General Description
The MIC29150/29300/29500/29750 are high current, high accuracy,
low-dropout voltage regulators. Using Micrels 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.
