MIC29302A 3A Fast Response LDO Regulator Features General Description High-Current Capability The MIC29302A is a high-current, low-dropout voltage regulator that uses Microchip s proprietary Super eta Operating Input Voltage Range: 3V to 16V PNP process with a PNP pass element. The 3A LDO Low Dropout Voltage regulator features 560 mV (full load) dropout voltage Low Ground Current and very low ground current. Designed for high-current Accurate 1% Tolerance loads, these devices also find applications in lower Fast Transient Response current, low-dropout critical systems, where their dropout voltages and ground current values are 1.24V to 15V Adjustable Output Voltage important attributes. Packages: TO-263-5L and TO-252-5L Along with a total accuracy of 2% (over temperature, Applications line, and load regulation) the regulator features very Processor Peripheral and I/O Supplies fast transient recovery from input voltage surges and High-Efficiency Green Computer Systems output load current changes. Automotive Electronics The MIC29302A has an adjustable output that can be High-Efficiency Linear Lower Supplies set by two external resistors to a voltage between 1.24V and 15V. In addition, the device is fully protected Battery-Powered Equipment against overcurrent faults, reversed input polarity, PC Add-In Cards reversed lead insertion, and overtemperature High-Efficiency Post-Regulator for Switching operation. A TTL/CMOS logic enable (EN) pin is Supply available in the MIC29302A to shutdown the regulator. When not used, the device can be set to continuous operation by connecting EN to the input (IN). The MIC29302A is available in the standard and 5-pin TO-263 and TO-252 packages with an operating junction temperature range of 40C to +125C.
