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.
HT75XX
High Driver Regulator
High input voltage (up to 24V)
·
High output current : 100mA (Pd£ 250mW)
·
TO-92 and SOT-89 package
·
Audio/Video equipment
·
Although designed primarily as fixed voltage
regulators, these devices can be used with ex
ternal components to obtain variable voltages
and currents.
