Outline
This IC is a multi-out*
1
150mA regulator with output voltage switching function.
Instead of conventional 2 power supply structure for the 1.8 V
3.3 V output voltage of the SDXC card, it
is now possible to structure with 1 product by the output switching CV terminal, realizing simplifi cation and
low power consumption of the system. It can also support the low power consumption type application by
arbitrary voltage setting.
There are 2 types of output current, 150mA(MM3532T)/500mA(MM3532A), supporting wide range of
applications.
The package has adopted small and high heat dissipation type SSON-6A (1820 size) that is appropriate for
high density implementation.
1 Multi-Out : A function to switch the output voltage value (VOUT) between VOUT- H / VOUT- L by switching the voltage
Low/High applied to the output voltage control terminal (CV).
V
OUT can be set to VOUT- H by setting the CV terminal to Low, and VOUT can be set to VOUT- L by setting
the CV terminal to High.
In case of SDXC card support, it will be V
OUT- H = 3.3 V and VOUT- L = 1.8 V.

When the voltage of the terminal CV is higher than the voltage of the terminal V
DD,
it becomes test mode. In that case, please note that there is a possibility that the
output voltage is turned off.
