QX6206 系列是高纹波抑制率、低功耗、低压差CMOS 降压型电压稳压器。

QX6206具有很低的静态电流(典型值为8.0μA),它们能在输入、输出电压差极小的情况下提供300mA的输出电流,并且仍能保持良好的调整率。

QX6206内置了过流保护和短路保护功能。

由于输入输出间的电压差很小和静态偏置电流很小,QX6206特别适用于需要延长电池使用寿命的电池供电类产品,如计算机、消费类产品和工业设备等,也可以作为调整器和参考电压来使用。

QX6206系列产品总共有三种封装形式:SOT23SOT23-3SOT89-3

QX6206 Low Dropout Linear Regulator

The QX6206 series is a high ripple rejection ratio, low power consumption, low dropout CMOS step-down voltage regulator.

QX6206 has a very low quiescent current (typical value is 8.0μA), they can provide 300mA output current in the case of very small input and output voltage difference, and still maintain a good regulation rate.

QX6206 has built-in over-current protection and short-circuit protection.

Due to the small voltage difference between the input and output and the small static bias current, the QX6206 is particularly suitable for battery-powered products that require extended battery life, such as computers, consumer products, and industrial equipment. It can also be used as a regulator and reference Voltage to use.

QX6206 series products have three package types: SOT23, SOT23-3 and SOT89-3.

Ø High precision output voltage: ± 2%

Ø Output voltage: 2.0V ~ 5.0V (stepping 0.1V)

Ø Low quiescent current: 8uA

Ø Strong load capacity: when VIN = 4.3V and VOUT = 3.3V, IOUT = 300mA

Ø Very low input and input voltage difference: 0.2V@80mA

Ø Good output stability: the typical power supply voltage adjustment rate is 0.05% / V

Ø Low temperature adjustment coefficient
