High PSRR, 150mA CMOS LDO

General Description
The AME8833 family of positive, linear regulators fea-
ture low quiescent current (50µA typ.) low dropout volt-
age and excellent PSRR, thus making them ideal for Tele-
communications and other battery applications. The ul-
tra-small SC-70 package is attractive for "Pocket" and
"Hand Held" applications.
AME8834’s output voltage can be adjusted with an
external resister divider.
These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under the
"Worst" of operating conditions.
As an additional feature, the AME8833/8834 is stable
with an output capacitance of just extended 0.22µF or
greater.

MSP430-G2购买时需要国际上的卡来购买,有什么办法
RT,这块板子感觉还是蛮好的MSP430-G2购买时需要国际上的卡来购买,有什么办法一般的visa卡就行不过现在别买TI那边没货我的还在等,貌似一个月了visa卡也没有,一般的银联卡还不行,中国区没有卖?回复沙发hxm0070的帖子中国有代理商卖,但是貌似很贵在TI的e-store上买的话是从美国发货visa卡的问题可以请求同学或同事帮助现在一般的信用卡都支持visa吧同学的话招行的young卡就行回复板凳lrz123的帖子...
