MIC29302H

The MIC29302HWU is a high current, high accuracy, lowdropout voltage regulators. Using Micrel's proprietary Super βeta PNP® process with a PNP pass element, these regulators feature 350mV to 425mV (full load) typical dropout voltages and very low ground current. Designed for high current loads, these devices also find applications in lower current, extremely low dropout-critical systems, where their tiny dropout voltage and ground current values are important attributes.

The MIC29302HWU is fully protected against overcurrent faults, reversed input polarity, reversed lead insertion, over-temperature operation, and positive and negative transient voltage spikes. Five pin fixed voltage versions feature logic level ON/OFF control and an error flag which signals whenever the output falls out of regulation. Flagged states include low input voltage (dropout), output current limit, over-temperature shutdown, and extremely high voltage spikes on the input.

The ENABLE pin may be tied to VIN if it is not required for ON/OFF control. The MIC29302HWU is available in a 5-pin surface mount TO-263 (D2Pak) package. For applications with input voltage 6V or below, see MIC37xxx LDOs.
