ON Semiconductor has introduced its NCP590 family of high precision, dual-output CMOS low dropout (LDO) regulators. Housed in ultrasmall, low profile packages, these devices are well suited for battery-powered portable applications.

This family of LDOs is capable of delivering up to 300 mA per output at voltages from 0.8 V to 5 V. The NCP590 is stable with any type of capacitor and under no-load conditions. The set point output voltage is accurate to within ±0.9% with an operating voltage input up to 5.5 V, thereby meeting very tight overall error budget requirements for high-performance applications.With its ultra low dropout characteristics — 150 mV at an Iout of 300 mA — and low ground current consumption, the devices retain regulation over a wide range of load conditions. The NCP590 family of LDOs are housed in 2 mm x 2 mm x 0.9 mm DFN-8 package.

Two independent enable pins with sub 1 V thresholds support the latest ASIC chipset and power management unit platforms. The family is also protected against short circuit, undervoltage lockout and thermal overload conditions. During transient events, the NCP590 is able to maintain accurate regulation due to its internally compensated regulator.

The NCP590 in a DFN-8 package is priced at $0.37 each in 10,000 piece quantities.
