LM285Z-1.2 PDF Datasheet

The LM285/LM385 series are micropower two–terminal bandgap voltageregulator diodes. Designed to operate over a wide current range of 10 mA to20 mA, these devices feature exceptionally low dynamic impedance, lownoise and stable operation over time and temperature. Tight voltagetolerances are achieved by on–chip trimming. The large dynamic operatingrange enables these devices to be used in applications with widely varyingsupplies with excellent regulation. Extremely low operating current makethese devices ideal for micropower circuitry like portable instrumentation,regulators and other analog circuitry where extended battery life is required.The LM285/LM385 series are packaged in a low cost TO–226AA plasticcase and are available in two voltage versions of 1.235 and 2.500 V asdenoted by the device suffix (see Ordering Information table). The LM285 isspecified over a –40°C to +85°C temperature range while the LM385 is ratedfrom 0°C to +70°C.The LM385 is also available in a surface mount plastic package involtages of 1.235 and 2.500 V.• Operating Current from 10 mA to 20 mA• 1.0%, 1.5%, 2.0% and 3.0% Initial Tolerance Grades• Low Temperature Coefficient• 1.0 W Dynamic Impedance• Surface Mount Package Available
