NCP5504: Linear Voltage Regulator, LDO, Dual Output, 250 mA

Product Description
The NCP5504 is a dual output low dropout (LDO) linear voltage regulator with a +/-2.0% accuracy over the operating temperature range. It features a fixed output voltage of 3.3 V (contact factory for other fixed output voltage options) and an adjustable output that ranges from 1.25 V to 5.0 V. It is available in a 5 pin DPAK Pb-free package.

The NCP5504 LDO linear voltage regulator provides low noise operation without a bypass capacitor for the fixed output. This device has ripple rejection of 75 dB and a dropout voltage of 250 mV at 250 mA. The NCP5504 is suitable for post-regulation and power sensitive battery-operated applications.
