General Description

Features

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.

♦ MAX8563: 3 Outputs

♦ MAX8564/MAX8564A: 2 Outputs

♦ ±±1 ꢀFFedbac ꢁFꢂuꢃbtꢄio

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.

when V

= ±2V and between 0.5V and ±.8V when V

SFquFoaꢄoꢂ

= 5V. Each output is independently enabled and asserts

a POK signal when the output reaches 941 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 801 of the set voltage

for more than 50µs. For a catastrophic short condition, the

regulators are shut down immediately if the output drops

below 601 of the set voltage.
