The RT9198-25GJ5R is a low dropout linear regulator from Richtek, offering a fixed 2.5V output with up to 300mA of current. Its low 130µA quiescent current and 0.33V dropout at full load make it an efficient choice for battery-powered and noise-sensitive applications. The TSOT-23-5 package is compact for space-constrained designs, while the PSRR of 60dB at 100Hz ensures clean power delivery.
- Extended Battery Life: Ultra-low 130µA quiescent current minimizes standby power consumption in portable devices.
- Clean Output: PSRR of 60dB at 100Hz and 30dB at 10kHz suppresses input ripple for sensitive analog loads.
- Low Dropout: 0.33V dropout at 300mA allows operation from a 2.8V rail with minimal headroom.
- Compact Footprint: TSOT-23-5 package saves PCB space for miniaturized designs.
Portable Battery-Powered Devices
The low 130µA quiescent current and 2.5V fixed output make it ideal for extending battery life in wearables, remote controls, and portable medical devices where standby power is critical.
Noise-Sensitive Analog Circuits
With PSRR of 60dB at 100Hz and 30dB at 10kHz, this LDO effectively filters power supply ripple, ensuring clean power for precision sensors, op-amps, and audio codecs.
