If the adjacent plane is close to the split plane and there is a lot of overlap area on each side of the split, the ground impedance will be quite low, and most of the ground current
will follow that path.
The NCP5915x, NCP5930x, and NCP5830x series are high precision, very low dropout, low ground current
voltage regulators that are capable of providing large load currents with a typical dropout voltage lower than 300mV.
Fabricated in CMOS technology, the MIC5319 sets a new industry standard for high-current LDO performance with a PSRR of more than 70dB at 1kHz and a ground current
of less than 90uA typical across the load range, giving the industry's best PSRR-to-current ratio.
Her current research is concerned with the biological effects of electromagnetic pollution including radio frequency radiation, electromagnetic fields, dirty electricity and ground current
The MIC5253's low dropout, high PSRR, and low ground current
, coupled with low noise and fast turn-on time, make it an ideal solution for demanding consumer electronic applications," says Steve Knoth, LDO product marketing manager, Micrel.
The IC's low dropout, high PSRR, and low ground current
, coupled with low noise and fast turn-on time, make it an ideal solution for today's most demanding portable applications.
With its ultra low dropout characteristics (150mV@Iout=300mA) and low ground current
consumption, the devices retains regulation longer and extends battery usage.
The AAT3223 allows designers to use an LDO with an extremely low ground current
while eliminating the external microprocessor reset circuit normally required to support PowerOK.
It features PSRR of over 85dB at 1kHz and ground current
of less than 90uA at full load of 150mA, offering the best ratio of PSRR/Ignd in the industry.
Providing low ground current
independent of output load, these devices reduce power losses.
An initial voltage reference with 2% tolerance over load/line and temperature range (0 to 120 degrees Celsius) is included, with an ultra-low ground current
of 650 micro amps over the full load range.
The Si91871 and Si91872 feature a low ground current
- ideal for low-voltage, battery-operated power systems - and low dropout voltage of 250 mV at 300 mA, prolonging battery life in portable electronics.
