Analog Microelectronics, Inc. AME385-1.2 Micropower Voltage Reference Diode nnnnn General Description The AME385-1.2 is a micropower 2-terminal band-gap voltage regulator diode. It operates over a 15µA to 20mA current range. Each circuit is trimmed at wafer sort to provide a ±0.2% and ±0.5% initial tolerance. The de- sign of the AME385-1.2 allows for a large range of load capacitances and operating currents. The low start-up current makes these part ideal for battery applications. Analog Microelectronics offers this part in a TO-92 and SO-8 packages as well as the space saving SOT-23. nnnnn Key Features l Small packages: SOT-23, TO-92, SO-8 l Tolerates capacitive loads l Fixed reverse breakdown voltage of 1.235V l Low temperature coefficient --- 100ppm/oC (max) l Excellent transient response nnnnn Typical Application nnnnn Applications l Portable electronics l Power supplies l Computer peripherals l Data acquisition systems l Battery chargers l Consumer electronics nnnnn Functional Block Diagram GND VR Bandgap Cell Feedback Current Shunt VS 1000pF Value optional IRS = VR = 1.235V VR VS - VR RS I
