The RT9198-15GU5 is a fixed-output low dropout linear regulator from Richtek, delivering a stable 1.5V rail at up to 300mA. Its low 130 μA quiescent current and 0.33V dropout voltage make it well-suited for battery-powered and portable applications. The SC-70-5 package offers a compact solution for space-constrained designs, while the high PSRR ensures clean power for noise-sensitive circuits.
- Extended Battery Life: Ultra-low 130 μA quiescent current minimizes standby power consumption in portable devices.
- Clean Power Delivery: PSRR of 60dB to 30dB (100Hz-10kHz) suppresses supply noise for sensitive analog and RF circuits.
- Efficient Low-Dropout Operation: 0.33V dropout at 300mA allows operation close to the output voltage, maximizing efficiency.
- Compact Footprint: SC-70-5 package saves PCB space for miniaturized electronic designs.
Portable Battery-Powered Devices
The low 130 μA quiescent current and 300mA output make it ideal for extending battery life in wearables, remote controls, and portable sensors where standby power consumption is critical.
Noise-Sensitive Analog Circuits
With PSRR of 60dB at 100Hz and 30dB at 10kHz, this regulator effectively filters power supply noise for precision analog front-ends, audio codecs, and sensor signal conditioning circuits.
Low-Voltage Digital Core Supplies
The fixed 1.5V output is suitable for powering low-voltage digital cores in MCUs, DSPs, and FPGAs that require a stable, clean supply rail up to 300mA.
Space-Constrained PCB Designs
The compact SC-70-5 package minimizes board footprint, making it suitable for dense designs in IoT modules, smart cards, and miniaturized medical devices.
RF and Wireless Modules
The high PSRR across a wide frequency range helps maintain signal integrity in RF transceivers, Bluetooth modules, and Zigbee radios by reducing supply-coupled interference.
Battery-Operated Instrumentation
The combination of low dropout (0.33V) and low quiescent current ensures efficient operation even as the battery voltage approaches the output level, maximizing usable battery capacity.
