AME, Inc. AME385-2.5 Micropower Voltage Reference Diode n Typical Application n Functional Block Diagram l Small packages: SOT-23, TO-92, SO-8 l Tolerates capacitive loads l Fixed reverse breakdown voltage of 2.5V l Wide temperature range ----- -40oC to +85oC l Low temperature coefficient --100ppm/oC (max) l Excellent transient response The AME385-2.5 is a micropower 2-terminal band-gap voltage regulator diode. It operates over a 20µA to 20mA current range. Each circuit is trimmed at wafer sort to provide a ±0.20% and ±0.50% initial tolerance. The de- sign of the AME385-2.5 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 package as well as the space saving SOT-23. l Portable electronics l Power supplies l Computer peripherals l Data acquisition systems l Battery chargers l Consumer electronics n General Description n Features n Applications GND VR Bandgap Cell Current Shunt VS 0.1µF Value optional I RS = VR = 2.5V VR VS - VR RS
