DESCRIPTION

The SPX2945 is a low power voltage regulator. This includes a tight initial tolerance of 1% max and very low output temperature coefficient, making the SPX2945 useful as a lowpower voltage reference. The error flag output feature is used as power-on reset for warning of a low output voltage, due to a falling voltage input of batteries. Another feature is the logic-compatible shutdown input which enables the regulator to be switched on and off.
