The RT9198-1HGY from Richtek is a fixed 1.85V low dropout regulator capable of sourcing 300mA. With a low 130 μA quiescent current and a compact SC-82 package, it is designed for efficient power management in memory termination, portable audio, and low-voltage digital applications.
- Specialized Voltage: The 1.85V output is ideal for DDR termination and specific logic families.
- High Efficiency: Low dropout voltage (0.33V) reduces power dissipation.
- Miniature Package: SC-82 package saves valuable board space.
- Low Noise: Suitable for audio and precision analog circuits.
DDR Memory Bus Termination
The 1.85V output is specifically suited for DDR memory termination (VTT), providing the required current and stability.
Low-Voltage Digital Logic
Powers 1.8V-class logic ICs and microcontrollers that require a slightly higher voltage for optimal performance.
Portable Audio Players
Provides a clean, low-noise 1.85V supply for audio DACs and amplifiers, improving sound quality.
Wireless Sensor Networks
The low quiescent current extends battery life in remote sensor nodes that operate at 1.85V logic levels.
Embedded Systems
Ideal for powering the I/O ring of embedded processors that need a 1.85V rail separate from the core.
Test and Measurement Equipment
Offers a stable reference voltage for calibration circuits in portable test instruments.
