Low Dropout Positive Voltage Regulators, from:

LM1084IT-3.3 LM1084IT-5.0 LM1085IT-3.3 LM1085IT-5.0

All products are RoHS compliant

Datasheets: [ LM1084 ]   [ LM1085 ]

The LM1084 and LM1085 are high output current linear positive voltage regulators with a typical dropout of 1.3V and maximum dropout of 1.5V at maximum load current and over the entire junction temperature range (-40÷125°C). Two fixed voltages: 3.3V and 5.0V  are available. Both devices contain current limiting and thermal shutdown circuitry. The pin-out is the same as industry standard LM317.

Applications: switching DC/DC converters, battery chargers.
