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.
