MAX872

Overview
19-0005; Rev 2; 6/97 10µA, Low-Dropout, Precision Voltage References General Description The MAX872/MAX874 precision 2.
5V and 4.
096V micropower voltage references consume a maximum of only 10µA and operate from supply voltages up to 20V.
The combination of ultra-low quiescent current and low 200mV dropout makes them ideal for battery-powered equipment.
They source and sink up to 500µA with only 200mV input voltage headroom, which makes the 2.
5V MAX872 ideal for use with a 3V supply and the 4.
096V MAX874 ideal for use with a 5V supply.
Initial accuracy of 0.
2% at +25 °C (±5mV for the MAX872, ±8mV for the MAX874) and low 40ppm/°C max drift make these references suitable for a wide range of precision applications.
