PRODUCT DESCRIPTION
The SPX2941 is a low power positive Adjustable Voltage Regulator. The SPX2941 offers 1A output current with dropout voltage of
only 0.5 Volts with a maximum of 1V dropout over temperature. The quiescent current is 30mA at differential output of 5V and
output current of 1A. The higher quiescent current exists only when the device is in dropout mode
(V
IN
– V
OUT
< 3V).
Other key features of this device include higher output current, positive transient protection up to 60V (Load dump), and ability to
survive an unregulated input voltage transient of -20V below ground (reverse battery). The regulator will automatically shut down to
protect both the internal circuits and the load. This device also features short circuit and thermal overload protection.
The SPX2941 is offered in a 5-pin TO-263 and TO-220 package compatible with other adjustable regulators. This device offers an
adjustable output voltage from 5V to 20V. SPX2941 is a direct replacement to LM2941.
