MIC29510/29512  
5A Fast-Response LDO Regulator  
Preliminary Information  
General Description  
Features  
The MIC29510 and MIC29512 are high-current, high-accu-  
racy, low-dropout voltage regulators featuring fast transient  
recovery from input voltage surges and output load current  
changes. These regulators use a PNP pass element that  
features Micrel’s proprietary Super ßeta PNP™ process.  
• Fast transient response  
• 5A current capability  
• 700mV dropout voltage at full load  
• Low ground current  
• Accurate 1% guaranteed tolerance  
• “Zero” current shutdown mode (MIC29512)  
• Fixed voltage and adjustable versions  
The MIC29510/2 is available in two versions: the three pin  
fixed output MIC29510 and the five pin adjustable output  
voltage MIC29512. All versions are fully protected against  
overcurrent faults, reversed input polarity, reversed lead  
insertion, overtemperatureoperation, andpositiveandnega-  
tive transient voltage spikes.  
Applications  
• Pentium™ and Power PC™ processor supplies  
• High-efficiency “green” computer systems  
• High-efficiency linear power supplies  
• High-efficiency switching supply post regulator  
• Battery-powered equipment  
A TTL compatible enable (EN) control pin supports external  
on/off control. If on/off control is not required, the device may  
be continuously enabled by connecting EN to IN.  
The MIC29510/2 is available in the standard three and five  
pin TO-220 package with an operating junction temperature  
range of 0°C to +125°C.  
For applications requiring even lower dropout voltage, input  
voltage greater than 16V, or an error flag, see the MIC29500/  
29501/29502/29503.
