Overview

The 022GF_LDO_01 is capacitor-less Linear Regulator
designed in GlobalFoundries 22FDX to generate
internal supply voltage for core logic domain, SRAM
array or RF/analog domain.
The LDO should be supplied by dual power supply,
0.72V to 1.2V voltage and 1.8V, and can generate
programmable output voltage in the range of 0.5V to
0.8V.
The LDO requires an external voltage reference 0.5V
and embeds voltage-to-current converter for biasing
and logic control.
It features normal and low-power (LP) operating modes
to adjust the amount of output current depending on the
application requirements.
A current limiter signal notifies the system when the
load current exceeds the limit and it starts limiting the
output current.
A Regulation OK (ROK) signal inform the system that
the LDO has completed its booting sequence and if its output is maintaining regulation for the current drawn by the
load.
