HT71XX High Voltage Regulator Features · · · Low power consumption Low voltage drop Low temperature coefficient · · High input voltage (up to 24V) TO-92 and SOT-89 packages · Audio/Video equipment Applications · · Battery-powered equipment Communication equipment General Description Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain variable voltages and currents. The HT71XX series is a set of three-terminal low power high voltage regulators implemented in CMOS technology. They allow input voltages 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.
