One clear advantage of this structure is that only half the ground current
needs to cross the split plane, thus cutting the effect of the split in half.
24V to 13V or internally fixed, a ground current
To improve the relatively poor dynamic behavior of the constant bias (constant IGND) LDOs in newer devices, the ground current
changes proportionally to the output current.
Continuity of the ground currents
is maintained by an electromagnetic coupling of the groundplanes.
Providing low ground current
independent of output load, these devices reduce power losses.
Under a 150-mA load condition, the SiP21101 and SiP21102 feature an extraordinarily low dropout of 130-mV and a ground current
of 110 microamps, helping to prolong battery life in low-voltage portable electronic systems.
Benefiting from its CMOS wafer production process, the LX8820's superior performance increases efficiency by minimizing operating ground current
, typically to less than 200 micro-amps.
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.
4%-owned subsidiary of Vishay Intertechnology (NYSE:VSH), today announced the launch of the Si9185, a 500-mA CMOS low-dropout (LDO) regulator that features very low dropout and ground current
in an exceptionally compact, thermally enhanced MLP33 PowerPAK package.
The LX8816's design is optimized for system efficiency, consuming minimal ground current
and directing quiescent current to the load.
This protects equipment against damage from electrical surges and differences in ground current
Each of the new voltage regulators features an ultra-low ground current
of only 110 microamps at 150 mA -- ideal for low-voltage battery-operated power systems -- and an extraordinarily low dropout voltage of 130 mV, prolonging battery life in portable electronics.
Also available is the ILC7011, an 80mA ultra low noise LDO with ground current
less than 90uA at full load, in a 5-lead SC-70 footprint that is half the size of the industry standard SOT23.
Additionally, the powertrain requires specialized filters to reduce electromagnetic noise, voltage spikes, and ground currents
in order to further extend the life of the electric motor and to reduce interference with communication systems within the vehicle.
