Low-Voltage, Low-Dropout Linear Regulators

with External Bias Supply

General Description

Features

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 ( 3ꢀ% at 3ꢁꢁmA

from an input voltage of 1.25V to 5.5V. The MAX1983

delivers an adjustable output voltage from ꢁ.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 (-4ꢁ°C to +85°C% temperature range.
