Description
The KA78RM33 is a low-dropout voltage regulator suit-
able for various electronic equipments. It provides con-
stant voltage power source with surface mount type
package (D-PAK). The dropout voltage of KA78RM33 is
below 0.6V in full rated current(0.5A). This regulator has
various functions such as an over current protection, a
thermal shut down and the SOA (Safe operating Area)
protection.
