The new regulator supports low power designs in applications such as touch screens, keypads, smart phones, portable meters, printers and remote controls.
The company said that the NCP508 can drive currents in excess of 50mA and is housed in a compact SC-88A package with a footprint measuring 2.2 mm x 2.2 mm with an overall height of 1.10mm.
The new device offers ripple rejection of 70dB typical (at 1kHz) that makes it an effective filter for voltage supplies. Noise performance of 40uVrms (at 1.5v) contributes to a clean output voltage, and when disabled a current consumption of less than 1uA helps to further extend battery life in portable equipment, the company said.
In addition, low voltage dropout performance of 140mV at 30mA load provides flexibility in designing auxiliary power rails.
A switch on time of less than 20us allows designers to maximize energy savings by powering down the device when the functionality it supports is not in use, the company further added. The NCP508 can be also be used with low-cost ceramic capacitors.
The NCP508 has a maximum operating voltage of 7v, though it can withstand high voltage transients of up to 13v, thus saving cost by alleviating the need for external protection circuitry. Standard output voltage versions of 1.5v, 1.8v, 2.5v, 2.8v, and 3.3v are offered with other voltage values available in 100mV steps.
Each device incorporates both current limit and over temperature protection circuits. The operating temperature range is -40 degree centigrade to +85 degree centigrade.
Offered in an SC-88A package, the NCP508 is priced at $0.20 per unit for quantities of 3,000 units. A 1.5mm x 1.5mm DFN option is expected to be available later this year.
