The LM1085R-ADJ is a robust 3A low dropout linear regulator from TAEJIN, offering an adjustable output voltage from 1.25V to 15V. Its low 1.5V dropout at full load and excellent 65dB ripple rejection ensure a clean, stable power supply for demanding applications. Housed in a TO-263-3 package, it is designed for high-current systems requiring minimal heat dissipation and reliable performance.
- High Current Capacity: Delivers up to 3A, suitable for power-hungry digital cores and peripherals.
- Adjustable Output Flexibility: Output can be set from 1.25V to 15V with external resistors, covering a wide range of logic and analog voltages.
- Low Quiescent Current: 90 µA quiescent current improves efficiency in always-on and battery-operated systems.
- Excellent Ripple Rejection: 65dB PSRR at 120Hz filters out mains-related noise for cleaner output.
High-Current FPGA and DSP Core Supplies
The 3A output capability and adjustable voltage down to 1.25V make it ideal for powering the core logic of FPGAs and DSPs that require precise, low-voltage, high-current rails.
Battery-Powered Industrial Equipment
