The UM1530DB-25 is a 300mA low dropout regulator providing a fixed 2.5V output. With an ultra-low 1.5µA quiescent current and 0.33V dropout at 200mA, it excels in battery-powered designs. The 4-DFN (1x1mm) package saves board space while delivering 56dB PSRR at 100Hz for noise-sensitive applications.
- Ultra-Low Power: 1.5µA quiescent current extends battery life.
- Miniature Footprint: 4-DFN (1x1mm) ideal for space-constrained designs.
- Low Dropout: 0.33V at 200mA maximizes usable battery capacity.
- Good Ripple Rejection: 56dB at 100Hz for clean power rails.
