低电压，低压差线性稳压器，外部偏置电源 Low-Voltage, Low-Dropout Linear Regulators with External Bias Supply

The is a low voltage, low dropout linear regulator with external bias supply in 6 pin SOT-23 package. The 5V bias supply drives gate of internal N-channel pass transistor making device ideal for applications that require low voltage outputs from low voltage inputs. It delivers an adjustable output voltage from 0.8V to 2V. It includes a current limit and thermal shutdown that protects regulator in event of a fault condition. It is used in notebook computers, VID power supplies, PDAs, cell phones and low dropout regulators with external bias supply.
