SPX2940

1A Low Dropout Voltage Regulator

August 2009

Rev. 2.0.0

GENERAL DESCRIPTION

APPLICATIONS

The SPX2940 is a 1A, accurate voltage

regulators with a low drop out voltage of

280mV (typical) at 1A.

• Power Supplies

• LCD Monitors

• Portable Instrumentation

• Medical and Industrial Equipments

These regulators are specifically designed for

low voltage applications that require a low

dropout voltage and a fast transient response.

They are fully fault protected against over-

current, reverse battery, and positive and

negative voltage transients.

FEATURES

• Guaranteed 1.5A Peak Current

• Low Quiescent Current

• Low Dropout Voltage of 280mV at 1A

The SPX2940 is offered in 3-pin TO-220 & TO-

263 packages. For a 3A version, refer to the

SPX29300 data sheet.

• Extremely Tight Load and Line

Regulation

• Extremely Fast Transient Response

• Reverse-battery Protection

• Internal Thermal Protection

• Internal Short Circuit Current Limit

• Replacement for LM2940, MIC2940A,

AS2940

• Standard TO-220 and TO-263 packages
