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.
HT75XX-1
100mA Low Power LDO
·
High output current : 100mA (Pd£ 250mW)
·
Output voltage accuracy: tolerance ±3%
·
TO-92, SOT-89 and SOT-25 package
·
Audio/Video equipment
Although designed primarily as fixed voltage regulators,
these devices can be used with external components to
obtain variable voltages and currents.
