The SSP7955 is ultra-low quiescent current regulator features low dropout voltage and low current in the standby mode. With less than 2.4μA quiescent current at no load, the SSP7955 is ideally suited for standby micro-control-unit systems, especially for always-on applications like E-meters, fire alarms, smoke detectors and other battery-operated systems. The SSP7955 retains all of the features that are common to low dropout regulators including a low dropout PMOS pass device, short circuit protection, and thermal shutdown. The SSP7955 has 50V maximum operating voltage limit, and -40°C to 85°C operating temperature range, and ±2% output voltage tolerance over the entire output current, input voltage, and temperature range. The SSP7955 regulators are available in standard SOT23-3, SOT89 and SOT223 packages. SOT23-3 SOT89 SOT223
