DESCRIPTION
The SPX2945 is a low power voltage regulator. This device is an excellent choice for use in battery-powered applications such as cordless telephones, radio control systems, and portable computers. The SPX2945 features very low quiescent current (100µA Typ.) and very low dropout voltage. This includes a tight initial tolerance of 1% max and very low output temperature coefficient, making the SPX2945 useful as a lowpower voltage reference.

FEATURES
■ Output 3.3V, 5.0V at 400mA Output
■ Very Low Quiescent Current, 100µA
■ Low Dropout Voltage, 420mV at 400mA
■ Extremely Tight Load and Line Regulation
■ Very Low Temperature Coefficient
■ Current & Thermal Limiting
■ Error Flag Warns Of Output Dropout
■ Logic-Controlled Electronic Shutdown
■ Output Programmable From 1.24V to 20V (for SO-8)
