SM2114 CMOS Positive Voltage Regulator Elektronische Bauelemente RoHS Compliant Product SOT-89 Description The SM2114 series of positive,linear regulators feature low quiescent current (30µA 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 SM2114 is stable with an output capacitance of 2.2µF or greater. Features * High Accurate ±2% * Over-Temperature Shutdown * Factory Pre-set Output Voltage * Very Low Dropout Voltage * Low Temperature Coefficient * Short Circuit Current Fold-back * Guaranteed 350mA output REF.
