SPX2954

250mA Low Dropout Voltage Regulators

features

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.

■ 5.0V and 3.3V Versions at

■ Very Low Quiescent Current

■ Low Dropout Voltage: 375mV

at 250mA

■ Extremely Tight Load and Line

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.
