1 General Description
The AS1372 is a Dual Supply Rail Linear Regulator
designed for providing ultra-low voltages.
In a typical application the battery is directly connected
to V
Converter.
The very low quiescent currents together with the
excellent transient features and the superior dropout are
making the AS1372 an ideal device for applications
running on batteries.
The robust design ensures that no under-voltage failure
can occur and the device is also equipped with an
internal protection against over-temperature and over-
current.
The device is available in fixed output voltages from
0.5V up to 2.2V in 100mV steps (50mV from 0.5V to
1.1V).
The AS1372 is available in a 5-bumps CS-WLP package
and is qualified for -40°C to +85°C operation.
