The RT9198-25GU5 from Richtek is a fixed 2.5V low dropout linear regulator capable of delivering 300mA. Its ultra-low quiescent current of 130 μA and high PSRR make it ideal for battery-operated and noise-sensitive applications. Housed in a compact SC-70-5 package, it offers a dropout voltage of just 0.33V at full load, ensuring efficient operation even with tight headroom.
- Extended Battery Life: Ultra-low 130 μA quiescent current minimizes standby power consumption.
- Clean Output: High PSRR (60dB at 100Hz) rejects input ripple for stable analog supplies.
- Low Dropout: 0.33V dropout at 300mA allows operation from nearly depleted batteries.
- Compact Footprint: SC-70-5 package saves board space in portable designs.
Portable Battery-Powered Devices
The low 130 μA quiescent current extends battery life in wearables, remote sensors, and handheld instruments where standby power is critical.
Noise-Sensitive Analog Circuits
With PSRR of 60dB at 100Hz and 30dB at 10kHz, this LDO effectively filters supply ripple for precision op-amps, ADCs, and audio codecs.
RF and Wireless Modules
Stable 2.5V output with low dropout ensures consistent performance for Bluetooth, Zigbee, and sub-GHz transceivers even as battery voltage sags.
Microcontroller Power Rails
Provides clean, regulated 2.5V for MCU I/O and core logic, reducing noise-induced errors and improving system reliability.
Compact Sensor Interfaces
The SC-70-5 package fits space-constrained designs, delivering stable power to MEMS sensors and signal conditioning circuits.
Industrial Control Loops
Fast transient response and low dropout maintain regulation in actuator and motor control circuits powered from unregulated supplies.
