LT3045EMSE#PBF Ultra-Low Noise, High PSRR LDO Voltage Regulator
The LT3045EMSE#PBF is a high-performance, low-dropout (LDO) linear voltage regulator from Analog Devices, designed for applications requiring ultra-low noise, high power supply rejection ratio (PSRR), and precise voltage regulation. It features an advanced architecture with a precision current-source reference followed by a high-performance voltage buffer, delivering exceptional line and load regulation. The device operates with an input voltage range of 1.8V to 20V and provides a fixed or adjustable output voltage from 0V to 15V, making it highly versatile for a wide range of power supply designs.
A standout feature of the LT3045EMSE#PBF is its ultra-low output noise of just 0.8µVRMS (10Hz to 100kHz), making it ideal for sensitive analog and RF circuits, such as precision instrumentation, data converters, and high-speed communication systems. Additionally, it offers an outstanding PSRR of up to 79dB at 1MHz, ensuring stable operation even in noisy power environments. The regulator supports a 500mA output current with excellent thermal performance, thanks to its MSOP-12 exposed pad package, which enhances heat dissipation.
The LT3045EMSE#PBF includes multiple protection features, such as current limit, thermal shutdown, and reverse-battery protection, ensuring robust operation in demanding conditions. It also provides a programmable current limit and a power-good flag for system monitoring. The device’s low dropout voltage (typically 300mV at full load) improves efficiency in low-voltage applications. Its fast transient response and minimal output capacitance requirements (as low as 10µF) simplify PCB design while maintaining stability.
