NOT RECOMMENDED FOR NEW DESIGN USE AP2125/2127 PAM3101 300mA HIGH PSRR LOW-DROPOUT CMOS LINEAR REGULATOR Description Pin Assignments The PAM3101 series of positive voltage linear regulators feature low quiescent current (65A typ.) and low dropout voltage, making them ideal for battery powered applications. Their high PSRR make them useful in applications where AC noise on the input power supply must be suppressed. Space-saving SOT-23, SOT-89, SC70 and DFN1.6x1.6-6L packages are attractive for portable and handheld applications. They have both thermal shutdown and current limit features to prevernt device failure from extreme operating conditions. They are stable with an output capacitor of 2.2F or greater. Features Low Dropout Voltage: 180mV 300mA (V = 3.3V) O Output Voltage Accuracy within 2% Supply Voltage Range: 2.5V to 5.5V Quiescent Current: 65A typ. High PSRR: 70dB 1kHz Excellent Line and Regulation Fast Discharge Current Limiting Short Circuit Protection Low Temperature Coefficient Shutdown Current: 0.5A Thermal Shutdown Space Saving Packages: SOT-23, SOT-89, SC70 and DFN1.6x1.6 Pb-Free Packages Applications Cellular Phones Bluetooth Earphones Digital Cameras Portable Electronics WLANs MP3 Players 1 of 25 PAM3101 May 2016 Diodes Incorporated www.diodes.com Document number: DS36419 Rev. 3 - 3 NOT RECOMMENDED FOR NEW DESIGN USE AP2125/2127 PAM3101 Typical Applications Circuit Pin Configuration and Description Pin Number Package Type 1 2 3 4 5 6 VOUT VIN GND SOT23-3 VOUT GND VIN GND VIN VOUT GND EN BYP VOUT VIN SOT23-5 GND EN NC VOUT VIN GND VIN VOUT SOT89-3 VOUT GND VIN SOT89-5 VOUT GND NC EN VIN SC-70-3L VIN VOUT GND SC70-4L EN GND VOUT VIN SC70-5L GND EN BYP VOUT VIN DFN1.6x1.6-6L NC VIN VOUT NC GND EN Pin Name Function VIN Input GND Ground VOUT Output Chip Enable (active high) EN PAM3101BABXXX----EN default floating Other part no----EN default pull high BYP Bypass Pin, need a 10nF capacitor connect to GND NC No Connection 2 of 25 PAM3101 May 2016 Diodes Incorporated www.diodes.com Document number: DS36419 Rev. 3 - 3
