ZXTR2005ZQ
100V INPUT, 5V 30mA REGULATOR TRANSISTOR
Description
Features
Series Linear Regulator Using Emitter-Follower Stage
Input Voltage = 10V to 100V (For Regulated Output Voltage)
Output Voltage = 5V ± 10%
The ZXTR2005ZQ monolithically integrates a transistor, Zener diode
and resistor to function as a high voltage linear regulator. The device
regulates with a 5V nominal output at 15mA. It is designed for use in
high voltage applications where standard linear regulators cannot be
used. This function is fully integrated into a SOT89 package,
minimizing PCB area and reducing number of components when
compared with a multi-chip discrete solution.
150kΩ Resistor to Limit Quiescent Current
Fully Integrated Into a SOT89 Package
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
Halogen and Antimony Free. “Green” Device (Note 3)
The ZXTR2005ZQ is suitable for automotive applications
requiring specific change control; this part is AEC-Q101
qualified, PPAP capable, and manufactured in IATF 16949
certified facilities.
