3A低压差稳压器芯片--G9661-25ADJF11U  可替换G964-25ADJP11U.

Peak 3A, Low Dropout Regulator with Enable

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 G9661 is available in the power TSOT-23-6,

SOP-8(FD), MSOP-10(FD) and TDFN3X3-10 package.

It is available with 2.5V internally preset outputs that

are also adjustable using external resistors.
