description
The SPX2954 is a low power voltage regulator. This device is an
excellent choice for use in battery-powered applications such as cord-
less telephones, radio control systems, and portable computers. The
SPX2954 has a low quiescent current and low dropout voltage (typ.
375 mV at 250mA). This includes a tight initial tolerance of 0.5%
(typ.), extremely good load and line regulation (0.05% typ.), and very
low output temperature coefficient, making it useful as a low-power
voltage reference.
The error flag output feature is used as a power-on reset for warning
of a low output voltage, due to a falling input voltage. The logic-com-
patible shutdown feature enables the regulator to be switched ON and
OFF. The SPX2954 is offered in a variety of industry standard pack-
ages and is compatible with other 3.3V AND 5.0V regulators.
