AMS2115

FAST TRANSIENT RESPONSE LOW DROPOUT REGULATOR

FEATURES

APPLICATIONS

• Fast Transient Response

• Microprocessor Supplies

• Video Card Supplies

• Low Voltage Logic Supplies

• GTL Termination

• Dropout Voltage Defined by FET Used

• Very Tight Load Regulation

• High Side Sense Current Limit

GENERAL DESCRIPTION

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. 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.
