It operates with VPP voltage 5V and output voltage programmable as low as 0.8V. The G973 features ultra low dropout, ideal for applications where VOUT is very close to VIN. Additionally, the G973 has an enable pin to further reduce power dissipation while shutdown. The G973 provides excellent regulation over variations in line, load and temperature. The G973 provides a power OK signal to indicate if the voltage level of VO reaches 92% of its rating value. The G973 is available in the power SOP-8 (FD) package. It is availab...
