LM285, LM385B
Micropower Voltage Reference Diodes
The LM285/LM385 series are micropower two−terminal bandgap
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.
The LM385 is also available in a surface mount plastic package in
voltages of 1.235 V and 2.500 V.
Features
• Pb−Free Packages are Available
• Operating Current from 10 mA to 20 mA
• 1.0%, 1.5%, 2.0% and 3.0% Initial Tolerance Grades
• Low Temperature Coefficient
• 1.0 W Dynamic Impedance
• Surface Mount Package Available

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.
