The UM1530DA-18 is a fixed 1.8V LDO regulator delivering 300mA from a 6-DFN package. With an ultra-low 1.5µA quiescent current and 0.33V dropout at 200mA, it is optimized for battery-powered applications. Its 56dB PSRR provides clean power for sensitive electronics.
- Exceptional Battery Life: 1.5µA quiescent current is among the lowest in its class.
- High Efficiency: 0.33V dropout at 200mA reduces power dissipation.
- Miniature Size: 6-DFN (2x2mm) ideal for compact designs.
- Clean Output: 56dB PSRR at 100Hz minimizes noise interference.
