The SPX2920 is a low power voltage regulator. This device is an excellent choice for use in batterypowered applications such as cordless telephones, radio control systems, and portable computers. The SPX2920 features very low quiescent current (140A Typical) and very low dropout voltage. This includes a tight initial tolerance of 1% maximum and very low output temperature coefficient, making the SPX2920 useful as a low-power 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 from batteries. Another feature is the logic-compatible shutdown input which enables the regulator to be switched on and off. The SPX2920 is offered in 3-pin TO-220 package, surface mount SO-8 (same pin out as SPX2951), SOT-223, and 3-pin TO-263 packages. The regulator output voltage (of the SO-8) may be pin-strapped for a 3.3V and 5.0V or programmed from 1.24V to 20V with an external pair of resistors. TO-263-3 (T)
