  • Pagers GENERAL DESCRIPTION The AMS3100 are two-terminal micropower band-gap voltage reference that feature a very low dynamic impedance and good temperature coefficient, operating from 1.24V to 5.3V and over a 10 µA to 20mA current range. AMS3100 is trimmed at wafer test level to optimize the temperature coefficient and tight out put voltage tolerance. The advanced process technology used, makes the AMS3100 exceptionally tolerant of capacitive loading, making it easy to use in almost any reference application. The wide dynamic operating range allows its use with widely varying supplies with excellent regulation. The extremely low power drain, makes these reference diodes useful for micropower circuitry. These voltage references can be used to make portable meters, regulators or general purpose analog circuitry w ith battery life approaching shelf life. Further more, the wid e operating current allows it to replace older re ferences with a tight tolerance part. Pin to pin compatible with other standard industry references, the AMS3100 offers the advantage of long term stability at low cost. The AMS3100 is operating over a -40°C to 85°C temperature range and is available in the space saving SOT-23 package. ORDERING INFORMATION: TOL.

Operating Ratings indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Note 2: Parameters identified with boldface type apply at temperature extremes. All other numbers apply at TA = TJ = 25°C. Note 3: Guaranteed and 100% production tested Note 4: Guaranteed but not 100% production tested. These limits are not used to calculate average outgoing quality levels. Note 5: The average temperature coefficient is defined as the maximum deviation of reference voltage at all measured temperatures between the operating TMAX and TMIN, divided by TMAX - TMIN. The measured temperatures are -40°C, 25°C and 85°C.
