XC6702 Series ETR03074-005 36V input, 300mA low supply current, high speed voltage regulators GENERAL DESCRIPTION The XC6702 series are CMOS high-speed voltage regulator ICs with a 36 V input and low supply current. Internal circuitry includes a reference voltage supply, error amplifier, driver transistor, over-current protection circuit, overheat protection circuit, soft start circuit, and phase compensation circuit. The output voltage is fixed internally by laser trimming, and product selections from 1.8V to 18.0V are available. The over-current protection circuit and overheat protection circuit are built-in, and when the output current reaches the current limit or the junction temperature reaches the temperature limit, the corresponding circuit activates. The soft start circuit limits the rush current that flows from V to V when the IC starts, enabling a stable startup sequence. IN OUT The IC is put in the standby state by inputting L level into the CE pin, and the supply current is reduced to 0.1A. A low-ESR capacitor such as a ceramic capacitor can also be used for C .
