PRODUCTION DATA
Typically powered from the BUCK6 output, the VTT LDO tracks FBVOUT6 and regulates it's output to FBVOUT6 / 2. The LDO current limit is OTP dependent, and it is designed specifically to power DDR memory. The LDO core is a transconductance amplifier with large gain, and it drives a current output stage that either sources or sinks current depending on the deviation of the VTTFB pin voltage from the target regulation voltage.
