KIA317S

SEMICONDUCTOR TECHNICAL DATA 3-TERMINAL 1A POSITIVE ADJUSTABLE REGULATOR KIA317F/FP/PI/S BIPOLAR LINEAR INTEGRATED CIRCUIT 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 Input-Output Voltage Differential Output Current F Power Dissipation (No Heatsink) FP PI S (Note) Operating Temperature Storage Temperature Lead Temperature mounting pad for the GND Lead min. 6㎠.

TYPICAL APPLICATION (PROGRAMMABLE REGULATOR) V IN V IN Adj I Adj Ci 0.1µF R2 VO R1 CO 1µF V OUT = 1.25V (1 + R2 ) + I Adj R 2 R1 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 Load Regulation OUTPUT VOLTAGE DEVIATION (%) 0.2 0 -0.2 IL = 1.5A IL = 0.5A Current Limit 3 OUTPUT CURRENT (A) 2 -0.4 -0.6 -0.8 -1.0 -75 1 Tj = 150 C Tj = -55 C VIN =15V VOUT =10V Tj = 25 C 0 0 25 50 75 100 125 150 -50 -25 0 10 20 30 40 TEMPERATURE ( C) INPUT-OUTPUT DIFFERENTIAL (V) Adjustment Current ADJUSTMENT CURRENT (µA) 60 55 50 45 40 35 -75 -50 -25 0 25 50 75 100 125 150 Dropout Voltage INPUT-OUTPUT DIFFERENTIAL (V) 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 75 100 125 150 TEMPERATURE ( C) TEMPERATURE ( C) Temperature Stability 1.260 4.5 Minimum Operating Current QUIESCENT CURRENT (mA) REFERENCE VOLTAGE (V) 4.0 3.5 3.0 2.5 2.0 1.5 1.0 0.5 0 0 10 20 30 40 T j =25 C T j =150 C T j =-55 C 1.250 1.240 1.230 1.220 -75 -50 -25 0 25 50 75 100 125 150 TEMPERATURE ( C) INPUT-OUTPUT DIFFERENTIAL (V) 2005. 6. 24 Revision No : 4 3/6 KIA317F/FP/PI/S Ripple Rejection 100 100 CADJ =10µF Ripple Rejection VIN = 15V, VOUT = 10V IL=500mA, Tj=25 C RIPPLE REJECTION (dB) 80 CADJ =0 RIPPLE REJECTION (dB) 80 60 CADJ =10µF CADJ =0 60 40 40 20 0 20 0 0 VIN - VOUT = 5V IL=500mA, f = 120Hz Tj=25 C 5 10 15 20 25 30 35 0 100 1K 10K 100K 1M OUTPUT VOLTAGE (V) FREQUENCY (Hz) Ripple Rejection 100 80 60 40 20 VIN = 15V, VOUT = 10V f = 120Hz, Tj=25 C Output Impedance 10 1 VIN = 15V, VOUT = 10V IL=500mA, Tj=25 C OUTPUT IMPEDANCE (Ω) RIPPLE REJECTION (dB) CADJ =10µF CADJ =0 10 0 CADJ =10µF 10 -1 10 -2 CADJ =0 0 0.01 0.1 1 10 10 -3 10 100 1K 10K 100K 1M OUTPUT CURRENT (A) FREQUENCY (Hz) INPUT VOLTAGE OUTPUT VOLTAGE CHANGE (V) DEVIATION (V) LOAD CURRENT (A) OUTPUT VOLTAGE DEVIATION (V) Line Transient Response 1.5 1.0 0.5 0 -0.5 -1.0 -1.5 1.0 0.5 0 0 10 20 30 40 CL=0; CL=1µF; CADJ =0 CADJ =10µF Line Transient Response 3 2 1 0 -1 -2 -3 1.5 1.0 0.5 0 0 10 20 30 40 CL=0; CL=1µF; CADJ =0 CADJ =10µF VIN = 15V VOUT = 10V INL=50mA Tj=25 C VOUT = 10V IL=50mA Tj=25 C TIME (µs) TIME (µs) 2005. 6. 24 Revision No : 4 4/6 KIA317F/FP/PI/S Power Dissipation-2 (DPAK) 15 40 Power Dissipation-3 (D2PAK) POWER DISSIPATION PD (W) THERMAL RESISTANCE J-A J-C C/W 62.5 3.6 POWER DISSIPATION PD (W) 12 9 6 3 0 0 50 THERMAL RESISTANCE J-A J-C C/W 9.62 96.2 35 30 25 20 15 10 5 0 -25 0 25 50 75 100 150 100 125 150 AMBIENT TEMPERATURE Ta ( C) AMBIENT TEMPERATURE Ta ( C) Power Dissipation-1 (TO-220IS) 24 Power Dissipation-4 (SOT-223) 12 POWER DISSIPATION PD (W) 20 16 12 8 4 0 -25 POWER DISSIPATION PD (W) THERMAL RESISTANCE J-C J-A C/W 6.0 62.5 10 8 6 4 2 0 -25 THERMAL RESISTANCE J-A J-C C/W 15 125 0 50 100 150 0 50 100 150 AMBIENT TEMPERATURE Ta ( C) AMBIENT TEMPERATURE Ta ( C) 2005. 6. 24 Revision No : 4 5/6 KIA317F/FP/PI/S A C D I J A I J H F 1 2 F 3 P L DIM A B C D E F H I J K L M O P Q MILLIMETERS _ 6.60 + 0.2 _ 6.10 + 0.2 _ 5.0 + 0.2 _ 1.10 + 0.2 _ 2.70 + 0.2 _ 2.30 + 0.1 1.00 MAX _ 2.30 + 0.2 _ 0.5 + 0.1 _ 2.00 + 0.20 _ 0.50 + 0.10 _ 0.91+ 0.10 _ 0.90 + 0.1 _ 1.00 + 0.10 0.95 MAX DIM A B B N R E G F M O C D E F G I J K L M N O KQ Q R D K 1 2 3 P E L C MILLIMETERS _ 9.8 + 0.2 _ 8.8 + 0.2 8.0 _ 15 + 0.3 _ 5.0 + 0.2 _ 2.54 + 0.1 _ 0.8 + 0.1 _ 4.0 + 0.2 _ 1.27 + 0.13 6.7 _ 0.5 + 0.15 0~0.25 _ 1.27 + 0.1 _ 2.3 + 0.3 7.85 0~0.15 B M Q 1.
