产品概述 返回TOP
The CXSD62459 is a dual, low supply current, low dropout linear regulator that comes in a space saving TDFN2X2-8 package. The supply current at no-load is 100μA. In the shutdown mode, the maximum supply current is less than 1μA. The over-current protection limit is set at 430mA typical. An over-temperature protection circuit is built-in in the CXSD62459 to prevent thermal overload. These power saving features make the CXSD62459 ideal for use in the battery-powered applications such as notebook computers, cellular phones, and PDA’s. The GCXSD62459have two logic inputs that select one of nine preset output-voltage combinations, eliminating external 1% resistors. The GCXSD62459configures output voltages at VOUT1 and VOUT2 based on the state of P1 and P2 at power-on. Subsequent changes to P1 and P2 do not change the output voltages unless the supply power is cycled, or all EN inputs are simultaneously driven low to shut down the device. These devices feature a shutdown function and are offered in active low with auto discharge. The CXSD62459comes in a space saving TDFN2X2-8 package.
