Hot-selling and scarce MIC29302MU 3A Fast-Response LDO Regulator TO263 spot stock

Product Descriptions

The MIC29302 is a high-current, low-cost, low-dropout  voltage regulator which uses Micrel's proprietary Super  βeta PNP® process with a PNP pass element. The 3A  LDO regulator features 450mV (full load) dropout voltage  and very low ground current. Designed for high-current  loads, these devices also find applications in lower current,  low dropout-critical systems, where their dropout voltage  and ground current values are important attributes.

Along with a total accuracy of ±2% (over temperature, line  and load regulation) the regulator features very-fast  transient recovery from input voltage surges and output  load current changes.

The MIC29302 has an adjustable output which can be  set by two external resistors to a voltage between 1.24V to  15V. In addition, the device is fully protected against over  current faults, reversed input polarity, reversed lead  insertion, and overtemperature operation. A TTL logic  enable (EN) pin is available in the MIC29302 to  shutdown the regulator. When not used, the device can be  set to continuous operation by connecting EN to the input (IN). The MIC29302 is available in the standard and 5-pin  TO-263 and TO-220 packages with an operating junction temperature range of −40°C to +85°C.
