Подробное описание 103AIW
Product Overview
103AIW is commonly associated with STMicroelectronics TSM103AIW / TSM103W series devices, where 103AIW is often used as a top marking or shortened marking-style reference. The device is a monolithic IC that combines operational amplifier functions with an internal 2.5V voltage reference, providing a compact solution for power supply control, feedback regulation and monitoring circuits. With wide supply voltage operation, low input offset voltage, low supply current, medium bandwidth and SO-8 / wide SO package options depending on the exact ordering code, it is suitable for battery chargers, AC-DC adapters, SMPS feedback circuits, power management boards, data acquisition systems and legacy power supply repair applications.
