AME41EEET

Analog Microelectronics, Inc. AME41-ADJ Micropower Voltage Reference Diode n General Description The AME41-ADJ is a micropower 3-terminal band-gap voltage regulator diode with a user adjustable output voltage. 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 AME41ADJ 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. n Key Features l Small packages: SOT-23, TO-92, SO-8 l Tolerates capacitive loads l User adjustable reverse breakdown voltage 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 VR n Typical Application VS RS A DJ B andgap Cell Feedbac k Current S hunt R1 VR GND 1000pF V alue optional I R2 RS = VS - VR I 1.27 (R1 + R2) R1 VR = 1 Analog Microelectronics, Inc.
