Sipex Introduces a Family of Four High Output Current LDOs



(Milpitas, CA - June 27, 2003) - Sipex Corporation (NASDAQ:SIPX) today introduced a new family of Low Dropout (LDO) Linear Regulators to its power management product line. The SPX2950x family provides output current of up to 5A, a very low dropout of 400mV (typ) and fast transient response. These features make the family of LDOs ideal for a variety of PC applications including VGA cards, sound cards and power supplies as well as equipment for telecommunications and industrial process control.

Offered in the industry standard TO-220 or the TO-263 packages, the SPX2950x family is available with fixed output voltages of 1.8V, 2.5V, 3.3V, and 5V, as well as adjustable output voltages of 1.24V to 15V. The devices are highly stable with ceramic capacitors, provide 1% output accuracy, and offer load regulation of 1% with line regulation of 0.06%.

The devices operate from voltages as high as 16V and are fully fault protected against over current, reverse battery, and positive and negative voltage transients. The family of products also offers optional enhancements such as Enable and Error Flag features.

SPX2950x Typical Features
Output Current: 5A
Dropout Voltage: 400mV at Full Load
Optimized for Fast Transient Response
Adjustable Output from 1.24V to 15V
Fixed Output: 1.8V, 2.5V, 3.3V, 5V
