General Description

The MIC2915x/2930x/2950x/2975x are high current,

high accuracy, low dropout voltage regulators. Using

Microchip’s proprietary Super

βeta

PNP process with a

PNP pass element, these regulators feature 350 mV to

425 mV (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.

The MIC2915x/2930x/2950x/2975x 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 that 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.

On the MIC29xx1 and MIC29xx2, the ENABLE pin may

be tied to V

if it is not required for ON/OFF control.

The MIC2915x/2930x/2950x are available in 3-pin and

5-pin TO-220 and surface mount TO-263 (D

Pak)

packages. The MIC2975x 7.5A regulators are available

in a 5-pin TO-247 package. The 1.5A, adjustable output

MIC29152 is available in a 5-pin power D-Pak

(TO-252) package.

For applications with input voltage 6V or below, see

MIC37xxx LDOs.
