XC6701
Series
28V Operation High Speed Voltage Regulators with Stand-by Function
ETR0334-005a
■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 shutdown 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 (C
L
) 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.
