Diodes Incorporated (Nasdaq: DIOD) today announced the AP7353 low dropout regulator, which offers a high power supply rejection ratio (PSRR) in a smal ...

The newly produced GaN diodes have achieved simultaneous high-current operations and low threshold voltage, and thus can handle high currents even with a small chip area.

Keeping the Z PDN small also allows the user to program the output voltage of their regulator to a lower value, saving system power. Z PDN can be decreased by carefully designing the PCB.

A recent Design Idea, “ Three discretes suffice to interface PWM to switching regulators, ” demonstrated one way to use PWM to control the output of a typical switching voltage regulator. There were ...

Krishna said that bringing the voltage regulator closer to the processor’s pins can curtail power losses on the PCB by a factor of 10, raising efficiency at the system level by up to 5%.
