8 / 9 page  ZLDO330 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 µA. 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).
