The L123CB from STMicroelectronics is a monolithic integrated programmable voltage regulator designed for high precision applications. It supports an adjustable output voltage ranging from 2V to 37V and can deliver an output current of up to 150mA without the need for an external pass transistor. The device features internal current limiting, which can be adjusted, and provisions for remote shut-down.
This voltage regulator is available in two package types: a 10-lead Metal Can (TO-100) and a 14-lead dual in-line plastic package (DIP). It can operate with positive or negative supply voltages and can be configured for series, shunt, switching, or floating operation. Key electrical characteristics include low line and load regulation, good ripple rejection, and a low quiescent current.
The operating junction temperature range for the L123CB varies by specific variant, with one version rated from -25°C to 150°C and another from 0°C to 70°C. The absolute maximum input voltage is 40V, and the device offers adjustable current limiting for protection.
