MAX872ESA

The MAX872ESA is a type of 10 uA,low-dropout,precision voltage references, which combines ultra-low quiescent current and low 200mV dropout makes it suited for battery-powered equipment. Its source and sink can reach 500 A with only 200mV input voltage headroom, which makes the 2.5V MAX872ESA ideal for use with a 3V supply . Initi al accuracy of 0.2% at +25°C (±5mV for the MAX872, ±8mV for the MAX874) and low 40ppm/°C max drift make the reference suitable for a variety of precision applications.

Features of the MAX872ESA are:(1)output voltage is 2.500V ±0.2% ;(2)wide operating voltage range is 2.7V to 20V;(3)10A max supply current;(4)40ppm/°C max drift over extended temp. range;(5)line regulation over temp is 20 V/V;(6)load regulation over Temp is 0.6mV/mA max ;(7)±500A sink/source current.

The absolute maximum ratings and electrical characteristics((VIN = 2.7V, IL = 0mA, TA = +25°C, unless otherwise noted) of the MAX872ESA can be summarized as:(1):supply voltage is 24V;(2):output short-circuit duration is cont inuous to either supply;(3):ccOMP input is -0.3V to VOUT;(4):TRIM input is -0.3V to (VIN + 0.3V); (5):TRIM output is -0.3V to (VIN + 0.3V);(6)continuous power dissipation (TA = +70°C),plastic DIP (derate 9.09mW/°C above +70°C) is 727mW,so (derate 5.88mW/°C above +70°C) is 471mW;(7)operating temperature ranges:MAX87_C_is 0°C to +70°C,MAX87_E_is-40°C to +85°C;(8):storage temperature ranges from -65°C to +150°C;junction temperature ranges from -65°C to +160°C;(9):lead temperature (soldering, 10sec) is +300°C.Electrical characteristics:(1):out put voltage is  2.495V min, 2.500V typ and 2.505 V max;(2):output voltage noise is 60Vp-p typ;(3):line regulation is 4V/V when VIN is 4.5V to 20V;(4):quiescent supply current is 6.5 uA typ and 10 uA max;(5):change in supply curre nt is 0.35 A/V typ and 0.55 A/V max when VIN is 2.7V to 20V;(6):short-circuit output current is 3mA typ and 9 mA max when VOUT is short to VIN.
