NCP59800
1 A Low Noise, RF LDO
Voltage Regulator
The NCP59800 is a family of 1 A low−dropout linear regulators
(LDOs) offering high power−supply ripple rejection (PSRR) and
ultra−low output noise. This series of LDOs uses an advanced
BiCMOS process to achieve very good electrical performance. It is an
ideal choice for noise sensitive Analog RF Front−Ends used in
Telecom Equipment. The NCP59800 is available in the 3 mm x 3 mm
DFN8 package.

5 EN Driving the enable pin (EN) high turns on the regulator.
Driving this pin low puts the regulator into shutdown mode.
6 NR Connect an external capacitor between this pin and ground to reduce the output noise to very
low levels. The capacitor slows down the V

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.

V
OUT
