DESCRIPTION
4 5 2 3 The UTC It is operating at 2.5V - 5.5V. In the shutdown mode, the maximum supply current is less than 1μA. 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. The UTC L1923 is generally used in notebook computers, cellular phones, PDAs, digital still camera and video recorders and other hand-held devices. 1 SOT-25 FEATURES
