SEMICONDUCTOR KIA317F/FP/PI/S TECHNICAL DATA BIPOLAR LINEAR INTEGRATED CIRCUIT 3-TERMINAL 1A POSITIVE ADJUSTABLE REGULATOR The KIA317F/FP/PI/S is adjustable 3-terminal positive voltage regulator capable of supplying in excess of 1.5A over a 1.25V to 37V output range. This is exceptionally easy to use and require only two external resistors to set the output voltage. Further, both line and load regulation are better than standard fixed regulators. FEATURES ・Adjustable output between 1.25V and 37V ・Guaranteed 1.5A output current ・Line regulation typically 0.001%/V ・Load regulation typically 0.1% ・80dB ripple rejection (with Cadj) ・Internal thermal overload protection ・Internal short-circuit current limiting ・Output transistor safe-area compensation MAXIMUM RATINGS (Ta=25℃) CHARACTERISTIC SYMBOL RATING UNIT Input-Output Voltage Differential VIN 40 V Output Current IOUT 1.5 A F Power Dissipation FP (No Heatsink) PI 1.3 PD S (Note) 2.0 W 2.0 1.0 Operating Temperature Topr -30～85 ℃ Storage Temperature Tstg -65～150 ℃ Tlead 230 ℃ Lead Temperature Note) : Package Mounted on FR-4 PCB 36×18×1.5㎜. mounting pad for the GND Lead min. 6㎠.

TYPICAL APPLICATION (PROGRAMMABLE REGULATOR) V IN V IN VO Adj I Adj R1 Ci 0.1µF V OUT = 1.25V (1 + R2 ) + I Adj R 2 R1 CO 1µF R2 Ci is required when regulator is located an appreciable distance from power supply filter. Co is not needed for stability, however, in the range of 1㎌ to 100㎌ of aluminum or tantalum electrolytic are commonly used to provide improved output impedance and rejection of transients. Since IAdj is controlled to less then 100㎂, the error associated with this term is negligible in most applications. 2005. 6. 24 Revision No : 4 2/6 KIA317F/FP/PI/S Current Limit 3 0 OUTPUT CURRENT (A) 0.2 IL = 0.5A -0.2 IL = 1.5A -0.4 -0.6 -0.8 -1.0 -75 VIN =15V VOUT =10V -50 -25 25 50 75 100 125 0 35 0 25 50 75 100 125 150 40 3.0 VOUT =100mV 2.5 IL = 1.5A IL = 1A 2.0 IL = 500mA 1.5 IL = 200mA IL = 20mA 1.0 -75 -50 -25 0 25 50 75 100 TEMPERATURE ( C) TEMPERATURE ( C) Temperature Stability Minimum Operating Current 1.260 125 150 4.5 QUIESCENT CURRENT (mA) REFERENCE VOLTAGE (V) 30 Dropout Voltage 40 1.250 1.240 1.230 4.0 3.5 -25 0 25 50 75 100 125 150 Revision No : 4 T j =-55 C 3.0 2.5 T j =150 C 2.0 1.5 1.0 T j =25 C 0.5 0 -50 TEMPERATURE ( C) 2005. 6. 