Abstract
Small area LDO (Low drop-out) regulator with pass transistor using body-driven technique is presented in this paper. The body-driven technique can decrease threshold voltage (Vth) and increase the current ID flowing from drain to source in current. The technique is applied to the pass transistor to reduce size of area and maintain the same performance as conventional LDO regulator. A pass transistor using the technique can reduce its size by 5.5 %. The proposed LDO regulator works under the input voltage of 2.7 V ~ 4.5 V and provides up to 150mA load current for an output voltage range of 1.2 V ~ 3.3 V.
