Advanced Monolithic Systems AMS2115
The 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. By selecting the Nchannel MOSFET Rds(on) a very low dropout voltage can be achieve.| Part No. | AMS2115 |

GENERAL DESCRIPTION
Precision-trimmed adjustable and fixed output voltage version accommodates any required microprocessor application. 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 package.FEATURES
