■GENERAL DESCRIPTION

The XD6702 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 IC is put in the standby state by inputting L level into the CE pin, and the supply current is re

duced to 0.1μA.
