NOT RECOMMENDED FOR NEW DESIGN USE AP2127N/K/AP2125KS PAM3103 300mA ADJUSTABLE HIGH PSRR CMOS LINEAR REGULATOR Description Pin Assignments The PAM3103 is a positive, adjustable linear regulator. It features low quiescent current (65A typ.) and low dropout voltage, making it ideal for battery powered applications. The output voltage is adjustable from 1.2V through 5V. Its high PSRR makes it useful in applications that require AC noise suppression on the input power supply. Space- saving SOT23-5 and SOT353(SC70-5) packages are attractive for portable and handheld applications. It has both thermal shutdown and a current limit features to prevent device failure under extreme operating conditions. It is stable with an output capacitor of 2.2F or greater. Features Low Dropout Voltage: 180mV 300mA ( V = 3.3V) O Accuracy within 2% Quiescent Current: 65A Typ. High PSRR: 67dB 100Hz Excellent Line/Load Regulation Fast Response Current Limiting Short Circuit Protection Low Temperature Coefficient Shutdown Current: 0.5A Thermal Shutdown Applications Space Saving Packages SOT23-5 and SOT353(SC70-5) Pb-Free Package Cordless Phone Cellular Phone Bluetooth Earphone Digital Camera Portable Electronics WLAN MP3 Player Typical Applications Circuit V = V *(R1+R2)/R2 O REF 1 of 11 PAM3103 May 2016 Diodes Incorporated www.diodes.com Document number: DS36410 Rev. 2 - 3 NOT RECOMMENDED FOR NEW DESIGN USE AP2127N/K/AP2125KS PAM3103 Pin Descriptions Pin Pin Function Number Name 1 VIN Input 2 GND Ground 3 EN Chip Enable (Active High) 4 ADJ Adjustable Pin Output 5 VOUT Functional Block Diagram Absolute Maximum Ratings ( T = +25C, unless otherwise specified.)
