MIC29310/29312  
3A Fast-Response LDO Regulator  
General Description  
Features  
The MIC29310 and MIC29312 are low cost versions of  
MIC29300 family low-dropout (LDO) regulators. Manufac-  
tured on Micrel’s proprietary Super beta PNP™ process,  
the MIC29310/2 is a 3ALDO regulator with very low-dropout  
voltage (600mV over the full load) and low ground current.  
Along with a total accuracy of ±2% (over temperature, line  
and load regulation) these regulators feature very fast tran-  
sient recovery from input voltage surges and output load  
current changes.  
• Low cost versions of MIC29300 family  
• Fast transient response  
• 3A current over full temperature range  
• 600mV dropout voltage at full load  
• Low ground current  
• Accurate 1% guaranteed tolerance  
• “Zero” current shutdown mode (MIC29312)  
• Fixed voltage and adjustable versions  
Applications  
• Processor peripheral and I/O supplies  
• PC add-in cards  
• High-efficiency “green” computer systems  
• High-efficiency linear power supplies  
• High-efficiency switching supply post regulator  
• Battery-powered equipment  
The MIC29310 is available in fixed 3.3V and 5V outputs  
voltages; the MIC29312 has an adjustable output which can  
be set by two external resistors to a voltage between 1.24V  
to 15V. In addition, all versions are fully protected against  
overcurrent faults, reversed input polarity, reversed lead  
insertion, and overtemperature operation.  
A TTL logic enable (EN) pin is available in the MIC29312 to  
shutdowntheregulator. Whennotused,thedevicecanbeset  
to continuous operation by connecting EN to the input (IN).  
The MIC29310/2 is available in the standard 3- and 5-pin  
TO-220 and TO-263 packages 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 MIC29300/29301/29302/  
29303.
