The Micrel MIC5156, MIC5157, and MIC5158 Super LDO™
Regulator Controllers offer two features that can be used to
save the pass device. The first feature is a current limit
capability (not implemented in Figure 1). Output current can
be limited at a user-defined value, but the function is not the
classic foldback scheme. While fixed-value current limiting
can reduce shorted-output power dissipation to a manageable
level, the additional dissipation imposed by the short can
still damage the pass device. When considerable voltage is
being dropped by the pass device the short-circuit power
dissipation becomes dramatically high.，大小：429 KB
