Freescale Semiconductor

Table 17 provides the linear regulator operating specifications for the SCF5250 processor.

Table 18 provides the DC electrical specifications.

Table 17. Linear Regulator1 Operating Specification

1 A pmos regulator is employed as a current source in this Linear regulator, so a 10µF capacitor (ESR 0 ... 5 Ohm) is needed on the output pin

(LINOUT) to integrate the current. Typically this will require the use of a Tantalum type capacitor.
