Integrated voltage regulator targets battery-powered apps

The NCP508 low-current voltage regulator can drive currents in excess of 50 mA and is housed in a compact SC-88A package with a footprint measuring 2.2 x 2.2-mm with an overall height of 1.10 mm. It suits low-power, space-efficient, and cost-effective designs in applications such as touchscreens, keypads, smart phones, portable meters, printers, and remote controls. The device offers ripple rejection of 70 dB typ (at 1 kHz), which makes it an effective filter for voltage supplies. It offers noise performance of 40 µVrms (at 1.5 V), and a current consumption of less than 1 µA.

The regulator features a voltage dropout performance of 140-mV at 30-mA load, provides a switch on time of less than 20 µs, and can be used with low-cost ceramic capacitors. It has a maximum operating voltage of 7 V and can withstand high-voltage transients up to 13 V. Standard output-voltage versions of 1.5, 1.8, 2.5, 2.8, and 3.3 V are offered with other voltage values available in 100-mV steps. Each device incorporates both current-limit and overtemperature protection circuits. The operating temperature range is –40° to 85°C. ($0.20 ea/3,000 — available now.)
