MIC29150/29300/29500/29750 Series
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 eta PNP process with a PNP pass
element, these regulators feature 300mV to 370mV (full load)
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 nega-
tive 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 V
IN
if it is not required for ON/OFF control. The
MIC29150/29300/29500 are available in 3- and 5-pin TO-220
and surface mount TO-263 packages. The MIC29750 7.5A
regulators are available in 3- and 5-pin TO-247 packages.
