 ESR, Stability, and the LDO Regulator
 Jeff Falin PMP Portable Power
 ABSTRACT
 Choosing an output capacitor for LDO regulators with PNP or PMOS pass element can be
 difficult due to specific ESR requirements. This application note explains why higher ESR
 capacitors are necessary, how to choose them, and how to determine whether or not the
 regulator is stable.
