Description
Features
Diodes Incorporated
ZXTR1005K4
The ZXTR1005K4 is a high voltage regulator with fixed output voltage
of 5V ± 2% and a 50mA drive capability. It is designed for use in high
voltage applications where standard linear regulators cannot be used.
This function is fully integrated into a TO252 package, minimizing
PCB area and reducing number of components when compared with
a multi-chip discrete solution.
The device also features an enable pin which disables the regulator
when pulled low.
Applications
Supply voltage regulation in:
• Networking
• Telecom
• Power Over Ethernet (PoE)
