MIC29302HWU  
High-Current Low-Dropout Regulators  
Features  
General Description  
3A current capability  
Low-dropout voltage  
Low ground current  
Accurate 1% guaranteed tolerance  
Extremely fast transient response  
Reverse-battery and “Load Dump” protection  
Zero-current shutdown mode  
Error flag signals output out-of-regulation  
The MIC29302HWU is a high current, high accuracy, low-  
dropout voltage regulators. Using Micrel's proprietary  
Super βeta PNP® process with a PNP pass element, these  
regulators feature 350mV to 425mV (full load) typical  
dropout voltages and very low ground current. Designed  
for high current loads, these devices also find applications  
in lower current, extremely low dropout-critical systems,  
where their tiny dropout voltage and ground current values  
are important attributes.  
Also characterized for smaller loads with industry-  
The MIC29302HWU is fully protected against overcurrent  
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.  
Flagged states include low input voltage (dropout), output  
current limit, over-temperature shutdown, and extremely  
high voltage spikes on the input.  
leading performance specifications  
Applications  
Battery-powered equipment  
High-efficiency “Green” computer systems  
Automotive electronics  
High-efficiency linear power supplies  
High-efficiency post-regulator for switching supply  
The ENABLE pin may be tied to VIN if it is not required for  
ON/OFF control. The MIC29302HWU is available in a 5-  
pin surface mount TO-263 (D2Pak) package.  
For  
applications with input voltage 6V or below, see MIC37xxx  
LDOs.
