MIC29150/29300/29500/29750 High-Current Low-Dropout Regulators General Description Features The MIC29150/29300/29500/29750 are high current, high High current capability: accuracy, low-dropout voltage regulators. Using Micrel s MIC29150/29151/29152/29153.............................. 1.5A proprietary Super eta PNP process with a PNP pass MIC29300/29301/29302/29303................................. 3A element, these regulators feature 350mV to 425mV (full MIC29500/29501/29502/29503................................. 5A load) typical dropout voltages and very low ground current. MIC29750/29751/29752 ......................................... 7.5A Designed for high current loads, these devices also find Low-dropout voltage applications in lower current, extremely low dropout-critical Low ground current systems, where their tiny dropout voltage and ground current values are important attributes. Accurate 1% guaranteed tolerance The MIC29150/29300/29500/29750 are fully protected Extremely fast transient response against overcurrent faults, reversed input polarity, reversed Reverse-battery and Load Dump protection lead insertion, overtemperature operation, and positive Zero-current shutdown mode and negative transient voltage spikes. Five pin fixed (5-pin versions) voltage versions feature logic level ON/OFF control and an Error flag signals output out-of-regulation error flag which signals whenever the output falls out of (5-pin versions) regulation. Flagged states include low input voltage Also characterized for smaller loads with industry- (dropout), output current limit, overtemperature shutdown, leading performance specifications and extremely high voltage spikes on the input. Fixed voltage and adjustable versions On the MIC29xx1 and MIC29xx2, the ENABLE pin may be tied to VIN if it is not required for ON/OFF control. The Applications MIC29150/29300/29500 are available in 3-pin and 5-pin 2 Battery-powered equipment TO-220 and surface mount TO-263 (D Pak) packages. The MIC29750 7.5A regulators are available in 3-pin and High-efficiency Green computer systems 5-pin TO-247 packages. The 1.5A, adjustable output Automotive electronics MIC29152 is available in a 5-pin power D-Pak (TO-252) High-efficiency linear lower supplies package. High-efficiency lost-regulator for switching supply For applications with input voltage 6V or below, see MIC37xxx LDOs.
