The LT3065HDD-3.3 is a 500mA low dropout linear regulator delivering a fixed 3.3V output. It features a low 510mV dropout at full load and a quiescent current of just 110µA, making it ideal for battery-powered and noise-sensitive applications. With 71dB PSRR at 120Hz, it effectively rejects input ripple. The compact 10-DFN (3x3) package suits space-constrained designs.
- Extended Battery Life: Ultra-low 110µA quiescent current minimizes standby power consumption in portable devices.
- Clean Output: 71dB PSRR at 120Hz filters supply noise, ensuring stable performance for sensitive analog circuits.
- High Efficiency at Low Dropout: 510mV dropout at 500mA allows operation from marginally higher input rails, reducing power dissipation.
- Compact Footprint: 10-DFN (3x3) package saves board space for dense PCB layouts.
