General Description
The MAX8556/MAX8557 low-dropout linear regulators
operate from input voltages as low as 1.425V and are
able to deliver up to 4A of continuous output current
with a typical dropout voltage of only 100mV. The out-
put voltage is adjustable from 0.5V to V
IN
- 0.2V.
Designed with an internal p-channel MOSFET pass tran-
sistor, the MAX8556/MAX8557 maintain a low 800μA typi-
cal supply current, independent of the load current and
dropout voltage. Using a p-channel MOSFET eliminates
the need for an additional external supply or a noisy inter-
nal charge pump. Other features include a logic-con-
trolled shutdown mode, built-in soft-start, short-circuit
protection with foldback current limit, and thermal-over-
load protection. The MAX8556 features a POK output that
transitions high when the regulator output is within ±10%
of its nominal output voltage. The MAX8557 offers a
power-on reset output that transitions high 140ms after the
output has achieved 90% of its nominal output voltage.
The MAX8556/MAX8557 are available in a 16-pin thin
QFN 5mm x 5mm package with exposed paddle.
