The RT9198-18GY is a fixed-output low dropout linear regulator from Richtek, delivering a stable 1.8V rail at up to 300mA. Its low 130 μA quiescent current and 0.33V dropout voltage make it ideal for battery-powered and portable applications. The ultra-compact SC-82 package offers the smallest footprint solution for space-constrained designs, while high PSRR ensures clean power for noise-sensitive circuits.
- Ultra-Small SC-82 Package: Minimizes PCB footprint for the most space-constrained applications.
- Low Power Consumption: 130 μA quiescent current extends battery life in portable devices.
- High Noise Rejection: PSRR of 60dB to 30dB (100Hz-10kHz) provides clean output for sensitive circuits.
- Low Dropout Voltage: 0.33V at 300mA enables efficient operation near the output voltage.
Ultra-Compact Wearables
The tiny SC-82 package makes it ideal for smartwatches, fitness bands, and medical patches where PCB space is extremely limited.
Battery-Powered Remote Controls
Low 130 μA quiescent current extends battery life in remote controls, key fobs, and wireless presenters that spend most time in standby.
Noise-Sensitive Sensor Interfaces
High PSRR (60dB at 100Hz, 30dB at 10kHz) ensures clean power for temperature sensors, pressure sensors, and accelerometers in industrial IoT applications.
Low-Power Microcontrollers
The fixed 1.8V output is perfect for powering low-voltage MCUs in smart home devices, security systems, and environmental monitors.
Portable Test Equipment
The stable output and low dropout make it suitable for handheld multimeters, signal generators, and other portable test instruments.
Consumer Electronics Accessories
Ideal for earbuds, smart pens, and other small accessories requiring efficient 1.8V power regulation in a minimal footprint.
