3V.
The AS1320 achieves an efficiency of up to 90%.
The minimum input voltage is 1.
5V, the output voltage is fixed at 3.
3V, and output current is up to 200mA (@ 2V).
In order to save power the AS1320 features a shutdown mode, where it draws less than 1µA.
In shutdown mode the battery is connected directly to the output enabling the supply of real-time-clocks.
The AS1320 provides a power-on reset output that goes high-impedance when the output reaches 90% of its regulation point.
The SHDNN trip threshold of the AS1320 can be used as an input voltage detector that disables the device when the battery voltage falls to a predetermined level.
An internal synchronous rectifier is included, thus an external transistor or Schottky diode is not ...
