B4252CK5-4.5 datasheet

 

Description :

The B4252 series are a group of positive output voltage, five-pin regulators, which provide a high current even when the input/output voltage differential is small. Low power consumption and high accuracy is achieved though CMOS and programmable fuse technologies. Output voltage : 2.0V to 6.0V in 0.1V increments. The B4252 consists of a high-precision voltage reference, an error correction circuit, and a current limited output driver. Key features include a Shutdown Pin that reduces supply current to 0.5µA max and a 470pF Bypass input to ground reduces noise present on the internal reference, which in turn significantly reduce output noise. If output noise is not concern, this input maybe left unconnected. Larger capacitor values cap be used, but results in longer time period to rated output voltage when power initially applied.

Features

1. Maximum Output Current : 250 mA.
2. Highly Accurate Output Voltage +/- 1.4%
3. Only 19μA Power Consumption MAX
4. Shutdown Supply Current 1μA
5. Ground Current of Less than 5μA

Applications

1. Battery Powered Equipment
2. Notebook PC, Palmtops, PDA
3. Portable Cameras and Video Recorders
4. Reference Voltage Sources
5. Cellular / GSM / PCS Phones
