LM1084R-ADJ from TAEJIN is a high-current 5A adjustable low dropout linear regulator. The output voltage can be set from 1.25V to 15V using two external resistors. With a dropout voltage of 1.5V at full load and 65dB PSRR at 120Hz, it delivers clean, stable power for a wide range of applications. The TO-263-3 package provides excellent thermal performance.
- Adjustable Output (1.25V to 15V): Provides design flexibility for various voltage requirements without changing components.
- High 5A Output Current: Supports demanding loads, from logic circuits to power amplifiers.
- Low Dropout (1.5V @ 5A): Reduces power dissipation and allows operation from lower input voltages.
- Excellent PSRR (65dB @ 120Hz): Filters out mains ripple and low-frequency noise for clean power delivery.
Adjustable Bench Power Supplies
Provides a versatile 1.25V to 15V output for lab equipment. The 5A current capability supports a wide range of loads, from logic circuits to small motors.
Variable Voltage for Audio Circuits
Allows precise setting of supply voltage for op-amps and audio preamps. The 65dB PSRR at 120Hz ensures hum-free operation.
Battery Charger Circuits
Set the output voltage to match battery chemistry (e.g., 4.2V for Li-ion, 14.4V for lead-acid). The 5A capability supports fast charging.
FPGA and DSP Core Supplies
Adjust the output to match the exact core voltage required by the processor (e.g., 1.8V, 2.5V, 3.3V). The high current handles transient loads.
Custom Power Rails for Prototyping
Ideal for development boards where multiple voltage levels are needed. The adjustable output eliminates the need for multiple fixed regulators.
Industrial Sensor Interfaces
Provides a precise, adjustable supply for analog sensors and transducers. The low dropout ensures stable operation from unregulated input sources.
