XC6701 Series ETR0334-012b 28V Operation High Speed Voltage Regulators with Stand-by Function GENERAL DESCRIPTION The XC6701 series are positive voltage regulator ICs manufactured using CMOS process with 28V of operation voltage. The series consists of a voltage reference, an error amplifier, a current limiter, a thermal protection circuit and a phase compensation circuit plus a driver transistor. The output voltage is selectable in 0.1V increments within the range of 1.8V to 18V which fixed by laser trimming technologies. The output stabilization capacitor (CL) is also compatible with low ESR ceramic capacitors. The over current protection circuit and the thermal shutdown circuit are built-in. These two protection circuits will operate when the output current reaches current limit level or the junction temperature reaches temperature limit level. The CE function enables the output to be turned off and the IC becomes a stand-by mode resulting in greatly reduced power consumption. Packages are selectable depending on the applications from SOT-25, SOT-89, SOT-89-5, USP-6C, SOT-223, and TO-252.
