MIC2915X/30X/50X/75X High-Current Low Dropout Regulators Features General Description High Current Capability: The MIC2915x/2930x/2950x/2975x are high current, high accuracy, low dropout voltage regulators. Using - MIC29150/29151/29152/29153: 1.5A Microchips proprietary Super eta PNP process with a - MIC29300/29301/29302/29303: 3A PNP pass element, these regulators feature 350 mV to - MIC29500/29501/29502/29503: 5A 425 mV (full load) typical dropout voltages and very low - MIC29751/29752: 7.5A ground current. Designed for high current loads, these Low Dropout Voltage devices also find applications in lower current, Low Ground Current extremely low dropout-critical systems, where their tiny dropout voltage and ground current values are Accurate 1% Guaranteed Tolerance important attributes. Extremely Fast Transient Response The MIC2915x/2930x/2950x/2975x are fully protected Reverse-Battery and Load Dump Protection against overcurrent faults, reversed input polarity, Zero-Current Shutdown Mode (5-Pin Versions) reversed lead insertion, overtemperature operation, Error Flag Signals Output Out-of-Regulation and positive and negative transient voltage spikes. Five (5-Pin Versions) pin fixed-voltage versions feature logic level ON/OFF Also Characterized for Smaller Loads with control and an error flag that signals whenever the Industry-Leading Performance Specifications output falls out of regulation. Flagged states include Fixed-Voltage and Adjustable Versions low input voltage (dropout), output current limit, overtemperature shutdown, and extremely high voltage Applications spikes on the input. Battery-Powered Equipment On the MIC29xx1 and MIC29xx2, the ENABLE pin may High-Efficiency Green Computer Systems be tied to V if it is not required for ON/OFF control. IN Automotive Electronics The MIC2915x/2930x/2950x are available in 3-pin and 2 5-pin TO-220 and surface mount TO-263 (D Pak) High-Efficiency Linear Power Supplies packages. The MIC2975x 7.5A regulators are available High-Efficiency Post-Regulator for Switching in a 5-pin TO-247 package. The 1.5A, adjustable output Supply MIC29152 is available in a 5-pin power D-Pak (TO-252) package. For applications with input voltage 6V or below, see MIC37xxx LDOs.
