300mA Low-Dropout Linear Regulators In the shutdown mode, the maximum supply current is less than 1μA. Operating voltage range of the CXSD62421 is from 2.5V to 5.5V

   产品概述 返回TOPZBb嘉泰姆

The CXSD62421 is a low supply current, low dropout linear regulator that comes in a space saving SOT-23-5 package. The supply current at no-load is 90μA. In the shutdown mode, the maximum supply current is less than 1μA. Operating voltage range of the CXSD62421 is from 2.5V to 5.5V. The over-current protection limit is set at 550mA typical. An over-temperature protection circuit is built-in in the CXSD62421 to prevent thermal overload. These power saving features make the CXSD62421 ideal for use in the battery-powered applications such as notebook computers, cellular phones, and PDA’s. The CXSD62421 has two modes of operation. When the SET pin is connected to ground, its output is a pre-set value: 1.5V~4.7V (interval =100mV), 2.84V, 3.15V, and 4.75V. There is no external component needed to decide the output voltage. When an output other than the preset value is needed, two external resistors should be used as a voltage divider. The output voltage is then decided by the resistor ratio. The CXSD62421 comes in a space saving SOT-23-5 package.
