LDO regulator with 2% accuracy

Posted: 09 Jun 2005 ?? ?Print Version ?Bookmark and Share


The new dual output low dropout linear regulator from ON Semiconductor provides a 2 percent accuracy over its operating temperature range. The device features a fixed output voltage of 3.3V (contact factory for other fixed output voltage options) and an adjustable output that ranges from 1.25V to 5V.

Rated for operation between the -25C to 85C temperature range, the CP5504 regulator has a ripple rejection of 75dB and a dropout of 250mV at 250mA that suits post-regulation and power sensitive battery-operated applications. The new product provides low noise operation without a bypass capacitor for the fixed output. In addition, it features a quiescent current of 370?A, and thermal protection and current limit.

Priced at 43 cents, the NCP5504 is available in a 5 pin DPAK Pb-free package and employs an architecture that offers low noise without a bypass capacitor for the fixed output.
