PMIC (Power Management ICs) is a combination of integrated circuits that allow for efficient management of power by providing regulated output voltage and precise current feed to numerous peripheral components in a device. Voltage Regulator ICs are parts of the PMIC family and are used to provide a steady and reliable output supply to any load despite changes in input voltage and current. The L78L08ABD13TR is a Linear Voltage Regulator IC from STMicroelectronics, specifically designed for applications requiring higher output current.

Features

The L78L08ABD13TR is a precisely designed Linear Voltage Regulator, with a wide input voltage range of up to 35V and an output current of up to 80mA. It has an IO-pin shutdown feature, allowing the user to control the function of the board from the user-programmable input to the IO port. It is also equipped with built-in short circuit protection and thermal overload protection for safe operation.

Applications

Typical applications of the L78L08ABD13TR include portable applications such as powering of portable radios, laptop PCs, gaming consoles, and cellular phones. It is also suitable for use in computers and peripherals such as printers, scanners, and modems. Additionally, the L78L08ABD13TR can be utilized in medical devices, industrial equipment, and audio-visual systems.

Working Principle

The L78L08ABD13TR has an input voltage range of up to 35V, with a maximum output current of 80mA. It follows a linear topology for output regulation, implementing a high gain on-chip series pass regulator. Its operation is based on the principle of Ohm’s law, where the output voltage is directly proportional to the difference of the input voltage and the load resistance.

As the output voltage regulation is provided by a series pass regulator, it will have a limited bandwidth of its response time. Furthermore, an inherent output voltage droop is observed due to the finite input impedance of the series pass element, but this should not be of concern as there is no dynamic load in the output.

In order to reduce power dissipation, the L78L08ABD13TR includes a power supply-ON/OFF switch
