It is the step down converter that switches 1.5V from 5V. 1.5V is used for DDR RAM
supplies. Max 1100 mA current is drawn from IC600.
IC602, IC-SMD XC6221A252GR-G USP-4 T&R, VCC2V5 Linear Regulator
It is the linear regulator to obtain 2.5V from 3.3V. VCC2V5 is used in DVB-T2
demodulator and main IC supplies. Max 150 mA current is drawn from IC602.
IC601, IC-SMD AP2171WG-7 SOT23-5 T&R, VCC3V3 Linear Regulator
It is the linear regulator that creates VCC3V3 from the VCC3V3-ST voltage. VCC3V3
voltage is used in ON-MODE to supply main IC, flash and EEPROM. Max 700 mA
current is drawn from IC601.
IC603, IC-SMD XC6222D501ER-G USP-6C T&R, VCC5V Linear Regulator
In this linear regulator, VCC5V voltage is created. This voltage is used for used for
Tuner and HDMI supplies. VCC5V is made from VCC5V3_FE voltage and
