NCP163
250 mA, Ultra-Low Noise
and High PSRR LDO
Regulator for RF and
Analog Circuits
The NCP163 is a next generation of high PSRR, ultra−low noise
LDO capable of supplying 250 mA output current. Designed to meet
the requirements of RF and sensitive analog circuits, the NCP163
device provides ultra−low noise, high PSRR and low quiescent
current. The device also offer excelent load/line transients. The
NCP163 is designed to work with a 1
mF
input and a 1
mF
output
ceramic capacitor. It is available in two thickness ultra−small 0.35P,
WLCSP Packages, XDFN4 0.65P and industry standard SOT23−5L.

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
4. Performance guaranteed over the indicated operating temperature range by design and/or characterization. Production tested at T
A
= 25°C.
Low duty cycle pulse techniques are used during the testing to maintain the junction temperature as close to ambient as possible.
5. Dropout voltage is characterized when V
