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 VIN 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 (D2Pak)
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.
