... General Description The AS1372 is a Dual Supply Rail Linear Regulator designed for providing ultra-low voltages typical application the battery is directly connected to V and V is connected to the output of a DC-DC BIAS IN 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 ...

... AS1372 Datasheet - Detailed Description The AS1372 is a low-dropout, low-quiescent-current linear regulator intended for LDO regulator applications where output current load requirements range from no load to 350mA. All devices come with fixed output voltage from 0.5V to 2.2V. (see Ordering Information on page Shutdown current for the whole regulator is typically 10nA. The device features integrated short-circuit and over current protection. Under-Voltage lockout prevents erratic operation when the input voltage is slowly decaying (e. battery powered application). Thermal Protection shuts down the device when die temperature reaches 150° ...

... Thus, even at very small output voltage, the drain to source voltage can be made quite small and guarantee optimal efficiency performance. For instance, by setting Vin at 800mV makes more than 60% efficiency for an output voltage as small as 500mV still ensuring excellent analog performances in the LDO. www.austriamicrosystems.com/LDOs/AS1372 Dual Supply V ...

... LDO until it is amplified to the gate of the output PMOS by the error amplifier. A delay comes, unavoidably. On the contrary, in the dual supply approach it is the source of the output transistor to be coincident with the output voltage. In this way a change in the output voltage immediately modulates the current from the LDO and a better regulation in fast load transient is achieved. www.austriamicrosystems.com/LDOs/AS1372 Revision 1. ...
