G9661-25ADJRE1U 台湾致新3A低压差调节器

　　General Description

　　The G9661 is a high performance positive voltage regulator designed for use in applications requiring very low Input voltage and very low dropout voltage at up to 2 amps. It operates with a VIN as low as 1.1V and VPP voltage 5V with output voltage programmable as low as 0.8V. The G9661 features ultra low dropout, ideal for applications where VOUT is very close to VIN. Additionally, the G9661 has an enable pin to further reduce power dissipation while shutdown. The G9661 provides excellent regulation over variations in line, load and temperature. The G9661 provides a power OK signal to indicate if the voltage level of VO reaches 92% of its rating value.

　　The G9661is available with 2.5V internally preset outputs that are also adjustable using external resistors.
