Overview

The HE2240 ultra-low quiescent current regulator features low dropout voltage and low current in the standby mode. With less than 1.4μA quiescent current at no load, the HE2240 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 HE2240 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 device is available in fixed output voltages of 3.0, 3.3, 3.6, 4.0 and 5.0V. The device features integrated short-circuit and thermal shutdown protection. Although designed primarily as fixed voltage regulators, the device can be used with external components to obtain variable voltages.
