Because in such cases, the power dissipation consumed by BL8071G is very large. BL8071G series uses SOT-223 package type and its thermal resistance is about 20°C/W. And the copper area of application board can affect the total thermal resistance. If copper area is 5cm*5cm (two sides), the resistance is about 30°C/W. So the total thermal resistance is about 20°C/W + 30°C/W. In this case, the power dissipation should be limited less than 1.2W. We can decrease total thermal resistance by increasing copper area in application board. When there is no good heat dissipation copper are in PCB, the total thermal resistance will be as high as 120°C/W, then the power dissipation of BL8071G could allow on itself is less than 1W. And furthermore, BL8071G will work at junction temperature higher than 125°C under such condition and no lifetime is guaranteed. CURRENT LIMIT MODE Current Limit module can keep chip and power system away from danger when the load current is higher than the current limit threshold. When VOUT decrease the Short Circuit Current will fold back to a small value. SHORT CIRCUIT PROTECTION When VOUT short to GND, the short circuit protection will be triggered and clamp the output current to approximately 300mA. This feature protects the regulator from over current and damage due to overheating. www.belling.com.cn 4 Your final power solution BL8071G TYPICAL PERFORMANCE CHARACTERISTICS Line Regulation Load Regulation (Vout=3.3V) (Vout=3.3V) 4.0 3.5 3.5 3.0 2.5 Vout(V) Vout(V) 3.0 2.0 2.5 2.0 1.5 1.0 0.5 0.0 0 Iout=10mA Iout=100mA Iout=1000mA 1.5 Vdd=4.0V Vdd=4.3V Vdd=5.0V 1.0 0.5 1 2 1.5 3 4 Vdd (V) Iout(A) Dropout Voltage 120 600 100 500 80 Iq (uA)) Vdropout(mV) 6 IQ (Vout=3.3V) (Vout=3.3V) 700 5 400 300 60 40 200 Ta=25℃ Ta=-40℃ Ta=85℃ 100 0 0 500 1000 Ta=25℃ Ta=-40℃ Ta=85℃ 20 0 1500 Iout(mA) 0 1 2 3 Vdd (V) 4 5 Vout vs. Temp Load Transient Response (Vdd=5V, Iout=10mA) (Vdd=5V, Vout=3.3V, Iout=10mA-1A, Trise=10uS) 4.0 6 3.5 Vout(V) 3.0 Vout_ripple, 100mV/div 2.5 2.0 Iout, 500mA/div 1.5 1.0 0.5 Vout=3.3V 0.0 -40 0 40 80 120 160 200 CH1: Vout_ripple, CH4: Iout Ta(℃) www.belling.com.cn 5 Your final power solution BL8071G PACKAGE OUTLINE Package SOT-223 Devices per reel 2500Pcs Package dimension: C C COMMON DIMENSIONS L1 (UNITS OF MEASURE=MILLIMETER) E1(BTM) E2(TOP) L1 E θ θ θ R R D e e1 e L2 0.10 A3 D2 D(TOP) L D A1 0.08 D1(BTM) b2 b3 SECTION D-D θ θ MIN 0.02 1.50 0.80 0.67 0.66 2.96 2.95 0.30 0.29 6.48 6.55 6.80 3.40 3.33 0.80 0.10 0.10 0° 10° NOM 1.60 0.90 0.71 3.00 0.30 6.53 6.60 3.50 3.43 2.30BSC 4.60BSC 1.00 1.75REF 0.25BSC 12° MAX 1.80 0.10 1.70 1.00 0.80 0.76 3.09 3.05 0.35 0.31 6.58 6.65 7.05 7.20 3.60 3.53 1.20 8° 14° NOTES: ALL DIMENSIONS REFER TO JEDEC STANDARD TO261-AA c1 c θ A2 A b b1 c1 c θ SYMBOL A A1 A2 A3 b b1 b2 b3 c c1 D D1 D2 E E1 E2 e e1 L L1 L2 R R1 SECTION C-C Unit: mm www.belling.com.cn 6 Your final power solution BL8071G Package TO-252 Devices per reel 2500Pcs Package dimension: Unit: mm www.belling.com.cn 7 Your final power solution
