The RT9078 is a fixed 3.3V LDO regulator from Richtek, offering 300mA output current. It features an ultra-low quiescent current of 4 µA and a dropout voltage of 0.22V at full load. The TSOT-23-5 package is suitable for compact, power-sensitive designs.
- Ultra-Low IQ: 4 µA quiescent current dramatically extends battery life.
- High PSRR: 75dB at 1kHz ensures clean output for RF and analog circuits.
- Higher Current: 300mA output supports more demanding loads.
- Small Package: TSOT-23-5 minimizes board space.
Wearable Devices
The ultra-low 4 µA quiescent current makes the RT9078 perfect for wearables where battery life is critical.
Energy Harvesting Systems
With 75dB PSRR at 1kHz and low dropout, it efficiently regulates harvested energy for microcontrollers.
Portable Medical Monitors
Provides clean 3.3V power for sensitive medical sensors, with high PSRR to reject interference.
Wireless Transceivers
300mA output supports RF modules, while low quiescent current preserves battery in standby mode.
Smart Home Sensors
Ideal for always-on sensors that need minimal power draw and stable voltage.
