The SPX2954 and SPX2954A are low power voltage regulators. These devices are an excellent
choice for use in battery-powered applications such as cordless telephones, radio control
systems, and portable computers. The SPX2954 and SPX2954A feature low quiescent current
and low dropout voltage (typ. 20mV at 100μA and 310mV at 250mA). This includes a tight initial
tolerance (0.5% for SPX2954A), extremely good load and line regulation (0.05% typ.), and very
low output temperature coefficient (20 ppm/°C typ.), making the SPX2954/SPX2954A 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-compatible shutdown feature enables the regulator to be
switched ON and OFF. The SPX2954/SPX2954A is offered in 3-pin TO-92, TO-263, SOT-223
and TO-220 packages, and 8 pin SOIC package. SPX2954AT-3-3
