Higher output current for voltage regulator

Torex Semiconductor has introduced a new high precision positive voltage regulator that combines large output current with a 'significantly' small dropout voltage.

Torex Semiconductor, one of the world's leading manufacturers of power management ICs for battery-powered handheld equipment, has introduced a new high precision positive voltage regulator that combines large output current with a 'significantly' small dropout voltage.

Boasting a 400mA output current at 3.3V, the high precision XC6203E is suitable for a wide range of applications including palmtops, DVDs, CD-ROMs, video cameras and other audio visual equipment.

Dropout voltage is typically 150mV at 100mA and 300mV at 200mA, notably less than competing devices.

Manufactured using the very latest CMOS and laser trimming technologies, the XC6203E combines a driver transistor, a precision voltage reference and an error amplifier within an ultra small SOT-89 package.

Space saving capability is matched by power saving, the new regulator having a current consumption of only 8.0uA and a power dissipation of 500mW.

The XC6203E gives designers a full range of output voltages, spanning 1.8 to 6.0V, selectable in 0.1V steps.

It is a high precision device accurate to +/-2%, making it ideal for use as a CMOS reference voltage source.

Operational temperature range is a wide -40 to 85C while the device's maximum operating voltage is 8V.

The new voltage regulator is pin-compatible with the earlier XC62FP.
