MOTOROLA ANALOG IC DEVICE DATA
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
A 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.
The LM385 is also available in a surface mount plastic package in
voltages of 1.235 and 2.500 V.
