General Description
The MAX1982/MAX1983 are low-voltage, low-dropout
linear regulators with an external bias supply input. The
5V bias supply drives the gate of the internal N-channel
pass transistor, making these devices ideal for applica-
tions that require low-voltage outputs from low-voltage
inputs. The MAX1982 delivers 1.2V (±3%) at 300mA
from an input voltage of 1.25V to 5.5V. The MAX1983
delivers an adjustable output voltage from 0.8V to 2V.
The MAX1982/MAX1983 include a current-limit and
thermal shutdown that protects the regulator in the
event of a fault condition. Both devices are offered in a
6-pin SOT23 package and are specified over the
extended (-40°C to +85°C) temperature range.
