General Description
The TS9230 is a 3A ultra low dropout voltage 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 TS9230 integrates multi-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. A POK indicates the output status with time delay
which is set internally. It can control other converter for power sequence. The TS9230 can be enabled by other
power system. Pulling and holding the EN pin below 0.4V shuts off the output.
