General Description Features
The MIC69301/2/3 is the 3A output current member of the
Input voltage range: V : 1.65V to 5.5V
IN
MIC69xxx family of high current, low voltage regulators,
Maximum dropout (V V ) of 500mV
IN OUT
which support currents of 1A, 1.5A, 3A, and 5A. This
over temperature
family operates from a single low voltage supply, yet offers
Adjustable output voltage down to 0.5V
high precision and ultra low dropout of 500mV under worst
Stable with 10F ceramic output capacitor
case conditions.
Excellent line and load regulation
The MIC69301/2/3 operates from an input voltage of 1.65V
to 5.5V. It is designed to drive digital circuits requiring low Logic controlled shutdown
voltage at high currents (i.e., PLDs, DSP, microcontroller,
Thermal shutdown and current-limit protection
etc.). These regulators are available in adjustable and
Error flag output
fixed output voltages. The adjustable version can support
5-Pin TO-263
output voltages down to 0.5V.
5-Pin S-Pak package
The Cap design of the MIC69301/2/3 is optimized for
ePad SOIC-8 package
stability with low value, low-ESR ceramic output
TM
capacitors.
12-Pin 4mm x 4mm MLF package (MIC69303 only)
Features of the MIC69301/2/3 include thermal shutdown
40C to +125C junction temperature range
and current limit protection. Logic enable and error flag
pins are also available.
Applications
The MIC69301/2/3 is offered in TO-263, S-PAK and the
Point-of-load applications
ePad SOIC-8 packages. The MIC69303 is also available in
TM
a 12-Pin 4mm x 4mm MLF package. All packages have
Industrial power
an operating temperature range of 40C to +125C.
