AS1370
High Voltage, Low Quiescent Current,
200mA LDO
General Description
The AS1370 low-power, positive voltage regulator is designed
to deliver up to 200mA, while consuming only 3μA of quiescent
current. The device is available in fixed output voltages
between 1.2V and 5.5V (programmable in 100mV steps).
Standard options of 1.2, 1.8, 2.5, 3.0, 3.3, 4.5, 5.0 and 5.5V are
also available. The input voltage ranges from 2.6V to a
maximum of 50V. Operation with large input to output
differential voltages is limited by the maximum power
dissipation available from package and environment.
The very-low dropout voltage (550mV @ 200mA load) prolongs
battery life and allows high current in small applications with
minimum input-to-output voltage differentials. The device
features very stable output voltage (using only 1μF ceramic
capacitor), and excellent line- and load-regulation. The AS1370
also features a Power-OK Output. The device features
integrated short-circuit and over current protection. Thermal
Protection shuts down the device when die temperature
reaches 170°C. This is a useful protection when the device is
under sustained short circuit conditions.
The AS1370 is available in an 8-Pin MLPD 3mm x 3mm package
and is qualified for -40°C to 125°C operation.
