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 MC78M00/MC78M00A Series positive voltage regulators are identical to the popular MC7800 Series devices, except that they are specified for only half the output current. Like the MC7800 devices, the MC78M00 three-terminal regulators are intended for local, on-card voltage regulation.
Internal current limiting, thermal shutdown circuitry and safe-area compensation for the internal pass transistor combine to make these devices remarkably rugged under most operating conditions. Maximum output current, with adequate heatsinking is 500 mA.

The Onsemi MC78M05CDTRK is a 5 volt positive linear voltage regulator.  It has 0.5 amps, a 4% tolerance and comes in a DPAK package.
