TX71XXH General Description:
The TX71XXH series is a set of three-terminal low power high voltage regulators implemented in CMOS technology. They allow input voltages as high as 32V. They are available with several fixed output voltages ranging from 2.5V 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.
TX71XXH Features:
Low power consumption
Low voltage drop
Low temperature coefficient
High input voltage (up to 32V)
Output voltage accuracy: tolerance ±3%
TO92 and SOT89 package
TX71XXH Applications:
Battery-powered equipment
Communication equipment
Audio/Video equipment
