MIC29150/29300/29500/29750
High-Current Low-Dropout Regulators
General Description
The MIC29150/29300/29500/29750 are high current, high
accuracy, low-dropout voltage regulators. Using Micrel's
proprietary Super
βeta
PNP
®
process with a PNP pass
element, these regulators feature 350mV to 425mV (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 MIC29150/29300/29500/29750 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 which 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
MIC29150/29300/29500 are available in 3-pin and 5-pin
TO-220 and surface mount TO-263 (D
2
Pak) packages.
The MIC29750 7.5A regulators are available in 3-pin and
5-pin TO-247 packages. 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.
