Reduces LDO noise spectral density by a factor
of two
Provides lowest phase noise for powering VCOs;
lowest jitter performance for powering clock devices in microwave
systems
Analog Devices, Inc. (NASDAQ: ADI), a global leader in
high-performance semiconductors for signal processing applications,
announced today the release of ultra-low-noise LDO (low-dropout)
regulators for RF (radio frequency) signal devices. The ADM7150/1
operate from 4.5 V to 16 V, provide up to 800-mA of output current
and support output voltages from 1.5 to 5.0 V. The LDOs achieve an
output-NSD (noise spectral density) of 1.4 nV/rtHz from 10 kHz to 1
MHz, which significantly reduces VCO (voltage-controlled
oscillator) phase noise in point-to-point microwave radios,
satellite communications, defense electronics and other wideband
applications. Additionally, a user adjustable CBYP can
significantly reduce low frequency 1/f noise (8 nV/rtHz at 100 Hz)
for precision analog front-end measurement systems.

In addition to ultra-low noise, the ADM7150/1 achieve line and
load transient responses of 0.01%/V and 0.4%/A respectively with a
10-µF ceramic output capacitor. The new LDOs also feature high PSRR
(power-supply rejection ratio) performance of greater than 90 dB
from 1 kHz to 100 kHz, and greater than 60 dB at 1 MHz. This
effectively filters DC-DC switching regulator ripple, saving space
by minimizing the size of discrete filtering components normally
needed.
