? GENERAL DESCRIPTION

The AX6615 is a 3A ultra low dropout linear regulator. This product is specifically designed to provide well supply voltage for front-side-bus termination on motherboards and NB applications. The IC needs two supply voltages, a control voltage for the circuitry and a main supply voltage for power conversion, to reduce power dissipation and provide extremely low dropout. The AX6615 integrates many functions. A Power-On-Reset (POR) circuit monitors both supply voltages to prevent wrong operations. A thermal shutdown and current limit functions protect the device against thermal and current over-loads. The AX6615 can be enabled by other power system. Pulling and holding the EN pin below 0.3V shuts off the output.

The AX6615 is available in SOP-8L-EP and TDFN-10L packages which features small size as an Exposed Pad to reduce the junction-to-case resistance, being applicable in 2~3W applications.
