The LT1764AEFE-2.5#PBF from Analog Devices is a series of low-dropout voltage (LDO) regulators with a wide input voltage range and fast transient response. It has an ultra-low output noise profile and low dropout voltage, making it ideal for powering low-voltage microprocessors, DSPs, and other AI applications. It offers output voltages from 0.8 V to 5 V, adjustable output current up to 3 A, and low-dropout performance down to 0.5 V. It also features thermal shutdown for protection against overloads and short-circuits, and improved input/output isolation to prevent ground loops. Additionally, the LT1764AEFE-2.5#PBF has an adjustable soft-start function for power sequencing and delayed startup. It is packaged in a PBF package.
