Product Preview
1 A Low Noise, RF LDO
Voltage Regulator
The NCV59800 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 NCV59800 is available in the 3 mm x 3 mm

APPLICATIONS INFORMATION
General Information
capacitance values 4.7 mF up to 100 mF. This device is
evaluated using a 4.7 mF/10 V, 10% tolerance, X5R type
Ceramic Capacitors of 0805 size.
X5R− and X7R−type capacitors are highly recommended
because they have minimal variation in value and ESR over
temperature.
The NCV59800 regulator is equipped with Noise
Reduction pin (NR) for noise sensitive applications. A noise
reduction capacitor (CNR) at the NR pin bypasses noise
generated by the bandgap reference. This family of
regulators offers sub−bandgap output voltages, current
limit, and thermal protection, and is fully specified from
–40°C to +125°C. assuming resistors with zero error. For the
actual design, pay attention to any resistor error factors.

The CNR serves not only for noise reduction. During
Start−Up the CNR capacitor works like the Soft Start timing

Power Dissipation
Capacitors Selection
The maximum power dissipation supported by the device
is dependent upon board design and layout. Mounting pad
configuration on the PCB, the board material, and the
ambient temperature affect the rate of junction temperature
rise for the part. For reliable operation junction temperature
should be limited to +125°C.
Although an input capacitor is not required for stability, it
is good analog design practice to connect a 0.1 mF to 1.0 mF
low equivalent series resistance (ESR) capacitor across the
input supply near the regulator. The NCV59800 is designed
to be stable with standard ceramic output capacitors of
