Additional Details

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 applications 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.

Applications

Cell Phones
Low-Dropout Regulators with External Bias Supply
