|he MIC29302WU is a high current, high accuracy, low-dropout voltage regulator. Using Micrel's proprietary Super ?eta PNP? process with a PNP pass element, these regulators feature 350 mV to 425 mV (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 MIC29302WU is fully protected against overcurrent faults, reversed input polarity, reversed lead insertion, overtemperature 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, overtemperature shutdown, and extremely high voltage spikes on the input. On the MIC29xx1 and MIC29xx2, the ENABLE pin may be tied to VIN if it is not required for ON/OFF control. The MIC29150/29300/29500 are available in 3-pin and 5-pin TO-220 and surface mount TO-263 (D2Pak) packages. The MIC29750 7.5 A regulators are available in 3-pin and 5-pin TO-247 packages. The 1.5 A, adjustable output MIC29152 is available in a 5-pin power D-Pak (TO-252) package.
