Description
L146CB is a monolithic integrated programmable voltage regulator in 14 lead dual in-line plastic package and 10 lead Metal Can (TO-100 type). It is made with high voltage technology and provides internal current limiting and thermal shut down protection, when current exceeds 150 mA an external NPN or PNP pass element may be used. Provisions are made for adjustable current limiting and remote shut down. The L146CB is intended to widen the application range of L123 up to 80V.
A monolithic integrated programmable voltage regulator refers to an integrated circuit (IC) that combines the functions of a voltage regulator with programmability features. It provides a regulated output voltage while allowing the user to adjust or program specific voltage levels according to their requirements.[…]
Monolithic integrated programmable voltage regulators find applications in various electronic systems, including power supplies, battery charging circuits, embedded systems, telecommunications equipment, and portable devices. Their programmability allows for flexibility in adapting to different voltage requirements and system configurations.
