Micropower Voltage
Reference Diodes
The LM285/LM385 series are micropower two-terminal bandgap
voltage regulator diodes. Designed to operate over a wide current
range of 10 mA 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-226
plastic case and are available in two voltage versions of 1.235 V 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.
