LM285Z-2.5G

Micropower Voltage  Reference Diodes

参考电压 2.5V 10uA-20mA

The LM285Z-2.5G 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 LM285Z-2.5G 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.

The LM385 is also available in a surface mount plastic package in voltages of 1.235 V and 2.500 V.
