A single external resistor adjustment can be used to change both outputs between the limits of ±50 mV and ±42V. These devices are designed for local “on-card” regulation, eliminating distribution problems associated with single- point regulation. To simplify application the regulators require a minimum number of external parts. The device is available in three package types to accommodate various power requirements. The K (TO-66) power package can dissipate up to 3W at TA = +25°C. The D 14-pin dual in-line will dissipate up to 1W and the N 14-pin dual in-line will dissipate up to 625 mW. • Internal thermal shutdown at TJ = +175°C • External balance for ±VOUT unbalancing • 3W power dissipations Block Diagram 65-4194-01 Thermal Shutdown 100µA Current Source 20K 4194 20K 3R R +VS +VOUT GND Comp+ RSET Bal RO Comp– –VOUT –VS Rev. 1.0.0 PRODUCT SPECIFICATION RC4194 PRODUCT SPECIFICATION RC4194 19 2 3 456 7 8 +V +VS +VOUT -V (Case) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 S S NC NC +VOUT GND GND Comp+ Bal R SET R Comp+ SET R Comp- O Bal R O NC NC -V S -VOUT Comp -VOUT 65-4194-03 65-4194-02 Absolute Maximum Ratings (beyond which the device may be damaged)1 Parameter Min Typ Max Units Supply Voltage RC4194 ±35 V RM4194 ±45 V Supply Input to Output Voltage Differential RC4194 ±35 V RM4194 ±45 V Load Current PDIP 100 mA CerDIP 150 mA TO-66 Metal Can 250 mA PDTA < 50°C PDIP 468 mW CerDIP 1042 mW TO-66 Metal Can 2381 mW Operating Temperature (Tj) RC4194 0 70 °C RM4194 -55 125 °C Storage Temperature -65 150 °C Junction Temperature PDIP 125 °C CerDIP 175 °C TO-66 Metal Can 150 °C Lead Soldering Temperature (60 seconds) 300 °C For TA > 50°C Derate at TO-66 Metal Can 23.81 mW/°C PDIP 6.25 mW/°C CerDIP 8.38 mW/°C Note: 1.
