摘要： A low-dropout (LDO) voltage regulator for generating an output voltage is disclosed. The voltage regulator includes a startup circuit, a curvature corrected bandgap circuit, an error amplifier, a metal oxide semiconductor (MOS) pass device and a voltage slew rate efficient transient response boost circuit. The MOS pass device has a gate node which is coupled to the output of the error amplifier, and a drain node for generating the output voltage. The voltage slew rate efficient transient response boost circuit applies a voltage to the gate node of the MOS pass device to accelerate the response time of the error amplifier in enabling the LDO voltage regulator to reach its final regulated output voltage when an output voltage drop occurs in the LDO voltage regulator.

摘要： An electrostatic discharge protection circuit comprises a comparator coupled between a power supply terminal and ground. The comparator responds to an electrostatic discharge event producing a trigger signal at a comparator output. The comparator comprises a first and second current mirror. The first and second current mirrors each comprise a sense device and a mirror device. The mirror devices are coupled in series between the power supply terminal and ground. The first mirror device produces an incident current and the second mirror device receives an absorption current. With a supply voltage on the power supply terminal equal to or greater than a trigger supply voltage, the absorption current exceeds the incident current and produces a trigger signal at the comparator output. The trigger signal activates a shunt device that shunts current from the power supply terminal to ground.
