.The LTC7103EUHE#PBF is an advanced switching voltage regulator with fast current programming and low-EMI (electromagnetic interference) technology from Analog Devices. It is a synchronous step-down regulator with an input voltage range from 4.5 to 105V and a nominal output of 2.3A. The device operates over an extremely wide temperature range of -40°C to +125°C. It features current-mode controls for excellent transient response and offers a no-load shutdown current of 3.5µA that can be reduced to 65nA when operating in the regular shutdown mode. It also has pulse-width modulation (PWM) mode for exceptional load transient response and supports light load efficiency and power savings. Additionally, it includes a resistor adjustable output voltage, multiple frequency operation, and programmable current limit.This voltage regulator integrates several adevantages such as low EMI, excellent load and line regulation, fast current programming, no-load shutdown current adjustment, and low quiescent current for improved efficiency. It is highly recommended for automotive, high-efficiency industrial, and battery-powered applications.
