description the fc7632 is a multi-o utput positive voltage regu l ator designed to provide fixed precision output voltages of 3.3v, 8v at current up to 0.5a and 5.1v 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 3.3v 2 % ? fixed precision output 2 voltage 8v 2 % ? control signal generator for output 3 voltage (5.1v 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 2 bandgap reference 1 vin1 vin2 0vp vin1 + - 2.5v scp 9 50mv thermal shut down 0vp - + scp 8 output 1 output 2 1.4v output 2,3 + - disable 4 5 gnd scp sw 10 a - + 3 6 7 10 del.cap reset output 3 cd 100nf vsys 10k control a614 - + vin2 fc7632 sp fixed- multi-output regulators
