DESCRIPTION  
The UTC L1923 is a low supply current, low dropout linear regulator.  
3
It is operating at 2.5V - 5.5V. The supply current is as low as 55μA in  
the no–load condition. In the shutdown mode, the maximum supply  
current is less than 1μA.  
2
1
A built-in over-temperature protection circuit is designed to protect  
the device from being damaged by thermal overload. The over-current  
protection limit is set at 800mA (TYP.)  
The UTC L1923 can be operated on the following two modes. When  
the SET pin is connected to ground, the output of L1923 is a pre-set  
value and the external components are not needed to decide the  
output voltage. When an output other than the preset value is needed,  
two external resistors should be used as voltage dividers and then the  
output voltage is decided by the resistor ratio.  
SOT-25  
The UTC L1923 is generally used in notebook computers, cellular  
phones, PDAs, digital still camera and video recorders and other  
hand-held devices.
