MIC2915X/30X/50X/75X  
High-Current Low Dropout Regulators  
Features  
General Description  
• High Current Capability:  
The MIC2915x/2930x/2950x/2975x are high current,  
high accuracy, low dropout voltage regulators. Using  
Microchip’s proprietary Super βeta PNP process with a  
PNP pass element, these regulators feature 350 mV to  
425 mV (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.  
- MIC29150/29151/29152/29153: 1.5A  
- MIC29300/29301/29302/29303: 3A  
- MIC29500/29501/29502/29503: 5A  
- MIC29751/29752: 7.5A  
• Low Dropout Voltage  
• Low Ground Current  
• Accurate 1% Guaranteed Tolerance  
• Extremely Fast Transient Response  
• Reverse-Battery and “Load Dump” Protection  
• Zero-Current Shutdown Mode (5-Pin Versions)  
The MIC2915x/2930x/2950x/2975x are fully protected  
against overcurrent faults, reversed input polarity,  
reversed lead insertion, overtemperature operation,  
and positive and negative transient voltage spikes. Five  
pin fixed-voltage versions feature logic level ON/OFF  
control and an error flag that signals whenever the  
output falls out of regulation. Flagged states include  
low input voltage (dropout), output current limit,  
overtemperature shutdown, and extremely high voltage  
spikes on the input.  
• 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  
On the MIC29xx1 and MIC29xx2, the ENABLE pin may  
be tied to VIN if it is not required for ON/OFF control.  
The MIC2915x/2930x/2950x are available in 3-pin and  
5-pin TO-220 and surface mount TO-263 (D2Pak)  
packages. The MIC2975x 7.5A regulators are available  
in a 5-pin TO-247 package. The 1.5A, adjustable output  
MIC29152 is available in a 5-pin power D-Pak  
(TO-252) package.  
• High-Efficiency Linear Power Supplies  
• High-Efficiency Post-Regulator for Switching  
Supply  
For applications with input voltage 6V or below, see  
MIC37xxx LDOs.
