L11810
Preliminary
1A CMOS LOW DROPOUT
VOLTAGE
„ DESCRIPTION
As UTC LDO, the features of the UTC L11810 include low
quiescent current and very low dropout voltage.
In order to prevent from the bad operating conditions, there are
internal thermal shutdown and current fold-back. For stably
operation, the UTC L11810 should be connected to an output
capacitance of 2.2μF or larger.
The UTC L11810 is ideal for battery applications, such as
portable electronics, wireless devices, cordless phones, PC
peripherals and battery powered widgets.
„ FEATURES
