S2123 CMOS Positive Voltage Regulator Elektronische Bauelemente RoHS Compliant Product Description TO-92 D E The S2123 series of positive,linear regulators feature low quiescent S1 A 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 S2123 is stable with an output capacitance of 2.2µF or greater. b1 L SEATING PLANE Features * High Accurate ± 1.5% e1 e * Over-Temperature Shutdown C b * Factory Pre-set Output Voltage * Very Low Dropout Voltage * Low Temperature Coefficient * Short Circuit Current Fold-back * Guaranteed 300mA output * Current Limiting REF.
