converters enter a low-power mode at light load for
maximum efficiency across the widest possible range
(VRTC)
of load currents. The TPS65020 also integrates two
2 × 200 mA LDO for SRAM and PLL
200-mA LDO voltage regulators, which are enabled

with an external input pin. Each LDO operates with
Core
an input voltage range between 1.5 V and 6.5 V,
allowing them to be supplied from one of the
Externally Adjustable Reset Delay Time
