Reg LDO Lin Fix Pos 3.3V 3A 4-Pin (3+Tab) TO-263 Rail
Fixed Positive LDO Regulator, 3.3V, 1.5V Dropout, BIPolar, PSSO3
Linear Voltage Regulator IC; Supply Voltage Max:29V; Package/Case:3-TO-263; Output Current:3A; Current Rating:3A; Leaded Process Compatible:No; Output Voltage Max:3.3V; Peak Reflow Compatible (260 C):No RoHS Compliant: No
The LM1085 is a series of low dropout positive voltage regulators with a maximum dropout of 1.5V at 3A of load current. It has the same pin-out as National Semiconductor's industry standard LM317. The LM1085 is available in an adjustable version, which can set the output voltage with only two external resistors. It is also available in three fixed voltages: 3.3V, 5.0V and 12.0V. The fixed versions integrate the adjust resistors. The LM1085 circuit includes a zener trimmed band gap reference, current limiting and thermal shutdown. The LM1085 series is available in TO-220 and TO-263 packages. Refer to the LM1084 for the 5A version, and the LM1086 for the 1.5A version.
