摘要
A scan-reconfigurable hybrid low dropout (LDO) macro with four operating modes to support tuning across a wide range of power supply noise rejection and power efficiency is presented. The configurations include: 1) a full-digital LDO; 2) an analog loop in parallel with a digital loop in switched mode control; 3) an analog LDO in parallel with discrete current sources; and 4) discrete current sourc...
