1 of 10
DESCRIPTION
The DB1514A is a very low dropout voltage linear
regulator which can operate from the input
voltages as low as 2.5V and is capable of
delivering the continuous output load current up
to 1.5A.
regulator which can operate from the input
voltages as low as 2.5V and is capable of
delivering the continuous output load current up
to 1.5A.
It has a low dropout voltage (maximum 300mV at
1A), a very low quiescent current (typically 300uA
at 0.1A) and very high PSRR up to 86dB at 1A
load current.
