NCV8130
300 mA, Very Low Dropout
Bias Rail CMOS Voltage
Regulator
The NCV8130 is a 300 mA VLDO equipped with NMOS pass
transistor and a separate bias supply voltage (V
BIAS
). The device
provides very stable, accurate output voltage with low noise suitable
for space constrained, noise sensitive applications. In order to
optimize performance for battery operated portable applications, the
NCV8130 features low I
Q
consumption. The XDFN6 1.2 mm x
1.2 mm package is optimized for use in space constrained
applications.

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. Effective capacitance, including the effect of DC bias, tolerance and temperature. See the Application Information section for more
information.
5. 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.
6. Dropout voltage is characterized when V
OUT
falls 3% below V
OUT(NOM)
.
7. For output voltages below 0.9 V, V
BIAS
dropout voltage does not apply due to a minimum Bias operating voltage of 2.4 V.
