GENERAL DESCRIPTION

The AMS5010 is a two-terminal band-gap voltage reference diode, which provides a fixed 1.22V output voltage. This device
features a low output impedance and low temperature coefficient, operating over a 50µA to 5mA current range. The
AMS5010 is ideal for usage in battery power instrument application as well as a reference for CMOS A/D converters.

The AMS5010NT, MT, LN, HN, GH grades are specified operational over a temperature range of 0°C to 70°C while
AMS5010LT, KT, JT grades are rated over the full -55°C to +125°C temperature range. The AMS5010 is available in TO-92
and TO-52 (metal can) packages.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. 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 3: Optimum performance is obtained at currents below 500µA. For current operation below 200µA, stray shunt capacitances should be limited to 20pF or

increased to 1µF. If strays can not be avoided, a shunt capacitor of at least 1000pF is recommended.

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 T

and T
