Voltage regulator chip roundup

Sunday, March 27th, 2011

McZ and rsdio tipped us to a bunch of new and wonderful voltage regulator chips. Tiny regulators, high current regulators, and high voltage regulators. TPS84620: 4.5V to 14.5V input, 6A switching regulator needs only three external parts MAX15040: 2.4V to 3.6V input, 4A switching regulator is the smallest yet MAX15050/MAX15051:...
