General Description
The HT74XX series is a set of three-terminal
high current high voltage regulator imple-
mented in CMOS technology. They can deliver
100mA output current and allow an input volt-
age as high as -24V. They are available with
several fixed output voltages ranging from
-2.4V to -15V. CMOS technology ensures low
voltage drop and low quiescent current.
Although designed primarily as fixed voltage
regulators, these devices can be used with ex-
ternal components to obtain variable voltages
and currents.
