DESCRIPTION
The IXD1216 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 2.0 V to 12 V for B and D series
and from 2.0 V to 23 V with external resistors for C
series. High precision output voltage achieved by
laser trimming technology.
The IXD1216 is stable with low ESR ceramic output
capacitor (C
L
). 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 IXD1216
into standby mode, reducing current consumption to
less than 0.1 µA typically.
The IXD1216 is available in SOT-25, SOT-89, SOT-
89-5, SOP-8FD, USP-6C, SOT-223, and TO-252
packages.
