General Description
Features
The MIC69301/2/3 is the 3A output current member of the
MIC69xxx family of high current, low voltage regulators,
which support currents of 1A, 1.5A, 3A, and 5A. This
family operates from a single low voltage supply, yet offers
high precision and ultra low dropout of 500mV under worst
case conditions.
The MIC69301/2/3 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. The adjustable version can support
output voltages down to 0.5V.
The µCap design of the MIC69301/2/3 is optimized for
stability with low value low-ESR ceramic output capacitors.
• Input voltage range: V_IN: 1.65V to 5.5V
• Maximum dropout (V_IN – V_OUT) of 500mV
over temperature
• Adjustable output voltage down to 0.5V
• Stable with 10µF ceramic output capacitor
• Excellent line and load regulation
• Logic controlled shutdown
• Thermal shutdown and current-limit protection
• 5-Pin TO-263
• 5-Pin S-Pak package
• EPAD SOIC-8 package
• –40°C to +125°C junction temperature range
Features of the MIC69301/2/3 include thermal shutdown
and current limit protection. Logic enable and error flag
pins are also available.
The MIC69301/2/3 is offered in TO-263, S-PAK and the
EPAD SOIC-8 packages. All packages have an operating
temperature range of –40°C to +125°C.
Applications
• Point-of-load applications
