Datasheet TSM1012 (STMicroelectronics) - 5

TSM1012 Electrical characteristics Table 5. Electrical characteristics (continued) Symbol Parameter Test condition Min. Typ. Max. Unit
Reference input voltage deviation over the VCC Iload = 1 mA RegLine 20 mV range. Reference input voltage deviation over the VCC = 18 V, RegLoad 10 mV output current. 0 < Iload < 2.5 mA 1. Test conditions: pin 2 and 6 connected to GND, pin 4 and 5 connected to 1.25 V, pin 3 connected to 200 mV. 2. The current depends on the difference voltage between the negative and the positive inputs of the amplifier. If the voltage on the minus input is 1 mV higher than the positive amplifier, the sinking current at the output OUT will be increased by Gm x 1 mA. DocID10124 Rev 2 5/14 14 Document Outline Figure 1.
