ON Semiconductor Debuts NCP500 LDO Voltage Regulator

April 30, 2001 by Jeff Shepard

ON Semiconductor (Phoenix, AZ) announced the availability of the NCP500 CMOS LDO voltage regulator. Offered in a SOT-23 package, ON Semiconductor claims that the NCP500 LDO regulator features a LDO voltage while achieving low-noise performance without the need of an external bypass capacitor.

Operating within a voltage range of 1.8 to 6.0V, the NCP500 offers a LDO voltage of 170mV typically at 150mA. Other features include an enable pin and current and temperature limit protection circuits. ON Semiconductor offers the device in a

five-lead SOT23 miniature footprint that is optimized for use in cellular handsets, hand-held instruments, MP3 players and other portable consumer products. The company designed the device to work with small, low-cost ceramic capacitors and requires a minimum output capacitor of one microfarad.

“Performance and size are critical factors in the design of hand-held battery-operated products," said Mitch Polonsky, analog marketing engineer at ON Semiconductor. “The NCP500 is the latest in ON Semiconductor's line of CMOS LDO regulators to present designers with an efficient and cost-effective way to maximize battery life in consumer portable products. The introduction of this product demonstrates the company's commitment to address the rapidly growing consumer demand for higher performance portable electronics."

The NCP500 is offered with seven different output voltages: 1.8, 2.5, 2.7, 2.8 3.0, 3.3 and 5.0V. All of the versions are available in a five-lead SOT-23 package. Suggested resale pricing for each NCP500 device is $0.25 per 12,000 units.
