The RT9198-33GJ5R is a fixed 3.3V LDO regulator from Richtek, delivering 300mA with a dropout of only 0.33V. Its 130 μA quiescent current is optimized for battery-powered applications. The device features excellent PSRR (60dB at 100Hz), making it suitable for noise-sensitive circuits. Packaged in a space-saving TSOT-23-5, it balances performance with a minimal footprint.
- Space-Efficient Design: TSOT-23-5 package is 30% smaller than standard SOT-23, ideal for miniaturized PCBs.
- Low Power Consumption: 130 μA quiescent current extends battery runtime in always-on devices.
- Superior Ripple Rejection: 60dB PSRR at 100Hz ensures clean power for analog and RF circuits.
- Reliable Low Dropout: 0.33V dropout at full load allows operation from low-voltage sources.
Compact Wearable Electronics
The TSOT-23-5 package is ideal for fitness trackers and smartwatches where board space is at a premium, while the 130 μA quiescent current preserves battery life.
Portable Medical Devices
Stable 3.3V output with low noise characteristics supports glucose monitors and pulse oximeters requiring consistent power for accurate readings.
IoT Edge Nodes
For wireless sensors and beacons, the low dropout voltage ensures reliable operation from lithium coin cells down to their end-of-life voltage.
Audio Processing Equipment
High PSRR at low frequencies (60dB at 100Hz) reduces hum and ripple from switching power supplies in portable audio DACs and headphone amps.
Automotive Interior Electronics
Though not AEC-Q100 qualified, the robust design suits infotainment and dashboard clusters where clean 3.3V rails are needed for display drivers.
FPGA and CPLD Core Supplies
Provides a dedicated 3.3V rail for I/O banks and auxiliary logic, ensuring stable operation during high-speed switching.
