The LT3045EMSE#TRPBF is a high-performance linear regulator from Analog Devices, engineered for applications demanding ultra-low noise and exceptional power supply rejection. It delivers up to 500mA with a programmable output up to 15V, while maintaining a low 20µA quiescent current. Its 0.45V dropout voltage at full load ensures efficiency in tight voltage margin designs. The 12-MSOP-EP package provides excellent thermal dissipation, making it a versatile choice for precision instrumentation, RF systems, and battery-powered devices.
- Ultra-Low Noise Operation: 0.8µVrms output noise ensures clean power for sensitive analog and RF circuits.
- High PSRR (117dB at 120Hz): Effectively rejects input ripple, ideal for post-switching-regulator filtering.
- Low Quiescent Current (20µA): Maximizes battery life in portable and always-on applications.
- Programmable Output to 15V: Flexible voltage setting via external resistors for diverse design requirements.
