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.
