SPX2954  
250mA Low Dropout Voltage Regulator  
Description  
FEATURES  
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.

5.0V and 3.3V versions at 250mA output  
Accurate 0.5% for SPX2954A  
Very low quiescent current  
Low dropout: 310mV at 250mA  
Extremely tight load and line regulation  
Very low temperature coefficient  
Current and thermal limiting  
Need only 1µF for stability  
Direct replacement for LP2954  
Error flag warns of output dropout  
Logic-controlled electronic shutdown  
Programmable output from 1.24V to 30V  
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 a 3-pin SOT-223  
package and an 8-pin SOIC package.
