PRODUCT DESCRIPTION
The AS2700/01/02 are a low power positive voltage regulators. The AS2700/01/02 offers 700mA output current with a dropout
voltage of only 0.5V and over temperature dropout is up to 1V. The quiescent current is 10mA at differential output of 5V and output
current of 700mA. A higher quiescent current can exist when the device is in dropout mode (V
IN
-V
OUT
≤
3V).
The regulator will automatically shut down to protect both the internal circuits and the load. This device also features short circuit and
thermal overload protection.
The AS2700/01/02 is offered in 3 and 5 pin TO-220, TO-263 and 3-pin SOT-223 packages compatible with other 5V and 3.3V
regulators, TO-263 and 3-pin SOT-223. The device is offered in standard output voltages of 5V and 3.3V as well as in adjustable
output regulator.
