GENERAL DESCRIPTION
The ADP3302 is a member of the ADP330X family of precision
micropower low dropout anyCAP regulators. The ADP3302
contains two fully independent 100 mA regulators with separate
shutdown and merged error outputs. It features 1.4% overall
output accuracy and very low, 120 mV typical, dropout voltage.
The ADP3302 has a wide input voltage range from
1
3 V to
1
12 V. It features an error flag that signals when either of the
two regulators is about to lose regulation. It has short circuit
current protection as well as thermal shutdown.
The ADP3302’s enhanced lead frame design allows for a maxi-
mum power dissipation of 630 mW @ +70
°
C ambient temperature
and 1.0 W at room temperature without any external heat sink.
