The SPX2920 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 SPX2920
features very low quiescent current (140A Typ.) and very low dropout voltage. This includes a tight initial
tolerance of 1% max 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 of 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, SO-8 (same pin
out as SPX2951), SOT-223, and surface mount 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.
