LDO retains regulation longer

High-precision dual-output CMOS LDOs can deliver up to 300mA per output.

ON Semiconductor has introduced the NCP590 family of a very high precision, dual-output CMOS low dropout regulators (LDOs).

Offered in ultrasmall low-profile packages, these devices are ideal for battery powered consumer and microprocessor-controlled portable applications such as cellphones, PDAs, GPS and portable media players.

The NCP590 family of LDOs is capable of delivering up to 300mA per output.

A special combination of process and architecture is employed to offer fast customer response and outstanding flexibility.

Voltages from 0.8 to 5V are available to accommodate the varied needs of customers.

The NCP590 is stable with any type of capacitor and under no-load conditions.

The set point output voltage of the NCP590 is accurate to within +/-0.9% with an operating voltage input up to 5.5V meeting very tight overall error budget requirements of high-performance applications.

With its ultra-low-dropout characteristics (150mV at 300mA output current) and low ground current consumption, the device retains regulation longer and extends battery usage.

These performance features, and the compact 2 x 2 x 0.9mm DFN-8 package they are offered in, make the NCP590 family ideal for all battery operated consumer and microprocessor applications.

Two independent enable pins with sub-1V thresholds allow increased flexibility, supporting the latest ASIC chipset and Power Management Unit platforms.

Protected against short circuit, undervoltage lockout and thermal overload conditions, the NCP590 is a robust solution that helps maintain high system level performance.

During transient events, the NCP590 maintains accurate regulation due to its internally compensated regulator.

When disabled, the internal active discharge circuitry accelerates desired output response.

The NCP590 is offered in a DFN-8 package and priced at US $0.37 per unit in 10,000-unit quantities.
