The Linear Technology LT3055EMSE-5#PBF is a fixed 5V low dropout linear regulator delivering 500mA. It features a low dropout voltage of 0.59V at full load and a quiescent current of just 130 μA. The 16-MSOP-EP package provides excellent thermal performance. With 66dB PSRR at 120Hz, it ensures clean power for sensitive analog and RF circuits.
- Low Dropout: 0.59V at 500mA allows operation from tight voltage margins.
- Low Quiescent Current: 130 μA reduces standby power in battery devices.
- Compact Thermal Package: MSOP-EP with exposed pad dissipates heat efficiently.
- Good PSRR: 66dB at 120Hz rejects mains noise for clean output.
