±1%, Ultra-Low Output Voltage, Dual and Triple Linear n-FET Controllers
General Description
The MAX8563/MAX8564/MAX8564A ultra-low-output dual
and triple LDO controllers allow flexible and inexpensive
point-of-load voltage conversion in motherboards,
desknotes, notebooks, and other applications.
These parts feature a 0.5V reference voltage with ±1%
accuracy providing tight regulation of the output volt-
age. The MAX8563 has three n-channel MOSFET con-
troller outputs, and the MAX8564/MAX8564A has two
controller outputs.
Each controller output is adjustable from 0.5V to 3.3V
when VDD= 12V and between 0.5V and 1.8V when VDD
= 5V. Each output is independently enabled and asserts
a POK signal when the output reaches 94% of the set
value. Each output is protected against a soft short-circuit
condition by an undervoltage comparator that disables
the output when it drops to under 80% of the set voltage
for more than 50µs. For a catastrophic short condition, the
regulators are shut down immediately if the output drops
below 60% of the set voltage.
The MAX8563 is available in a 16-pin QSOP
package, and the MAX8564/MAX8564A are available
in a 10-pin µMAX®package.
