MIC29150/29300/29500/29750 Series
High-Current Low-Dropout Regulators
General Description
Features
The MIC29150/29300/29500/29750 are high current, high • High Current Capability
accuracy, low-dropout voltage regulators. Using Micrel's
MIC29150/29151/29152/29153 ................................ 1.5A
proprietary Super ßeta PNP™ process with a PNP pass
MIC29300/29301/29302/29303 ................................... 3A
element, these regulators feature 300mV to 370mV (full load)
MIC29500/29501/29502/29503 ................................... 5A
dropout voltages and very low ground current. Designed for
MIC29750/29751/29752 ........................................... 7.5A
high current loads, these devices also find applications in • Low-Dropout Voltage ....................... 350mV at Full Load
lower current, extremely low dropout-critical systems, where • Low Ground Current
their tiny dropout voltage and ground current values are • Accurate 1% Guaranteed Tolerance
important attributes.
• Extremely Fast Transient Response
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
• Reverse-battery and “Load Dump” Protection
• Zero-Current Shutdown Mode (5-Pin versions)
• Error Flag Signals Output Out-of-Regulation
(5-Pin versions)
• Also Characterized For Smaller Loads With Industry-
Leading Performance Specifications
• Fixed Voltage and Adjustable Versions
