MIC29150/29300/29500/29750  
High-Current Low-Dropout Regulators  
General Description  
Features  
The MIC29150/29300/29500/29750 are 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.  
High current capability:  
MIC29150/29151/29152/29153..............................1.5A  
MIC29300/29301/29302/29303.................................3A  
MIC29500/29501/29502/29503.................................5A  
MIC29750/29751/29752.........................................7.5A  
Low-dropout voltage  
Low ground current  
Accurate 1% guaranteed tolerance  
Extremely fast transient response  
Reverse-battery and “Load Dump” protection  
The MIC29150/29300/29500/29750 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 which 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.  
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  
On the MIC29xx1 and MIC29xx2, the ENABLE pin may be  
tied to VIN if it is not required for ON/OFF control. The  
MIC29150/29300/29500 are available in 3-pin and 5-pin  
TO-220 and surface mount TO-263 (D2Pak) packages.  
The MIC29750 7.5A regulators are available in 3-pin and  
5-pin TO-247 packages. The 1.5A, adjustable output  
MIC29152 is available in a 5-pin power D-Pak (TO-252)  
package.  
Applications  
Battery-powered equipment  
High-efficiency “Green” computer systems  
Automotive electronics  
High-efficiency linear lower supplies  
High-efficiency lost-regulator for switching supply  
For applications with input voltage 6V or below, see  
MIC37xxx LDOs.
