The RT9080N-08GJ5 is a high-performance low dropout linear regulator from Richtek, delivering a fixed 0.8V output with up to 600mA of current. Its ultra-low 4 µA quiescent current and 75dB PSRR at 1kHz make it ideal for battery-powered and noise-sensitive applications. Housed in a compact TSOT-23-5 package, this LDO offers a dropout voltage of just 1.33V at full load, ensuring efficient operation even with low input margins.
- Extended Battery Life: Ultra-low 4 µA quiescent current minimizes standby power consumption in portable devices.
- Clean Power Delivery: 75dB PSRR at 1kHz effectively suppresses input ripple, ensuring stable output for sensitive analog circuits.
- High Current Capability: 600mA output supports a wide range of loads, from microcontrollers to RF transceivers.
- Compact Footprint: TSOT-23-5 package saves PCB space without compromising thermal performance.
Battery-Powered IoT Sensors
The ultra-low 4 µA quiescent current extends battery life in always-on sensor nodes, while the 600mA output supports periodic wireless transmissions.
FPGA Core Voltage Supply
Modern FPGAs require precise 0.8V core rails. The RT9080N-08GJ5 delivers stable 0.8V with 75dB PSRR at 1kHz, filtering switching noise from upstream DC-DC converters.
Portable Medical Devices
Low dropout of 1.33V at full load allows operation from a single Li-ion cell down to 2.1V, ensuring reliable performance in compact diagnostic tools.
Wearable Electronics
The TSOT-23-5 package (2.9mm x 1.6mm) fits space-constrained wearables, and the 4 µA ground current minimizes parasitic drain on tiny coin-cell batteries.
Noise-Sensitive Audio Codecs
With 75dB PSRR at 1kHz, this LDO attenuates power supply ripple, preserving audio signal integrity in portable media players and smart speakers.
Automotive ECU Auxiliary Rails
Although not AEC-Q100 qualified, the wide input tolerance and thermal protection make it suitable for non-critical auxiliary 0.8V rails in aftermarket automotive electronics.
