Working Principle

The L78LR05DL-TL-E operates on a linear regulator topology that features an error amplifier, a voltage reference, and a MOSFET pass element, as well as protection circuitry. The device takes the input voltage VIN and reduces it to the regulated output voltage VOUT by dissipating the excess current as heat. The error amplifier monitors the output voltage and compares it to the reference voltage. Any adjustments to the output voltage are made by varying the amount of current through the pass element. The protection circuitry is used to prevent the device from being damaged by excessive current or voltage, over-temperature, or other faults.

In summary, the L78LR05DL-TL-E is an efficient and reliable low dropout linear regulator designed for low power applications. The device utilizes an advanced low power, low dropout (LPoLDO) linear regulator topology and is available in a small, Lead-free, RoHS-compliant, TO-220 package. The device offers excellent performance for small, portable battery-powered devices and is ideal for use in automotive, handheld, consumer, and other similarly power sensitive applications. The device features fast transient response and excellent line and load regulation. It also includes protection features such as reverse current, over-current, and thermal shutdown.
