AP131 300mA Low Dropout Linear Regulator with Shutdown Features - 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 General Descriptions 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. The characteristics of low dropout voltage and less quiescent current make it good for some critical current application, for example, some battery powered devices. The typical quiescent current is approximately 50µA from zero to maximum load. Due to internal flexible design, result in extensively fixed output voltage versions and make it convenient to use for applications. Built-in current-limit and thermal-shutdown functions prevent any fault condition from IC damage. An external capacitor can be connected to the BP pin and reduce the output noise.

Dropout voltage is defined as the input to output differential voltage. Dropout is measured at constant junction temperature by using pulsed ON time, and the criterion is VOUT inside target value ±2%. This test is skipped at the condition of VIN
