ISP278R12

ISP278R12 Low Dropout Voltage Regulators DESCRIPTION The ISP278R12 is a low-dropout voltage regulator suitable for various electronic equipments. Dropout voltage of ISP278R12 Series is below 0.5V in full rated current (1.6A). Cause the series have been designed for high current loads, so they are also used in lower current, extremely low dropout-critical systems (in which their tiny dropout voltage and ground current values are important attributes).
