DESCRIPTION
The LT
®
1761 series are micropower, low noise, low
dropout regulators. With an external 0.01μF bypass
capacitor, output noise drops to 20μV
RMS
over a 10Hz to
100kHz bandwidth. Designed for use in battery-powered
systems, the low 20μA quiescent current makes them an
ideal choice. In shutdown, quiescent current drops to less
than 0.1μA. The devices are capable of operating over an
input voltage from 1.8V to 20V, and can supply 100mA of
output current with a dropout voltage of 300mV. Quiescent
current is well controlled, not rising in dropout as it does
with many other regulators.
The LT1761 regulators are stable with output capacitors as
low as 1μF Small ceramic capacitors can be used without
.
the series resistance required by other regulators.
Internal protection circuitry includes reverse battery
protection, current limiting, thermal limiting and reverse
current protection. The device is available in fixed output
voltages of 1.2V, 1.5V, 1.8V, 2V, 2.5V, 2.8V, 3V, 3.3V and
5V, and as an adjustable device with a 1.22V reference
voltage. The LT1761 regulators are available in the 5-lead
TSOT-23 package.

AD9959设置问题需要解答
在开机如何初始化AD9959的主频,即使他倍频。我用万用表测量,如果开机没倍频成功,就后面什么设置都无效,软件复位也无效。 如果倍频成功则无问题。这个失败的概率大概是百分之七左右。看情况 ......
