Description
The KA78RM33R is a low-dropout voltage regulator suit-
able for various electronic equipment. It provides con-
stant voltage power source with surface-mount type
package (DPAK). The dropout voltage is below 0.6 V in
full-rated current 0.5 A. This regulator has over-current
protection, thermal shut-down and the SOA (Safe oper-
ating Area) protection.
