High Current, High Accuracy LDO from Diodes Incorporated Addresses Noise-Sensitive Power Conversion Applications

Business Wire
Diodes Incorporated (Diodes) (Nasdaq: DIOD) has released a
3A-rated low-dropout (LDO) voltage regulator supporting 4.4µVRMS
operation (at 0.8V output). Delivering a clean supply, the AP7179D
is highly optimized for powering noise-sensitive components - such
as the high-performance SerDes, RF components, and data converters
needed for high-speed communications, test and measurement,
medical, and video applications. Remote radio units (RRUs), outdoor
backhaul units, mMIMO active antenna systems, ultrasound scanners,
radar systems, and lab/field instrumentation are among the types of
hardware into which it can be incorporated.
The AP7179D has a ±1% output accuracy across line, load, and
temperature. This device’s 180mV (maximum) dropout voltage at a 3A
load current supports a wide voltage conversion range. Its
low-noise reference and error amplifier enables a minimal noise
floor. In addition, its 40dB power supply rejection ratio (PSRR) at
500kHz substantially lowers the coupling of input supply noise to
the output.
There are two output voltage selection modes for this LDO:
pin-programmable between 0.8V and 3.95V, or adjustable using an
external resistor divider from 0.8V to 5.5V. The resulting
flexibility significantly reduces the number of accompanying
components needed.
The device’s low output noise mitigates both
power-supply-generated phase noise and clock jitter. Because of
this, alongside its high-current capabilities, this device is
compatible with high-performance processors, such as FPGAs, ASICs,
and DSPs.
The AP7179D is housed in a compact 20-pin W-QFN3535 (Type A1)
package, and it is available at $0.70 in 1,000 unit quantities.
