AP131 - 300mA Low Dropout Linear Regulator

General Description

The AP131 is a 300mA, fixed output voltage, low dropout linear regulator.

The Device included pass element, error amplifier, band-gap, current limit and thermal shutdown circuitry.

The device is ON when EN pin is set to logic high level.

Key Features

  • s - Input voltage range is up to 7V - Dropout voltage 400mV at 300mA output current - Guaranteed 300mA output current. - Internal Ron =1.5Ω PMOS draws no base current - Low quiescent current 50µA - Output voltage 2% accuracy, and 1.5V to 5V with 0.1V step - Active low shutdown function (EN pin). - Fast transient response - Good load regulation - Current limit and thermal shutdown protection - SOT89-5L and SOT23-5L packages.
