Overview
Description
The LT3045EDD#TRPBF is a high-performance, ultralow-noise, ultrahigh-PSRR linear low-dropout (LDO) regulator designed by Analog Devices. It is specifically tailored for applications requiring precise voltage regulation and minimal noise, such as in sensitive analog and RF environments. The device offers a wide input voltage range and can provide up to 500 mA of output current with excellent transient response.
Key features include a very low output noise of 0.8 µVRMS (10 Hz to 100 kHz) and a high power supply rejection ratio (PSRR) of up to 79 dB at 1 MHz, making it highly effective in filtering out input supply noise. The LT3045 also incorporates a precision current reference, which facilitates easy parallel operation for higher current requirements. Other features include programmable current limit, fast start-up, and thermal protection.
The device is housed in a compact, thermally enhanced 10-lead DFN package, making it suitable for space-constrained applications. Its robustness and performance make it ideal for powering critical components in communication, instrumentation, and medical devices.
