B4500

Bay Linear Inspire the Linear Power 500 mA Low Dropout Voltage Regulators B4500 Preliminary Information Description The B4500 series are a group of positive output voltage, three-pin regulators, that provide a high current even when the input/output voltage differential is small. Very low power consumption, only 2µA typ., and high accuracy is achieved though CMOS construction and programmable fuse technologies. Output voltage: 2.0V to 6.0V in 0.1V increments. The B4500 consists of a high-precision voltage reference, an error correction circuit, and a current limited output driver. Available in SOT223 (500mW) and SOT-89 (300mW) packages minimizing the usage of board real state. Features Maximum Output Current: 500 mA. Highly accurate: Output voltage +/- 2%. Only 2µA power Consumption. Very Low Dropout: 0.11V @ 100mA 0.3V @ 300mA 0.5V @ 450mA Offered in SOT-89 & SOT-223 Packages Applications Battery Powered Equipment Notebook PC, Palmtops, PDA Portable Cameras and Video Recorders Reference Voltage Sources Pin Connection Ordering Information Package SOT-223 SOT-89 Part No. B4500CN-X.X B4500CR-X.X SOT-89 (R) X.X = Fixed Output Voltages from 2.0V to 6.0V SOT-223 (N) Vin Vin 2 2 1 Vss 2 3 1 Vss 2 3 Vin Vout Vin Vout Top View Top View Bay Linear, Inc 2478 Armstrong Street, Livermore, CA 94550 Tel: (925) 606-5950, Fax: (925) 940-9556 www.baylinear.com B4500 Absolute Maximum Ratings Parameter Input Voltage Output Current Output Voltage Contin...
