2019-9-17 · LDO is a part of linear regulator dynasty. But unlike normal Linear regulators in an LDO the difference between the input voltage and the output voltage is less. This difference is called as dropout voltage. Since the LDO has very low dropout voltage it is called as Low dropout voltage regulators.
LDO s supply current is an operating current for the LDO itself. It does not include the current supplied to or driving other devices. As for the input current 100 load current also flows from input power source. In a CMOS-based linear regulator as shown in the figure 1 the supply current is flowing to the LDO controlling circuit equal to
A low dropout (LDO) linear voltage regulator is a type of linear voltage regulator circuit that works well even when the output voltage is very close to the input voltage improving its power efficiency.
2011-8-6 · Dropout voltage is the input-to-output differential voltage at which the circuit ceases to regulateagainst further reductions in input voltage this point occurs when the input voltage approachesthe output voltage. Figure 1 shows a typical LDO regulator circuit. In the dropout region thePMOS pass element is simply a resistor and dropout is expressed in terms of its on-resistance(Ron).
