GENERAL DESCRIPTION
TThhee _{AMS2115 is a single IC controller that drives an external N channel MOSFET as a source follower to produce a fast}
transient response, low dropout voltage regulator. The fast transient load performance is obtained by eliminating expensive
tantalum or bulk electrolytic output capacitors in the most demanding modern microprocessor applications. Precision-trimmed
adjustable and fixed output voltage versions accommodate any required microprocessor power supply voltage. By selecting the
N-channel MOSFET RDS(ON) a very low dropout voltage can be achieved. A protection feature includes a high side current
limit amplifier that activates a circuit to limit the FET gate drive. A shutdown pin turns off the gate drive and some internal
circuits to reduce quiescent current. AMS2115 is offered in 8L SOIC and 8L PDIP package.
