SECOS SJ2138

SJ2138
1.5A CMOS
Elektronische Bauelemente
Low Dropout Voltage Regulator
RoHS Compliant Product
TO-252
Description
The SJ2138 series of positive,linear regulators feature low quiescent
current (45µA 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 SJ 2138 is stable with an
output capacitance of 4.7µF or greater.
Features
* Low Temperature Coefficient
* Over-Temperature Shutdown
* Very Low Dropout Voltage
* High Accurate ± 1.5%
* Short Circuit Current Fold-back
* Guaranteed 1.5A output
* Current Limiting
