A Page 2 of 3 SLLM317L Elektronische Bauelemente 100mA Adjustable Voltage Regulator The SLLM317L provides an internal reference voltage of 1.25V between the output and adjustments terminals. This is used to set a constant current flow across an external resistor driver, giving an output voltage VOUT of: VOUT = VREF * (1 + R2 / R1) + IADJ * R2 The device is designed to minimize the term IADJ (100uA max) and to maintain it very constant with line and load charges. Usually, the error term IADJ*R2 can be neglected. To obtain the previous requirement, all the regulator quiescent current is returned to the output terminal, imposing a minimum load current condition. If the load is insufficient, the output voltage will rise. The SLLM317L is a floating regulator, input-output differential voltage, supplies of very high voltage with respect to ground can be regulated as long as the maximum input-output differential is not exceeded. Furthermore, programmable regulators are easily obtainable and, by connecting a fixed resistor between the adjustment and output, the device can be used as a precision current regulator.
