General Description
The Micrel MIC37300/01/02/03 is a 3.0A low-dropout
linear voltage regulator that provides a low-voltage,
high-current output with a minimum number of external
components. It offers high precision, ultra-low-dropout
(500mV overtemperature), and low-ground current.
The MIC37300/01/02/03 operates from an input of
2.25V to 6.0V. It is designed to drive digital circuits
requiring low-voltage at high currents (i.e., PLDs, DSP,
microcontroller, etc.). It is available in xed and
adjustable output voltages. Fixed voltages include 1.5V,
1.8V, 2.5V and 3.3V. The adjustable version is capable
of 1.24V to 5.5V.
Features of the MIC37300/01/02/03 LDO include
thermal and current-limit protection, and reverse-current
protection. Logic enable and error ag pins are available
on the 5-pin version.
Junction temperature range of the MIC37300/01/02/03
is from–40°C to +125°C.
For applications requiring input voltage greater than
6.0V, see the MIC3910x, MIC3915x, MIC3930x, and
MIC3950x LDOs.
