AS1364
1A Low Dropout Linear Voltage Regulator
Datasheet
www.austriamicrosystems.com
Revision 1.8
1 - 19
1 General Description
The AS1364 is a low-dropout linear regulator (LDO) designed to
operate from 2V to 5.5V input, that delivers a wide range of highly
accurate (±0.75%) factory-trimmed output voltages as well as
adjustable output voltages (using an external resistor-divider
network).
The ultra-low dropout device requires only 140mV dropout voltage
while delivering a guaranteed 1A load current and is therefore
perfectly suited for battery-operated portable applications.
Additionally the AS1364 offers extremely low 10μV
RMS
(100Hz to
100kHz) or 45μV
RMS
(10Hz to 1MHz) output voltage noise.
The device features an internal PMOS pass transistor (for a low
supply current of only 35μA), reset output, a low-power shutdown
mode, and protection from short-circuit and thermal-overload
conditions.
When in shutdown, a 5k
(typ) discharge path is connected
between the output pin and ground. The AS1364 is available in a
8-pin TDFN 3x3mm package.
