PHOENIX--On Semiconductor Corp. today announced a new CMOS low-noise, low-dropout (LDO) voltage regulator that's designed to improve the performance of circuits in portable product applications. The new regulator also eliminates the need for an external bypass capacitor.
"Performance and size are critical factors in the design of handheld battery-operated products," noted Mitch Polonsky, analog marketing engineer at the Phoenix-based chip company. He said the new NCP500 is designed to provide a cost-effective approach to maximizing battery life in consumer portable products.
Housed in a small SOT23 package, the NCP500 provides a low-dropout voltage of 170 mV typical at 150 mA, said On Semiconductor. It features an enable pin as well as current and temperature limit protection circuits. The voltage regulator operates within a voltage range of 1.8 volts to 6.0 volts.
The NCP500 is offered with seven different output voltages (1.8 to 5.0 volts). All of the versions are available in a 5-lead SOT23 package. Suggested resale price is $0.25 each in quantities of 12,000.
