DESCRIPTION

The IXD1701 is positive voltage regulator with

operation voltage up to 28V, manufactured by CMOS

process.

The IC consists of a voltage reference, an error

amplifier, a current limiter, a thermal protection, a

phase compensation circuit, and a driver transistor.

The output voltage is selectable in 0.1 V increments

within the range from 1.8 V to 18 V. High precision

output

voltage

achieved

by

laser

trimming

technology.

The IXD1701 is stable with low ESR ceramic output

capacitor (CL). The over current protection circuit and

the

thermal

shutdown

are

built-in.

These

two

protection circuits operate when the output current

reaches current limit level or the junction temperature

reaches temperature limit.

The Chip Enable (CE) function allows set IXD1701

into standby mode, reducing current consumption to

less than 0.1 µA typically.

The IXD1701 is available in SOT-25, SOT-89, SOT-

89-5, USP-6C, SOT-223, and TO-252 packages.
