The LT1587CT-3.45#PBF is a high-performance, low-dropout (LDO) voltage regulator manufactured by Analog Devices. It features a fixed 3.45-volt output, and has a high-side current limit of 3 Amps. The device is suitable for applications with input voltages ranging from 2.5V to 40V, and is capable of delivering a clean and regulated output voltage with excellent line and load regulation. With its small surface-mount package, it is ideal for board-space-limited designs, as well as for applications with stringent noise, output voltage, accuracy, and transient requirements.
