3A低壓差穩(wěn)壓器芯片--G9661-25ADJF11U
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.
