描述 Description

The FS8844 series is a positive voltage regulator with high accuracy output voltage and ultra-low quiescent current which is typically 2.0μA. The device is ideal for handheld communication equipments and battery powered applications which require low quiescent current. The FS8844 contains a bandgap reference voltage source, an error amplifier, a P-channel pass transistor, a resistor-divider for setting output voltage, a current limiter, and temperature limit protection circuits. The high-accuracy output voltage is preset at an internally trimmed voltage 1.8V, 2.8V or 3.3V. Other output voltages can be mask-optioned from 1.2V to 5.0V with 100mV increment. The FS8844 has been designed to be used with low cost ceramic capacitors and requires a minimum output capacitor of 1.0μF. The devices are available in SOT-23 packages.