24 20 Adjustment Current 45 1.220 -75 10 INPUT-OUTPUT DIFFERENTIAL (V) 50 -25 Tj = 25 C TEMPERATURE ( C) 55 -50 Tj = -55 C Tj = 150 C 1 150 60 -75 2 0 0 INPUT-OUTPUT DIFFERENTIAL (V) ADJUSTMENT CURRENT (µA) OUTPUT VOLTAGE DEVIATION (%) Load Regulation 0 10 20 30 40 INPUT-OUTPUT DIFFERENTIAL (V) 3/6 KIA317F/FP/PI/S Ripple Rejection Ripple Rejection 100 100 RIPPLE REJECTION (dB) RIPPLE REJECTION (dB) CADJ =10µF 80 CADJ =0 60 40 20 VIN - VOUT = 5V IL=500mA, f = 120Hz Tj=25 C 0 0 5 10 20 25 30 1K 10K Ripple Rejection Output Impedance 100K 1M 100K 1M 1 10 OUTPUT IMPEDANCE (Ω) RIPPLE REJECTION (dB) 100 0 CADJ =0 40 20 VIN = 15V, VOUT = 10V f = 120Hz, Tj=25 C VIN = 15V, VOUT = 10V IL=500mA, Tj=25 C 0 10 CADJ =10µF -1 10 CADJ =0 -2 10 -3 0 10 0.01 0.1 1 10 10K Line Transient Response Line Transient Response CL=1µF; CL=0; CADJ =10µF CADJ =0 VOUT = 10V IL=50mA Tj=25 C 1.0 0.5 0 0 1K FREQUENCY (Hz) 1.0 0 100 OUTPUT CURRENT (A) 1.5 0.5 10 10 20 TIME (µs) Revision No : 4 30 40 LOAD CURRENT (A) OUTPUT VOLTAGE DEVIATION (V) INPUT VOLTAGE OUTPUT VOLTAGE CHANGE (V) DEVIATION (V) 20 FREQUENCY (Hz) 60 2005. 6. 24 40 OUTPUT VOLTAGE (V) CADJ =10µF -1.5 CADJ =0 60 35 80 -1.0 80 0 15 100 -0.5 VIN = 15V, VOUT = 10V IL=500mA, Tj=25 C CADJ =10µF 3 2 CL=0; 1 0 CL=1µF; -1 CADJ =0 CADJ =10µF VIN = 15V VOUT = 10V INL=50mA Tj=25 C -2 -3 1.5 1.0 0.5 0 0 10 20 30 40 TIME (µs) 4/6 KIA317F/FP/PI/S Power Dissipation-3 (D2PAK) Power Dissipation-2 (DPAK) 40 12 9 6 3 0 50 0 100 POWER DISSIPATION PD (W) 30 25 20 15 10 5 0 -25 150 0 25 50 75 100 125 AMBIENT TEMPERATURE Ta ( C) Power Dissipation-1 (TO-220IS) Power Dissipation-4 (SOT-223) 12 THERMAL RESISTANCE J-C J-A C/W 6.0 62.5 20 16 12 8 4 0 -25 THERMAL RESISTANCE J-A J-C C/W 62.5 3.6 35 AMBIENT TEMPERATURE Ta ( C) 24 0 50 100 AMBIENT TEMPERATURE Ta ( C) 2005. 6. 24 POWER DISSIPATION PD (W) THERMAL RESISTANCE J-A J-C C/W 9.62 96.2 POWER DISSIPATION PD (W) POWER DISSIPATION PD (W) 15 Revision No : 4 150 150 THERMAL RESISTANCE J-A J-C C/W 15 125 10 8 6 4 2 0 -25 0 50 100 150 AMBIENT TEMPERATURE Ta ( C) 5/6 KIA317F/FP/PI/S A C J M O E K Q P F L F 2 3 MILLIMETERS _ 0.2 9.8 + _ 0.2 8.8 + 8.0 _ 0.3 15 + _ 0.2 5.0 + _ 0.1 2.54 + _ 0.1 0.8 + _ 0.2 4.0 + _ 0.13 1.27 + 6.7 _ 0.15 0.5 + 0~0.25 _ 0.1 1.27 + _ 0.3 2.3 + 7.85 0~0.15 DIM A B B MILLIMETERS _ 0.2 6.60 + _ 0.2 6.10 + _ 0.2 5.0 + _ 0.2 1.10 + _ 0.2 2.70 + _ 0.1 2.30 + 1.00 MAX _ 0.2 2.30 + _ 0.1 0.5 + _ 0.20 2.00 + _ 0.10 0.50 + _ 0.10 0.91+ _ 0.1 0.90 + _ 0.10 1.00 + 0.95 MAX C D E F D DIM A B C D E F H I J K L M O P Q N M R E B D J H 1 I A I G O F 1 3 2 G L I J P K L C M N O Q R K Q 1.
