APPLICATIONS
The typical PNP pass transistor has been replaced by
a PMOS pass element. Because the PMOS pass

current) is directly proportional to the load current.
The quiescent current (3.2μA, typical) is stable over

The TPS714xx is available in a 2mm x 2mm SON-6
package ideal for high power dissipation, or an
SC70-5 package ideal for handheld and ultra-portable
applications.
