AP131-15WL-7

NOT RECOMMENDED FOR NEW DESIGN USE AP7343 AP131 300mA LOW DROPOUT LINEAR REGULATOR WITH SHUTDOWN Description Pin Assignments The AP131 is a 300mA, fixed output voltage, low dropout linear regulator. The Device included pass element, error amplifier, bandgap, current limit and thermal shutdown circuitry. The device is ON when the EN pin is set to logic high level. ( Top View ) IN The characteristics of low dropout voltage and less quiescent current make it good for some critical current applications, for example, some battery powered devices. The typical quiescent current is approximately 50µA from zero to maximum load. Due to the internal flexible design, it results in extensively fixed output voltage versions and makes 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. 1 EN 3 • • • • • • • • • • • • • • • • • • Notes: 4 BP SOT25 Applications • • OUT GND 2 Features Input Voltage Range is from 2.7V to 5.5V 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: 1.5V/1.8V/2.0V/2.5V/2.8V/ 2.9V/3.0V/3.3V/ 3.5V; Accuracy 2% Active Low Shutdown Function (EN pin) Fast Transient Response Good Load Regulation Current Limit and Thermal Shutdown Protection Short-Circuit Current Fold-Back Lead Free package: SOT25 SOT25: Available in “Green” Molding Compound (No Br, Sb) Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free. “Green” Device (Note 3) 5 Battery Powered Device Wireless Communication CD-ROM, DVD, and LAN Card PC Peripheral 1.
