IRU1010-25  
1A LOW DROPOUT POSITIVE  
FIXED 2.5V REGULATOR  
FEATURES  
DESCRIPTION  
Guaranteed < 1.3V Dropout at Full Load Current  
Fast Transient Response  
The IRU1010-25 is a low dropout three-terminal fixed out-  
put regulator with minimum of 1A output current capabil-  
ity. This product is specifically designed to provide well  
regulated supply for low voltage IC applications as well  
as generating clock supply for PC applications. The  
IRU1010-25 is guaranteed to have <1.3V dropout at full  
load current making it ideal to provide well regulated with  
3.8V input supply. The IRU1010-25 is specifically de-  
signed to be stable with low cost aluminum capacitors  
while maintaining stability with low ESR tantalum caps.  
1% Voltage Reference Initial Accuracy

Note 1: Low duty cycle pulse testing with Kelvin connections is required in order to maintain accurate data.  
Note 2: Dropout voltage is defined as the minimum differential voltage between VIN and VOUT required to maintain  
regulation at VOUT. It is measured when the output voltage drops 1% below its nominal value.
