GENERAL DESCRIPTION
The AMS112 series consists of positive fixed voltage regulators featuring an internal electronic switch controlled by TTL or
CMOS logic levels. When the Control pin is pulled to a logic high level, the device is in the ON state. If the control function
is not used, the control terminal should be connected to a logic high level or V
IN
, therefore allowing the regulator to be ON.
The regulator will be ON when the control terminal voltage is grater than 1.8V. To lower the output noise level to 30
μ
V
rms
,
an external capacitor can be connected to the noise bypass pin. These devices feature very low quiescent current of 1mA when
supplying 30mA loads (180
μ
A at no load). This unique characteristic and the low standby current (typ. 100nA) make the
AMS112 ideal to use for standby power systems. Like other regulators the AMS112 series also includes internal current
limiting and thermal shutdown.
The AMS112 is offered in 3.3V and 5.0V output voltages, and is available in the 5-pin SOT-23 surface mount package.
