PRODUCT DESCRIPTION
The SPX3940/41/42 is a low power voltage regulator. This device is an excellent choice for battery-powered applications such as cordless telephones, radio control systems and portable computers. The SPX3940/41/42 features very low quiescent current (100µA Typ.) and very low dropout voltage. This includes a tight initial tolerance of 1% max and 2% max., and very low output temperature coefficient, making the SPX3940/41/42 useful as a low-power voltage reference.
