- 50mA output current with 0.02% line regulation delivers stable, accurate voltage for sensitive analog and digital circuits in portable devices
- Compact 5-pin SOT-23 package with fixed output simplifies design and minimizes PCB footprint for space-constrained battery-powered applications
Applications
The TPS77050DBVTG4 is designed for ultra-low-power portable electronics, IoT devices, and battery-operated systems requiring a stable regulated supply from a 5V to 10V input with minimal power loss. Its extremely low dropout voltage makes it ideal as a post-regulator following switching converters in RF modules, precision sensors, and microcontroller power rails where low ripple and high accuracy are essential. It is also used in handheld test instruments, GPS receivers, and always-on sensor nodes where minimizing quiescent current and dropout loss directly extends battery life.
