L1188
Preliminary
800mA CMOS LDO
„ DESCRIPTION
As UTC LDO, the features of the UTC L1188 include low
quiescent current and very low dropout voltage.
In order prevent form the bad operating conditions, there are
internal thermal shutdown and current fold-back. For stably
operation, the UTC L1188 should be connected to an output
capacitance of 2.2μF or larger.
The UTC L1188 can be an ideal for battery applications, such as
portable electronics, wireless devices, cordless phones, PC
peripherals and battery powered widgets.
„ FEATURES
* Extra Low Dropout Voltage
* Output Current: 800mA (Guaranteed)
* Output Voltage Accuracy:±1.5%
* Quiescent Current: 30μA
* Internal Over-Temperature Shutdown
* With Current limiting
* Internal Short Circuit Current Fold-Back
* Pre-set Output Voltages In Factory
* Very Low Temperature Coefficient
