Linear regulators are Step-Down regulators only. There are 2 types of regulators, Shunt and series-pass regulators.

For IC linear voltage regulators, the regulator type determines the configuration of the pass device as well as the dropout voltage. Standard voltage regulators use an NPN Darlington configuration and have a dropout voltage between 1.5V and 2.2 V. Low dropout (LDO) regulators differ from standard regulators in that the pass device consists of a single PNP transistor

Linear regulators provide significant advantages over switching regulators in simplicity, cost, and output noise.

The only difference between a 'normal' linear regulator and a LDO one is that, the LDO type can have a lower constant voltage-drop across the series-pass element.

The L78xx series of three-terminal positive regulators is available in TO-220, TO-220FP, TO-3, D2PAK and DPAK packages and several fixed output voltages, making it useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution problems associated with single point regulation. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1 A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents.

The ST Micro L7805ACV is a 5 volt positive linear regulator.  It has 1 amperage, a 4% tolerance, commercial temperature, and comes in a TO-220 package.
