2.8V, 3.0V or 3.3V. Other output voltages can be  
mask optioned from 1.2V to 5.0V with 100mV  
increment, except the EC49513A/L-285 which  
has 2.85V output voltage.

The EC49513A/L is also compatible with  
low ESR ceramic capacitors which give added  
output stability. This stability can be maintained  
even during load fluctuations due to the excellent  
transient response of the chip. The EC49513A/L  
devices are available in SOT23-5LUFN-6 and  
TSOT23-5 packages.
