TS39150CM12

TS39150 1.5A Ultra Low Dropout Fixed Positive Voltage Regulator TO-263 Pin assignment: 1. Input 2. Ground 3. Output Low Dropout Voltage 0.4V (typ.) General Description The TS39150 series are using process with a PNP pass element for high current, high accuracy and low dropout voltage regulators. These regulator s feature 400mV(typ) dropout voltages and very low ground current, these devices also find applications in lower current and low dropout critical systems, where their tiny dropout voltage and ground current values are important attributes. The TS39150 are fully protected against over current faults, reversed input polarity, reversed lead insertion, over temperature operation, and positive and negative transient voltage spikes. This series is offered in 3-pin TO-263, TO-220 package. Features Dropout voltage typically 0.4V @Io=1.5A Output current up to 1.5A Low ground current Output voltage trimmed before assembly Extremely fast transient response +20V Transient peak voltage -20V Reverse peak voltage Internal current limit Thermal shutdown protection Block Diagram Applications Battery power equipment Automotive electronics High efficiency “Green” computer system High efficiency linear power supplies High efficiency post regulator for switching supply Ordering Information Part No. TS39150CZxx TS39150CMxx Operation Temp.
