BCDSEMI AZ39150T

Preliminary Datasheet
1.5A ULTRA LOW DROPOUT LINEAR REGULATOR
AZ39150
General Description
Features
The AZ39150 is low dropout three-terminal regulator
with a typical dropout of 375mV at 1.5A output current.
·
·
Minimum Guaranteed Output Current: 1.5A
Dropout Voltage: 375mV at IOUT=1.5A
·
·
·
·
Output Accuracy: 1%
Low Ground Current
Internal Current Limit and Thermal Protection
Reversed-battery and Reversed-lead Insertion
Protection
Fast Transient Response
The AZ39150 provides current limit and thermal shutdown. On-chip thermal shutdown provides protection
against any combination of high current and ambient
temperature that would create excessive junction temperatures.
·
The AZ39150 is available for 3.3V and 5.0V versions
now. It is available in the industry standard TO-220-3
and TO-263-3 power packages.
