Overview
MIC29310/29312 Micrel MIC29310/29312 3A Fast-Response LDO Regulator General Description Features The MIC29310 and MIC29312 are low cost versions of • Low cost versions of MIC29300 family MIC29300 family low-dropout (LDO) regulators.
Manufac• Fast transient response tured on Micrel’s proprietary Super beta PNP™ process, the • 3A current over full temperature range MIC29310/2 is a 3A LDO regulator with very low-dropout • 600mV dropout voltage at full load voltage (600mV over the full load) and low ground current.
• Low ground current Along with a total accuracy of ± 2% (over temperature, line • Accurate 1% guaranteed tolerance and load regulation) these regulators feature very fast tran• “Zero” current shutdown mode (MIC29312) sient recovery from input voltage surges and output load • Fixed voltage and adjustable versions current changes.
Applications The MIC29310 is available in fixed 3.
3V and 5V outputs • Processor peripheral and I/O supplies voltages; the MIC29312 has an adjustable output which can • PC add-in cards be set by two external resistors to a voltage between 1.
24V • High-efficiency “green” computer systems to 15V.
In addition, all versions are fully protected against • High-efficiency linear power supplies overcurrent faults, reversed input polarity, reversed lead • High-efficiency switching supply post regulator insertion, and overtemperature operation.
• Battery-powered equipment A TTL logic enable (EN) pin is available in the MIC29312 to shutdown the regulator.
When not used, the device can be set 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 Ordering Information voltage, input voltage greater than 16V, or an Part Number Voltage Junction Temp.
