AP131  
300mA Low Dropout Linear Regulator with Shutdown  
„ Features  
„ General Descriptions  
- Input voltage range is up to 7V  
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.  
- Dropout voltage 400mV at 300mA output current  
- Guaranteed 300mA output current.  
- Internal Ron =1.5PMOS draws no base current  
- Low quiescent current 50µA  
- Output voltage 2% accuracy, and 1.5V to 5V with  
0.1V step  
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.  
- Active low shutdown function (EN pin).  
- Fast transient response  
- Good load regulation  
- Current limit and thermal shutdown protection  
- SOT89-5L and SOT23-5L packages  
„ Applications  
- Wireless Communication  
- Battery Powered device  
- CD-ROM, DVD, and LAN Card  
- PC peripheral
