3. TECHNICAL BRIEF
Table 3.2.2 Voltage regulator summary
1. All regulator names are based on their intended use, though some may be used to power alternate
functions. For example, the USIM regulator is intended to power an external SIM card but may be used to
power other circuits (or not used at all).
2. Each current listed in this table is its regulator's rated value – the current at which the regulator meets all its
performance specifications. Higher currents are allowed, but higher input voltages may be required and
some performance characteristics may become degraded. See the appropriate regulator sections for details.
3. VREG_MSMP powers key internal circuits and should be kept on at its default voltage setting.
4. All regulators have default output voltage settings, even if they default to an off condition.
