Analog Microelectronics, Inc. Micropower Voltage Reference Diode AME41-1.2 n General Description n Key Features The AME41-1.2 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 ±0.20% and ±0.50% initial tolerance. The design of the AME41-1.2 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. l Small packages: SOT-23, TO-92, SO-8 l Tolerates capacitive loads l Fixed reverse breakdown voltage of 1.25V l Tight voltage tolerance ---------- ±0.20%, ±0.50% l Wide operating current ---------- 15µA to 20mA l Wide temperature range -------- -40oC to +85oC l Low temperature coefficient --- 100ppm/oC (max) l Excellent transient response n Applications l l l l l l Portable electronics Power supplies Computer peripherals Data acquisition systems Battery chargers Consumer electronics n Functional Block Diagram n Typical Application VR VS RS B andgap Cell Feedbac k GND Current S hunt VR V R = 1.25V RS = 1 I 1000pF V alue optional VS - VR I Analog Microelectronics, Inc.
