description 7632 is a multi-output positive voltage regulator de- signed 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 regulated 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 t ransistor (output3) fixed precision output 1 voltage 3.3v 2% fixed precision output 2 voltage 8v 2% (gm7632) 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 typical applica tion 7632 1 2 3 4 5 6 7 8 9 10 v1 in v2 in active disable "h" cd gnd reset 10k vsys c o n to rl output 2 output 1 output3 0.5amp the f f 0.5amp fixed multi-output positive voltage regulator
