General Description

The HT75XX-1 series is a set of three-terminal high cur-

rent low voltage regulator implemented in CMOS tech-

nology. They can deliver 100mA output current and

allow an input voltage as high as 24V. They are avail-

able with several fixed output voltages ranging from

3.0V to 5.0V. CMOS technology ensures low voltage

drop and low quiescent current.

Although designed primarily as fixed voltage regulators,

these devices can be used with external components to

obtain variable voltages and currents.
