STP1117S25

Elektronische Bauelemente STP1117Sxx Series 1.0A Low Dropout Positive Adjustable or Fixed-Mode Regulator RoHS Compliant Product A suffix of “-C” specifies halogen free DESCRIPTION The STP1117Sxx series of positive adjustable and fixed regulators are designed to provide 1A with high efficiency. All internal circuitry is designed to operate down to 1.4V input to output differential. On-chip trimming adjusts the reference voltage to 1%. Current limit the typical value of 1.5A allows to minimizing the stress on both the regulator and the power source circuitry under overload conditions. FEATURES Adjustable or Fixed Output 1.2V,1.8V,2.5V,3.3V Output Current of 1A Low Dropout, 1.2 V typ. at 1A Output Current 0.04% Line Regulation 0.2 % Load Regulation 100% Thermal Limit Burn-In Fast Transient Response APPLICATIONS High Efficiency Linear Regulators Post Regulators for Switching Supplies Adjustable Power Supply MARKING Part Number STP1117SA STP1117S12 STP1117S18 STP1117S25 STP1117S33...
