10ppm/ºC, 3mV Dropout Voltage Reference Operates with Less than 1µA
Linear Technology announced the LT6656, a precision SOT23 voltage reference that operates on only 850nA of supply current. The LT6656 has an initial error of less than 0.05% and a guaranteed temperature drift of less than 10ppm/ºC. This combination of precision and ultralow power is ideal for portable, wireless and remote devices. With an output drive capability of 5mA, the LT6656 is suitable for a wide range of applications. For example, the LT6656 could serve as both the supply voltage and the precision reference for a low power, high resolution ADC. The LT6656 can replace low power shunt references, offering better efficiency and regulation in the presence of variable load current and supply voltages. For many applications, the extremely low quiescent current allows the LT6656 to remain in an always-on, stable state.
Buil“The high precision of the LT6656, combined with only 1µA of supply current packaged in a tiny SOT23, demonstrates a significant advance in voltage reference technology,” stated Brendan Whelan, design manager for Linear Technology.
