LDO Regulator, 3 A, High
Accuracy (1%), Low Noise
(4.3 mVRMS), Low Dropout
(70 mV)
NCP59763
www.onsemi.com
The NCP59763 is a 3 A capable, low noise (4.3 μV
), ultra low
RMS
dropout (70 mV max. at 3 A), fast load transient response linear
regulator (LDO) equipped with an NMOS pass transistor without the
need of external bias voltage. The device output voltage is adjustable
from 0.5 V to 2.0 V through the use of an external resistor divider and
also available in fixed output versions.

The combination of high output current capability, ultra high PSRR
across a wide frequency range and low noise makes this LDO ideal for
powering noise sensitive high speed communication devices. Power
sequencing application flexibility through enable pin, a user
programmable soft−start and a user programmable delayed power good
circuit. Very low dropout voltage (70 mV) and high output voltage
accuracy (1%) enables low input voltage and higher power efficiency.
These set of features makes NCP59763 LDO an ideal solution for
powering analog, digital and mixed signal high current demanding
circuits like analog−to−digital converters (ADCs), digital−to−analog
converters (DACs), high performance serializers and deserializers
(SerDes), application specific integrated circuits (ASICs), field
programmable gate arrays (FPGAs), digital signal processors (DSPs).
