B4250

Bay Bay Linear Inspire Inspire the Linear Power 250 mA CMOS Low Dropout LDO B4250 Description The B4250 series are a group of positive output voltage, three-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 B4250 consists of a high-precision voltage reference, an error correction circuit, and a current limited output driver. Available in SOT-23 (150mW) and SOT-89 (500mW) packages minimizing the usage of board real state. Features • • • • • Maximum output current: 250 mA. Highly accurate: Output voltage +/- 2%. (1%) CMOS low power consumption. Small input/output differential: 0.38V at 160mA (Vout=3.3V) 0.12V at 100mA (Vout=5V) Pin-to-Pin Improve XC62FP/XC6201 Applications • • • • Battery Powered Equipment Notebook PC, Palmtops, PDA Portable Cameras and Video Recorders Reference Voltage Sources Pin Connection Ordering Information -40°C to +125°C Package SOT-23 Part No. B4250CK3 -X.X B4250CR-X.X SOT-23-3 (K3) SOT-89 SOT-89 (R) Vin 2 Vin 3 1 2 X.X = Fixed Output Voltages from 2.0V to 6.0V 1 Vss 2 3 Vss Vout Top View Vin Vout Top View Bay Linear, Inc 2418 Armstrong Street, Livermore, CA 94550 Tel: (925) 606-5950, Fax: (925) 940-9556 www.baylinear.com B4250 Absolute Maximum Ratings Parameter Input Voltage Output Current Output Voltage Continual Total Power Dissipation Operating Ambient Temperature Storage Temperature Symbol VIN IOUT VOUT SOT-23 SOT-89 Pd TOPR TSTG Ratings 12 500 VSS -0.3 to VIN 0.3 150 500 -30 to 80 -40 to 125 Units V mA V mW °C °C Electrical Characteristics (Ta = 25°C, VIN = VOUT + 1V; unless otherwise noted) Parameter Output Voltage Line Regulation ∆VOUT/∆VIN-VOUT Load Regulation Current Consumption Dropout Voltage 3.3V 5.0V 3.3V 5.0V 3.3V 5.0V 3.3V 5.0V 3.3V 5.0V Conditions IO = 40mA, VIN = 4.3V IO = 40mA, VIN = 6.0V IO = 40mA, 4.3V
