DESCRIPTION

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 (140µATypical) 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.
