HT75XX-1
100mA Low Power LDO
Features
· Low power consumption
· High output current : 100mA (Pd £ 250mW)
· Low voltage drop
· Output voltage accuracy: tolerance ±3%
· Low temperature coefficient
· TO-92, SOT-89 and SOT-25 package
· High input voltage (up to 24V)

General Description
Although designed primarily as fixed voltage regulators,
these devices can be used with external components to
obtain variable voltages and currents.
The HT75XX-1 series is a set of three-terminal high current low voltage regulator implemented in CMOS technology. They can deliver 100mA output current and
allow an input voltage as high as 24V. They are available with several fixed output voltages ranging from
3.0V to 5.0V. CMOS technology ensures low voltage
drop and low quiescent current.
