Manufacturer:松下 Description:The AP1187 keeps a constant 1.25V between the VSENSE pin and the ADJ pin. By placing a resistor R1 across these two pins and connecting the VSENSE and VOUT pin together, a constant current flows through R1, adding to the IADJ current and into the R2 resistor producing a voltage equal to the (1.25/R1)*R2 + IADJ*R2. This voltage is then added to the 1.25V to set the output voltage. This is summarized in the above equation. Since the minimum load current requirement of the AP1187 is 10mA, R1 is typically selected to be a 121Ω resistor so that it automatically satisfies this condition. Notice that since the IADJ is typically in the range of 50uA it only adds a small error to the output voltage and should be considered when very precise output voltage setting is required. |
