Advanced Monolithic Systems AMS5010 1.2V VOLTAGE REFERENCE RoHS compliant FEATURES APPLICATIONS • Low Temperature Coefficient •Wide Operating Current Range: 50µA to 5mA • Low Output Impedance: 0.6Ω Typ. • Superior Replacement for Other 1.2V References • No Frequency Compensation Required • Low Cost • Battery Powered Systems • Instrumentation • A/D, D/A Converters • Monitors/ VCR/ TV • Current sources 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. ORDERING INFORMATION: MAX.

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: For elevated temperature operation, Tj max is ≤+150°C Thermal Resistance ϕ JA (junction to ambient) TO-92 TO-52 170°C/W (0.125” leads) 140°C/W 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 TMAX and TMIN, divided by TMAX - TMIN.
