General Description
The MIC69101/103 is the 1A output current member of the
MIC69xxx family of high current, low voltage regulators,
which support currents of 1A, 1.5A, 3A, and 5A. The
MIC69101/103 operates from a single low voltage supply,
yet offers high precision and ultra-low dropout of 500mV
under worst case conditions.
The MIC69101/103 operates from an input voltage of
1.65V to 5.5V. It is designed to drive digital circuits
requiring low voltage at high currents (i.e. PLDs, DSP,
microcontroller, etc.). These regulators are available in
adjustable and fixed output voltages including 1.8V. The
adjustable version can support output voltages down to
0.5V.
The
Cap design of the MIC69101/103 is optimized for
stability with low value low-ESR ceramic output capacitors.
Features of the MIC69101/103 include thermal shutdown
and current limit protection. Logic enable and error flag
pins are also available.
The MIC69101/103 is offered in a tiny 10-pin 3mm x 3mm
MLF
package and has an operating temperature range of
–40°C to +125°C.
Datasheets and support documentation can be found on
Micrel’s web site at: www.micrel.com.
