The high accuracy output voltage is preset at an
internally trimmed voltage 1.2V, 1.5V, 1.8V, 2.5V,
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 SOT23-5L、UFN-6 and
TSOT23-5 packages.
