DESCRIPTION

The UR60XX ultra-low quiescent current regulator features low

dropout voltage and low current in the standby mode. With less than

5μA quiescent current at no load, the UR60XX 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 UR60XX 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 UR60XX has a 65-V maximum operating voltage limit, a

-40°C to 125°C operating temperature range, and ±2% output

voltage tolerance.
