MAX1982 - Low-Dropout Linear Regulators

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 applications that require low-voltage outputs from low-voltage inputs.

19-2560; Rev 0; 7/02 KIT ATION EVALU E L B AVAILA Low-Voltage, Low-Dropout Linear Regulators with External Bias Supply 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 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.
