PAM3103

PAM3103 300mA Adjustable High PSRR CMOS Linear Regulator Features www.datasheet4u.com General Description The PAM3103 is a positive, adjustable linear regulator. It features low quiescent current (65 μ A 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 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 2.2 μ F or greater. n Low Dropout Voltage: 180mV@ 300mA ( V O= 3.3V) n Accuracy within ±2% n Quiescent Current: 65 μ A Typ. n High PSRR: 67dB@100Hz n Excellent Line/Load Regulation n Fast Response n Current Limiting n Short Circuit Protection n Low Temperature Coefficient n Shutdown Current: 0.5 μ A n Thermal Shutdown n Space Saving Packages SOT2 3-5 and SC70-5 n Pb-Free Package Applications n n n n n n n Cordless Phone Cellular Phone Bluetooth Earphone Digital Camera Portable Electronics WLAN M P 3 Player Typical Application IN 1 5 Block Diagram VIN OUT VOUT VIN EN GND 2 VOUT PAM3103 3 ADJ 4 R1 CC 100pF OverCurrent Shutdown C IN 1μF R2 CO 2.2 μ F EN Thermal Protection ADJ Error Amp V O= V REF* ( R1 + R2 ) /R2 Reference GND Power Analog Microelectronics , Inc www...
