RoHS Compliant Product
SQ2143
CMOS Positive
Voltage Regulator
Description
The SQ2143 series of positive,linear regulators feature low quiescent
current (35µA typ.) with low dropout voltage, making them ideal
for battery applications. These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under the "Worst" of
operating conditions.
The SQ2143 is stable with an output capacitance of 2.2µF or greater.
Features
* High Accurate ± 1.5%
* Over-Temperature Shutdown
* Adjustable Output Voltage
* Very Low Dropout Voltage
* Low Temperature Coefficient
* Short Circuit Current Fold-back
* Guaranteed 300mA output
* Current Limiting
