SE2138
1.5A CMOS
Low Dropout Voltage Regulator
Description
RoHS Compliant Product
The SE2138 positive,linear regulators feature low quiescent
current (45µA typ.) with low dropout voltage, making them ideal
for battery applications.These rugged devices have bothThermal
Shutdown and Current Fold-back to prevent device failure under
the "Worst" of operating conditions.The SE2138 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
