APPLICATIONS
5). Logic Controlled Power Supply
Fig.4 shows all that is necessary to allow a
microprocessor to control a power supply
based on the ZLDO330. The Shutdown Control
pin (pin 2), is a logic compatible input that
disables the regulator when a voltage in
excess of 1.5V is applied. The current required
to drive this input is less than 10uA. When the
regulator is shutdown in this way, the
quiescent current of the ZLDO330 falls to
around 11 μ A. This makes the regulator
suitable for a wide range of battery powered
applications where intermittent operation
occurs. The shutdown control pin should not
be taken to a voltage higher than Vin if low
quiescent supply current is important. The
shutdown control is a high impedance input
and so if not required, should be wired to the
ground pin (pin 7).
