LDO delivers 500mA peak output in thin package

Keywords:LDO regulators? low dropout regulators? 500mA peak output?

Catalyst Semiconductor Inc. has launched the first device in its new line of LDO regulators. The CAT6219 is one of only a few devices available that provide a 500mA peak output current in a five-lead, 1mm profile thin SOT-23 package.

The CAT6219 offers a lower quiescent current of 55?A combined with a low typical dropout voltage of 300mV at a 500mA load. In addition, an external 10nF bypass capacitor reduces overall output noise making the device suitable for low noise applications.

Although many LDOs incorporating a bypass capacitor pay the penalty of a slow "start up," the CAT6219 is designed with a "quick start" feature, which ensures a fast turn-on time of less than 150?s and further optimizes the CAT6219 for low-power applications, said the company.

The CAT6219 is designed to eliminate battery drain when not in use by entering a "zero" current shutdown mode. The device also offers protection against short-circuit and thermal overload fault conditions.

Pricing is 28 cents each in quantities of 10,000.

Samples are available. Projected lead time for production quantities is six to eight weeks ARO.
