The LM285/LM385 series are micropower two–terminal bandgap voltage  
regulator diodes. Designed to operate over a wide current range of 10 µA to  
20 mA, these devices feature exceptionally low dynamic impedance, low  
noise and stable operation over time and temperature. Tight voltage  
tolerances are achieved by on–chip trimming. The large dynamic operating  
range enables these devices to be used in applications with widely varying  
supplies with excellent regulation. Extremely low operating current make  
these 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 plastic  
case and are available in two voltage versions of 1.235 and 2.500 V as  
denoted by the device suffix (see Ordering Information table). The LM285 is  
specified over a –40°C to +85°C temperature range while the LM385 is rated  
from 0°C to +70°C.
