AZ1084C
5A LOW DROPOUT LINEAR REGULATOR
Description Features
The AZ1084C is a series of low dropout positive voltage regulators
Low Dropout Voltage: 1.35V Typical at 5A
with a maximum dropout of 1.5V at 5A of load current.
Current Limiting and Thermal Protection
Output Current: 5A
The series features on-chip thermal limiting which provides protection
Current Limit: 6.5A
against any combination of overload and ambient temperatures that
Operating Junction Temperature Range: 0 to +125C
would create excessive junction temperatures. It also includes a
trimmed bandgap reference and a current limiting circuit.
