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.
