It operates with VPP voltage 5V and output voltage programmable as low as 0.8V. The G975 features ultra low dropout, ideal for applications where VOUT is very close to VIN. Additionally, the G975 has an enable pin to further reduce power dissipation while shutdown. The G975 provides excellent regula- tion over variations in line, load and temperature. The G975 provides a power OK signal to indicate if the voltage level of VO reaches 92% of its rating value. The G975 is available in the power SOP-8 (FD) pack- age. It is available with 1.05V, 1.2V, 1.8V and 2.5V internally preset outputs that are also adjustable using external resistors. Ordering Information ORDER NUMBER MARKING TEMP.
