DESCRIPTION

The SPX2950 and SPX2951 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. TheSPX2950andSPX2951featurelowquiescentcurrent andlowdropoutvoltage(typ.20mV

at100µAand300mVat150mA). Thisincludesatightinitialtoleranceof(0.5%forSPX2950A/SPX2951A),

extremely good load and line regulation (0.05% typ.), and very low output temperature coefficient (20ppm/

°C typ.), making the SPX2950/SPX2951 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

voltage. The logic compatible shutdown feature enables the regulator to be switched ON and OFF. The

SPX2950 is offered in a 3-pin TO-92 package compatible with other 5.0V, 3.3V regulators. The SPX2951

is availiable in an 8-lead SOIC package.
