BL2940
1A Low-Dropout Regulator BL2940
DESCRIPTION
The BL2940 positive voltage regulator features the ability to
source 1A of output current with a dropout voltage of typically
0.5V and a maximum of 1V over the entire temperature range.
Furthermore, a quiescent current reduction circuit has been
SOT223
included which reduces the ground current when the differential
between the input voltage and the output voltage exceeds
approximately 3V. The quiescent current with 1A of output
TO-252
current and an input-output differential of 5V is therefore only 30
mA. Higher quiescent currents only exist when the regulator is in
the dropout mode (VIN − VOUT ≤ 3V). Designed also for vehicular
TO-220
applications, the BL2940 and all regulated circuitry are protected
from reverse battery installations or 2-battery jumps. During line
transients, such as load dump when the input voltage can
TO-263
momentarily exceed the specified maximum operating voltage,
the regulator will automatically shut down to protect both the internal circuits and the load.
The BL2940 cannot be harmed by temporary mirror-image insertion. Familiar regulator
features such as short circuit and thermal overload protection are also provided.
