Ultra Small Voltage Regulator with only 0.6µA Quiescent Current.

The XC6504 series of voltage regulators operate at an extremely low supply current of only 0.6µA and come supplied in an ultra-small package with the USPN-4B02, measuring just 0.75 x 0.95mm. When it comes to the choice of capacitor material, the regulator is extremely flexible. On the one hand, low ESR capacitors can be used – or even no capacitors at all. By saving on the capacitors, the PCB space required can be kept extremely small.

With regard to output voltage, the regulator has very high precision. This is maintained even at very small loads, such as only 1µA, which makes the regulator ideal for applications for which low currents are required. The output voltage can be selected in steps of 0.1V increments, from 1.1V to 5.0V, and is set at the production plant by means of laser trimming. A CE pin is likewise provided, and allows for a further reduction in induced current consumption to a value of 0.1µA or less. The load capacity is also discharged in stand-by mode. Current limiting and short-circuit protection are provided for protection purposes. For package variants, a choice can be made between USPN-4B02, SSOT-24 and SOT-25.
