Bay Linear Inspire the Linear Power B4151 150 mA CMOS Low Dropout LDO ON/OFF Description Features The B4151 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 B4151 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. With good transient responses, output remains stable even during load changes. • • • • 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. Maximum output current: 150 mA. Highly accurate: Output voltage +/- 2%(1%) Shutdown Supply Current 1µ µA Ground Current of Less than 20µ µA CMOS low power consumption. 0.20V at 160mA 0.38V at 80mA Small input/output differential: Shut Down Mode for Power Savings Improve pin-to-pin XC62GR-XX Pin-to-Pin Low Power to Bipolar LDO’s Applications • • • • • Battery Powered Equipment Notebook PC, Palmtops, PDA Portable Cameras and Video Recorders Reference Voltage Sources Cellular / GSM / PCS Phones Ordering Information Pin Connection Package Part No. SOT-25 B4151CK5 -X.X X.X = Fixed Output Voltages from 2.0V to 6.0V SOT-25 (K5) NC V out 5 1 4 2 3 VSS VIN ON/OFF Top View Bay Linear, Inc 2478 Armstrong Street, Livermore, CA 94550 Tel: (925) 606-5950, Fax: (925) 940-9556 www.baylinear.com B4151 Absolute Maximum Ratings Parameter Input Voltage Output Current Output Voltage CE Output Voltage Continual Total Power Dissipation Symbol VIN IOUT Vout VOUT SOT-25 SOT-89 Operating Ambient Temperature Storage Temperature Pd TOPR TSTG Ratings 12 500 VSS -0.3 to VIN 0.3 VSS -0.3 to VIN 0.3 300 500 -30 to 80 -40 to 125 Units V mA V V mW °C °C Electrical Characteristics (Ta = 25°°C, VIN = VOUT + 0.5V; unless otherwise noted) Parameter Output Voltage Accuracy ∆VOUT/∆VIN-VOUT Line Regulation Load Regulation Conditions IO = 1mA IO = 0 to 40mA IO= 40mA, (VOUT + 0.1V)<VIN<10V VIN=Vout+1V 1mA < IO < 80mA COUT = 1µF Maximum Output Current Current Limit CE input voltage High CE input voltage Low CE input voltage High CE input voltage Low ∆Vout/∆Topr ..
