L78L15ABD is a low-dropout linear voltage regulator with the maximum output current capability of 1.5 A, acting as a drop-in replacement for dated T0-220 and TO-3-type regulators. This three-terminal regulator is designed to offer superior power supply rejection, low quiescent current, thermal-shutdown and current-limiting protection. The voltage regulator is built on a custom-made integrated circuit and is available in the TO-252, SOT-89 and SOIC package type.

The L78L15ABD device is suitable for voltage regulation and current-limiting in automotive and industrial applications, as well as in other applications where size is a significant factor. It has an adjustable voltage range of 1.2 V to 35 V with an output current of 1.5 A. It comes with a guaranteed output voltage of 0.01%/V (at 10 A) load regulation and 0.1%/V line regulation.

The working principle of the L78L15ABD digital linear voltage regulator is based on a current-limiting architecture with an internal pass element and is controlled by an internal error amplifier with a low voltage offset and internal level-shifting circuitry. The pass element, which is the current-limiting element, is designed to consume almost no power at light load, leading to better power efficiency. The internal structure has complete protection for thermal shutdown and current-limiting, and it can also be used for open-loop regulation, such as ripple rejection applications.

The L78L15ABD linear voltage regulator has an input voltage range of 1.2V to 35V, an adjustable output voltage range from 1.2V to 35V, a current limit of 1.5 A, a minimum dropout voltage of 0.2 V, a typical quiescent current of 4 mA and a thermal resistance of 1.1 degree C/W. It also features superior power supply rejection, low quiescent current and thermal-shutdown and current-limiting protection.

The device provides high precision output voltage regulation and low output voltage deviations. The maximum output current capability is 1.5A, making it ideal for medium power applications. The L78L15ABD has short-circuit protection, which limits the output current to prevent damage to the device and other components connected to it. It has an adjustable voltage range of 1.2V to 35V with an output current of 1.5A and a maximum dropout voltage of 0.2V.

The L78L15ABD is ideal for automotive and industrial applications, where the size of the regulator is a critical consideration. It is also suitable for voltages below 1.2V and for applications where high efficiency and low dropout is needed. The device offers superior power supply rejection and low quiescent current, which makes it suitable for battery-powered applications.

The L78L15ABD is designed to provide excellent performance and long service life. It is reliable and robust and can be used in a wide range of applications. It is a ideal choice for medium power applications in automotive, industrial and other applications. The device provides low current consumption, high accuracy and low quiescent current.
