LDOs slim for PCMCIA applications

Edited by the Electronicstalk editorial team Aug 6, 2003

Torex Semiconductor has developed an even slimmer version of its chip scale package for PCMCIA applications.

In battery-powered handheld and portable equipment size really does matter.

Nowhere is this more so than in PCMCIA applications where package height is crucial.

In order to ease designers' space constraints, Torex Semiconductor has developed an even slimmer version of its chip scale package, the new USP-6C, and introduced two of its world-leading families of low-dropout voltage regulators packaged in it.

The plastic-moulded ultraslim USP-6C measures only 1.8 x 2.0 x 0.6mm, which is 25% lower than the company's first chip scale package, the 0.8mm-high USP-6B.

According to marketing manager Andy Scott: "A 0.2mm drop in height may not seem much, but in PC card applications like PCMCIA it makes a whole world of difference.

Being able to offer our leading-edge voltage regulators in the new package will give designs in this area a significant boost".

The first two Torex products to be made available in the new USP-6C package are the high-speed, low noise XC6209 series and the popular XC6201 series LDO voltage regulators.

The XC6209's low power consumption (25mA typical) and very high speed of operation makes it ideal for Bluetooth applications.

Its output noise rating of 30mV RMS means it can be used in a wide range of low-noise RF applications such as GSM and DECT phones, as well as a whole host of other battery-powered applications from PDAs to portable games.

Output voltage range is 0.9 to 6.0V, selectable in 50mV increments.

The XC6209 has a ripple rejection of 60dB (10kHz).

Extremely cost competitive, the XC6201 is specifically aimed at the lower cost end of the applications spectrum and is ideal for mobile and cordless phones, cameras and video recorders, handheld games and portable AV equipment.

Available in output voltages ranging from 2.0 to 6.0V selectable in 0.1V steps, the XC6201 provides designers with large output currents up to 150mA together with a significantly small dropout voltage down to 200mV at 80mA.

At only 2mA, the voltage regulator's power consumption is sufficiently low enough to remove the need for a power shutdown function in the majority of applications.
