The UM1530DA-38 is a fixed 3.8V LDO linear regulator delivering 300mA from a compact 6-DFN package. With an ultra-low 1.5µA quiescent current and 0.33V dropout at 200mA, it maximizes efficiency in battery-powered designs. Its 56dB PSRR at 100Hz ensures clean output for sensitive analog and RF circuits.
- Extended Battery Life: 1.5µA quiescent current minimizes standby drain in portable devices.
- Stable Output Under Load: 0.33V dropout at 200mA maintains regulation as input voltage approaches output.
- Space-Saving Design: 6-DFN (2x2mm) package reduces PCB footprint for compact products.
- Clean Power Delivery: 56dB PSRR at 100Hz filters supply noise for sensitive electronics.
Battery-Powered IoT Sensors
The 1.5µA quiescent current extends battery life in always-on sensor nodes, while the 3.8V fixed output suits Li-ion direct connections.
Portable Medical Devices
Low dropout of 0.33V ensures stable 3.8V rail even as battery voltage sags, critical for consistent diagnostic readings.
