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 B4251 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 0.5 µA 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. The ON/OFF pin enables the output to be turned off, resulting in reduced power consumption. Provided in SOT-25 (150mW) packages minimizes the usage of board real state. Features • Maximum Output Current: 250 mA. • Highly Accurate Output Voltage +/- 1.4% • Only 19 µA Power Consumption MAX • Shutdown Supply Current 1 µA • Ground Current of Less than 5 µA • Very Low Dropout 0.12V at 100mA 0.23V at 250mA • Shutdown Mode for Power Savings • With ON/OFF & BYPASS Features • Offered in SOT-89 & SOT-25 Packages • PIN-to-PIN S-818 Applications • Battery Powered Equipment • Notebook PC, Palmtops, PDA • Portable Cameras and Video Recorders • Reference Voltage Sources • Cellular / GSM / PCS Phones Bay Linear Inspire the Linear Power SOT-89 (R) Top View On/Off Vin Vss 3 2 1 4 5 Vout NC SOT-25 (K5) Top View ON/OFF Vin GND 3 2 1 4 5 Vout Bypass |
