The S-T111B50MC-OHJTFG is a linear voltage regulator from the electrical component vendor Toshiba. It is a PMIC (Power Management IC) intended for voltage regulation and comes in a TO-220AB package, making it suitable for a variety of applications. The device is designed to provide a regulated output voltage of 5V with a maximum load current of 1.5A, and can operate over a wide input voltage range. The device is suitable for applications such as LED lighting and DC/DC converters.

The S-T111B50MC-OHJTFG is a single output, fixed output voltage regulator with a dropout voltage of 1.4V. The device is designed for use in applications such as battery-powered devices and SMPS circuits. It is capable of delivering a regulated output voltage with a maximum current of 1.5A. The over-voltage protection feature keeps the output voltage below a predefined limit and limits the current in case of over-voltage. The device also features a thermal shutdown protection which prevents it from overheating in case of an overload.

The S-T111B50MC-OHJTFG is also designed to provide a reliable and efficient operation. It is designed to reduce susceptibility to EMI, spikes and transients. Its low-noise design and high PSRR makes it suitable for use in noise sensitive applications. The device also features a wide range of protection features such as Over-voltage protection,Thermal Shutdown, Short-circuit protection, and Reverse Current protection.

The S-T111B50MC-OHJTFG works on the principle of linear regulation. A linear regulator essentially acts as a voltage divider and uses a voltage reference, such as a zener diode, to maintain the output voltage at a predetermined value regardless of load or input voltage. The linear regulator utilizes two transistors, one to regulate the output voltage and the other to control the current flow, essentially acting as an on/off switch.

The device also features differential remote sense which allows the output voltage to be adjusted to compensate for any losses along the power supply trace. This, in turn, helps to maintain an accurate output voltage across the entire trace.The S-T111B50MC-OHJTFG is designed to provide high-performance and reliable operation, making it ideal for a range of applications. It is a low-cost and efficient solution for voltage regulation in LED lighting, DC/DC converters, battery-powered devices, and SMPS circuits.
