Low Power Consumption CMOS Regulators

In recent years, along with rising demand for low power consumption sets, demand has also been rising for low power

consumption regulators that supply power.

NEC Electronics has adopted CMOS process technology to develop low power consumption regulators.

*Under development (as of December 2006)

Features

• High current power supply ICs in line with growing capacity requirements of LSIs: μPD121A10 (2.0A), μPD121WxxA

(1.5A), μPD12115 (1.0A)

• Equipped with on-chip on/off function and having a 1 μA circuit current when off: μPD121A10, μPD121WxxA, μPD12115

• Dual power supply input system contributing to low power consumption: μPD121A10

Applications

• Core power supply for 90 nm process ASICs (e.g., NEC Electronics CB-90): μPD121A10

• General-purpose power supplies for low voltage LSIs: μPD121WxxA, μPD12115

• Suited for use with digital home appliances, such as printers and DVD recorders.

Details of dual power supply input system (μPD121A10)

Voltage difference between the INPUT and OUTPUT pins can be minimized by

dividing the power supply into two parts.

Divides the power

supply into an input

(VIN) for obtaining

output (VOUT), and

into a bias voltage

(VDD) for IC operation.
