FEATURES

DESCRIPTION

The CS52015 series of positive adjustable and fixed regulators are designed to provide 1.5A with higher efficiency than currently available devices. All internal circuitry is designed to operate down to 700 mV input to output differential and the dropout voltage is fully specified as a function of load current. Dropout voltage of the device is 100 mV at light loads and rising to 700 mV at maximum output current. A second low current input is required to achieve this dropout.The CS52015 can also be used as a single supply device (3 pin version). 3.3v 2.5v,1.5A 124 124 0.1F 10F 10V 150F Typical application data 2.5V,1.5A regulator Load VCONTROL VPOWER V =V (1+R2/R1)+I R2OUT REF ADJ VSENSE VOUT CS52015 Adjust FRONT VIEW SOT-223 IN OUT ADJ/GND TAB IS VOUT FRONT VIEW T0-263 IN OUT ADJ/GND TAB IS VOUT FRONT VIEW
