ADM7171ACPZ-3.0-R7 ADI LFCSP-8 进口 低压差稳压器 1A Hi PSRR FT LDO 3.0Vo
产品信息
The ADM7171 is a CMOS, low dropout linear regulator (LDO)
that operates from 2.3 V to 6.5 V and provides up to 1 A of output
current. This high output current LDO is ideal for regulation of
high performance analog and mixed signal circuits operating
from 6 V down to 1.2 V rails. Using an advanced proprietary
architecture, the device provides high power supply rejection and
low noise, and achieves excellent line and load transient response
with just a small 4.7 μF ceramic output capacitor. Load transient
response is typically 1.5 μs for a 1 mA to 500 mA load step.
The ADM7171 is available in 17 fixed output voltage options.
The following voltages are available from stock: 1.3 V, 1.8 V,
2.5 V, 3.0 V, 3.3 V, 4.2 V, and 5.0 V. Additional voltages that
are available by special order are: 1.5 V, 1.85 V, 2.0 V, 2.2 V, 2.7
V, 2.75 V, 2.8 V, 2.85 V, 3.8 V, and 4.6 V. An adjustable version
is also available that allows output voltages that range from 1.2
V to VIN − VDO with an external feedback divider.
Inrush current can be controlled by adjusting the start-up time
via the soft start pin. The typical start-up time with a 1 nF soft
start capacitor is 1.0 ms.
