General Description
The HT75XX series is a set of three-terminal
high current low 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 sev-
eral fixed output voltages ranging from 3.0V to
8V. 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.
