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 
currentGthe 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 2.2

μF 

MLCC input capacitor and 4.7

μF 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). 

The DB1510B is packaged SOT-223, TO-252 & 
8-pin thin dual flat no lead (TDFN) package that a 
heat sink or an exposed pad for optimal power 
dissipation.
