3 / 12 page CAT3200/3200-5 3 Doc No. MD-5002, Rev. L © Catalyst Semiconductor, Inc. Characteristics subject to change without notice Note 1: ROL = (2VIN - VOUT)/IOUT Note 2: In the event of a controlled shutdown, the output will be isolated from the input, but will remain connected to the internal resistor feedback network. This will cause a small level of reverse current to flow back into the device to ground. ELECTRICAL SPECIFICATIONS Recommended operating conditions unless otherwise specified. CIN, COUT, CFLY are 1 µF ceramic capacitors and VIN is set to 3.6V. ABSOLUTE MAXIMUM RATINGS VIN, VOUT, SHDN, CNEG, CPOS Voltage .. -0.6V to 6.0V VOUT Short Circuit Duration .........................
