Abstract:
A middle-range (mid) low dropout (LDO) voltage has both sinking and sourcing current capability. The mid LDO can provide a voltage reference in active mode and power mode for core only design to work in a Safe Operating Area (SOA). The output of mid LDO can track TO power and/or core power dynamically. The mid LDO can comprise a voltage reference generator and a power-down controller connected to an amplifier, which output is connected to a decoupling capacitor. The provision of a high ground signal allows the mid LDO provide the sinking and sourcing currents.
