1.5A ULTRA LOW DROPOUT LINEAR REGULATOR  
AZ39151  
General Description  
Features  
The AZ39151 is a 1.5A, high accuracy linear voltage  
regulator. It features 375mV dropout voltage at 1.5A  
output current and low ground current over all operat-  
ing conditions .  
·
·
Minimum Guaranteed Output Current: 1.5A  
Low Dropout Voltage: 375mV at I  
=1.5A  
OUT  
·
·
·
·
Output Accuracy: ±1%  
Low Ground Current  
Internal Current and Thermal Limit  
Reversed-battery and Reversed-lead Insertion  
Protection  
The AZ39151 is specifically designed for low voltage,  
high current output systems, such as PC add-in cards  
where their tiny dropout voltage and ground current  
values are important attributes.  
·
·
Fast Transient Response  
TTL/CMOS Compatible Enable Pin  
The AZ39151 has 5.0V version only.  
Applications  
The AZ39151 is available in TO-252-4 (PPAK) pack-  
age.

Note 2: Output voltage temperature coefficient is defined as the worst case voltage change divided by the total temperature  
range.  
Note 3: Dropout voltage is defined as the input-to-output differential when the output voltage drops to 99% of its nominal value  
which is measured at VOUT+1V applied to VIN
