MaxLinear SPX3940
The SPX3940 is a 1A, accurate voltage regulator with a low drop out voltage of 280mV (typical) at 1A. 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 overcurrent, reverse battery, and positive and negative voltage transients.- Min Voltage : 4.3V
- Max Voltage : 16V
- Max Operating Temp : 125°C
- Min Operating Temp : -40°C
