General Description
The ZC2205 ultra-low quiescent current regulator features low dropout voltage and low current in the standby mode. With less than 1.5μA quiescent current at no load, the ZC 2205 is ide ally 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 ZC2205 retains all o f the features that are common to low dropout regulators including a low dropout PMOS pass devi ce, short circuit protection, and thermal shutdown.
The ZC2205 has a 24-V maximum operating voltage limit, a -40°C to 125°C operating temperat ure range, and ±2% output voltage Tolerance
