DB1510B
1A, 0.8V Dropout LDO Regulator
Datasheet AT1510BF-01
9. Nov. 2009
1 of 8
DESCRIPTION
The DB1510B low-dropout linear regulator
operates from input voltages as low as 2.2V and
are able to deliver up to 1A of continuous output
current the DB1510B offers low dropout (typically
800mV at 1A) and low quiescent current (typically
400uA at 0.1A).

current the DB1510B offers low dropout (typically
800mV at 1A) and low quiescent current (typically
400uA at 0.1A).
Fixed output voltages of the DB1510B are 1.0V,
1.2V, 1.5V, 1.8V, 2.5V, 2.8V, 3.3V & 3.5V and the
output voltage is 2% accurate over load and line
variations. These regulators use small 2.2μF
MLCC input capacitor and 4.7μF MLCC output
capacitors to deliver 1A output current.

Soft-start reduces inrush current. The other
features include over current protection (OCP),
short-circuit protection (SCP), and thermal shut
down protection (TSD).
