Technical content

3-TERMINAL 1A POSITIVE ADJUSTABLE REGULATOR The FR317P/D/DD/T is adjustable 3-terminal positive voltage regulator capable of supplying in excess of 1.5A over a 1.2V to 37V output range. This is exceptionally easy to use and require only two external resistors to set the output voltage. Further, it employ internal current limiting, thermal shutdown and safe area compensation.

FEATURES

Adjustable output between 1.2V and 37V Guaranteed 1.5A output current Line regulation typically 0.01%/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 BLOCK DIAGRAM Protection Circuitry Voltage Reference I 2 I 3 1 I IN V Adj V O 2018. 05. 02 1/5 SEMICONDUCTOR TECHNICAL DATA FR317P/D/DD/T Revision No : 3 TO-252 TO-263 TO-220 DIM MILLIMETERS A B C D E F H J N O 0.8 ± 0.1 2.7 ± 0.2 2.54 ± 0.2 13.5 ± 0.3 3.7 ± 0.2 10.3 ± 0.2 4.5 ± 0.2 2.7 ± 0.2

ELECTRICAL CHARACTERISTICS (Ta=25℃) (V I -V O =5V, I O =0.5A, 0℃≤Tj≤125℃, I =1.5A, P =20W, unless otherwise specified.) Note : Load and line regulation are specified at constant junction temperature. Change in Vo due to heating effects must be taken into account separately. Pulse testing with low duty is used.

TYPICAL APPLICATION (PROGRAMMABLE REGULATOR) V IN V O Adj C Adj Adj I 2 R i O 2 R C 1 R 2 R OUT V = 1.25V (1 + ) + I R 1 μ F 0.1 μ F V IN 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 1μF to 100μF of aluminum or tantalum electrolytic are commonly used to provide improved output impedance and rejection of transients. Since I Adj is controlled to less then 100μA , the error associated with this term is negligible in most applications. 2018. 05. 02 3/5 FR317P/D/DD/T Revision No : 3 FR317
