AX6615

3A Ultra Low Dropout Linear Regulator



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.
