Description
The ZXTR2008P5 monolithically integrates a transistor, Zener diode
and resistor to function as a high voltage linear regulator. The device
regulates with an 8.2V 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 PowerDI-5 package,
minimizing PCB area and reducing number of components when
compared with a multi-chip discrete solution.
Applications
Supply voltage regulation in:
Networking
Telecom
Power Over Ethernet (PoE)
