LDOs minimise external components and maximise battery lifetime

The AS1360 family of LDO voltage regulators from austriamicrosystems is capable of producing a stable output voltage using a 1µF ceramic output capacitor, to save cost and footprint in portable and batterypowered equipment.

With an extremely low quiescent current of 1.5µA and low drop-out voltage of 400mV, these devices also help to extend battery life and are ideal for applications which are always on.

A variety of fixed output voltages are available, accurate to within ±1.5%. The available voltages are 1.8V, 2.5V, 3.0V, 3.3V and 5.0V.

The devices are also capable of delivering up to 250mA of output current. Combined with a high input voltage of up to 20V, this enables the AS1360 to drive applications with a high input-to-output voltage differential.

Integrated short-circuit and over-current protection also save part count and board space, enabling a compact and efficient solution.
