The ZXCL series are very small low dropout regulators designed for use in low power and severely space limited applications. The devices operate with a low dropout voltage, typically of only 85mV at 50mA load. Supply current is minimised with a ground pin current of only 50µA at full 150mA load. Logic control allows the devices to be shut down, consuming typically less than 10nA. These features make the device ideal for battery powered applications where power economy is critical.

ZXCT1011 is a high side current sense monitor. Using this type of device eliminates the need to disrupt the ground plane when sensing a load current. The ZXCT1011 takes the voltage developed across a current shunt resistor and translates it into a proportional output current. A user defined output resistor scales the output current into a ground referenced voltage. A current reference resistor, external to the IC, results in an improved temperature coefficient compared to the ZXCT1009. The wide input voltage range of 2.5V down to as low as 2.5V make it suitable for a range of applications. With a minimum operating current of just 4uA, combined with its SOT23-5 package make it suitable for portable battery equipment too.
