General Description
The MIC37501 and MIC37502 are 5A, low dropout
linear voltage regulator that provide low voltage, high
current outputs with a minimum of external components.
They offer high precision, ultra-low dropout (500mV),
and low ground current.
The MIC37501and MIC37502 operate from an input of
2.3V to 6.0V. They are designed to drive digital circuits
requiring low voltage at high currents (i.e., PLDs, DSPs,
microcontrollers, etc.). They are available in fixed and
adjustable output voltages. Fixed voltages include 1.5V,
1.65V, 1.8V, 2.5V, and 3.3V. The adjustable version is
capable of 1.24V to 5.5V.
MIC37501 and MIC37502 LDOs feature thermal and
currentlimit protection and reverse current protection.
Logic enable and error flag pins are available.
Junction temperature range of the MIC37501/02 is from
–40°C to 125°C.
For applications requiring input voltage greater than
6.0V, see MIC3910x, MIC3915x, MIC3930x, and
MIC3950x LDOs.
