AAT3242
300mA/150mA Dual CMOS LDO Linear Regulator
3242.2006.04.1.10

Functional Description
The AAT3242 is a high performance dual LDO reg-
ulator with two Power OK pins. The first regulator
(A) sources 300mA of current, while the second (B)
regulator can deliver 150mA. Each regulator has
an integrated Power OK comparator which indi-
cates when the respective output is out of regula-
tion. The POK pins are open drain outputs, and
they are held low when the respective regulator is
in shutdown mode.
The device has independent enable pins to shut
down each LDO regulator for power conservation
in portable products. Forcing EN A/B low (<0.6V)
powers down the regulators and draws a maximum
of 1.0μA. The AAT3242 has short-circuit and ther-
mal protection in case of adverse operating condi-
tions. Device power dissipation is limited to the
package type and thermal dissipation properties.
Refer to the Thermal Considerations section of this
datasheet for details on device operation at maxi-
mum output current loads.
