description the fc7630 is a multi-o utput positive voltage regu l ator designed to provide fixed precision outp ut voltages of 5.1v, 8v at current up to 0.5a and 12v at current up to 1a with external pnp transistor. an internal reset circuit generates a reset pulse when the output 1 decrease below the r egulated value. output2 & 3 can be disabled by ttl input. protection features include over voltage protection, short circuit protection and thermal shutdown. features ? output currents up to 0.5a (output1 & 2) ? output current up to 1a with external transistor (output3) ? fixed precision output 1 voltage 5.1v 2 % ? fixed precision output 2 voltage 8v 2 % ? control signal generator for output 3 voltage (12v 2 %) ? reset facility for output voltage1 ? output 2,3 with disable by ttl input ? current limit protection at each output ? thermal shut down internal block diagram 10-sip h / s t a = 0 ... +125 c fc7630 sp fixed- multi-output regulators 1 2 4 6 8 9 3 7 10 5 v1 in v2 in v1 in v2 in output 1 output 2 output 2,3 1.4v disable gnd output 3 control 10k vsys a614 "y" cd 100nf reset del.cap - + scp - + 10a sw bandgap reference - + 50mv thermal shut down + - ovp + - scp + - ovp scp 2.5v
