2a ultra low dropout linear regulator
applications
the fp6145b is a 2a 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, control voltage for the circuitry and main supply voltage for power conversion, to reduce power dissipation and provide extremely low dropout. the fp6145b integrates many functions. power-on-reset (por) circuit monitors both supply voltages to prevent wrong operations. thermal shutdown and current limit functions protect the device against thermal and current over-loads. pok indicates the output status with time delay which is set internally. it can control other converter for power sequence. the fp6145b can be enabled by other power system. pulling and holding the en pin below 0.4v shuts off the output.
the fp6145b is available in sop-8 (ep) package which features small size as an exposed pad to reduce the junction-to-case resistance.
