ST1L05BPUR Integrated Circuits (ICs)

ST1L05BPUR is an adjustable linear voltage regulator. It is of low power type, with power dissipation of up to 5W and maximum output current of 1.5A. This device works on enabled pin control logic, allowing for better regulation and better control of power supply. ST1L05BPUR has a wide input voltage range and comes with a low dropout voltage.

ST1L05BPUR is mainly used in portable electronic devices such as smartphones and tablets. It is also used in automotive and industrial applications, where power regulation and component size are of paramount importance. The device is designed to provide an accurate regulated output voltage in a small, efficient package with low power dissipation.

ST1L05BPUR is a three-terminal regulator with a voltage reference, an enabling pin and an output voltge control. It is enabled through the enabled pin through a logic signal of high or low. When the device is enabled, the output control sets the output voltage to the required level. The voltage reference ensures that the output voltage is maintained irrespective of the line, load and temperature variations.

The circuit inside the ST1L05BPUR comprises of two internal PNP transistors and a Zener diode. The two PNP transistors act as drivers, controlling the voltage at the output. The Zener diode ensures that the output voltage is not raised beyond its specified maximum level. The transistors and the Zener diode are connected in such a way that the output is regulated to provide the desired voltage, regardless of the line, load or temperature variations.

ST1L05BPUR provides superior temperature stability , high accuracy and low noise output. It has two internal short circuit protection features—thermal shutdown and current limit. Thermal Shutdown prevents the device from being damaged by high temperatures, while current limit prevents the device from supplying too much current. It also features a soft-start function to reduce inrush current, making it highly efficient.

ST1L05BPUR is a highly efficient and reliable linear voltage regulator. Its small size and low power dissipation makes it ideal for use in portable electronic devices. It offers thermal, current and over-voltage protection to ensure safe operation. ST1L05BPUR is suitable for use in automotive and industrial applications where power regulation and component size are of paramount importance.
