LD6356

Preliminary – LD6356 Low-Dropout Regulators Features  High current capability: 1.5a  Low-dropout voltage: 350mv  Low ground current  Accurate 1% guaranteed tolerance  Extremely fast transient response  Reverse-battery and “load dump” protection  Zero-current shutdown mode (5-pin versions)  Error flag signals output out-of-regulation (5-pin versions)  Also characterized for smaller loads with industry- leading performance specifications  Fixed voltage and adjustable versions Applications  Battery powered equipment  High-efficiency “green” computer systems  Automotive electronics  High-efficiency linear power supplies  High-efficiency post-regulator for switching supply General Description The LD6356 are high current, high accuracy, lowdropout voltage regulators. Using process with a PNP pass element, these regulators feature 350mV (full load) dropout voltages and very low ground current. These devices also find applications in lower current, low dropout-critical systems, where their tiny dropout voltage and ground current values are important attributes. The LD6356 are fully protected against over current faults, reversed input polarity, reversed lead insertion, over temperature 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. On the MIC29151 and MIC29152, the ENABLE pin maybe tied to VIN if it is not req...
