PAM3102

Dual 150mA High PSRR Low-Dropout CMOS Regulator Key Features www.datasheet4u.com PAM3102 General Description The dual LDO PAM3102 series of positive voltage linear regulators feature high output voltage accuracy, low quiescent current and low dropout voltage, making them ideal for battery powered applications. The line transient response and load transient response are excellent. Their high PSRR make them useful in applications where AC noise on the input power supply must be suppressed. Space-saving SOT23-6 package for 2-ch LDOs is attractive for portable and handheld applications. They have both thermal shutdown and a current limit feature to prevent device failure under extreme operating conditions. They are stable with an output capacitance of 2.2 μ F or greater. n n n n n n n n n Output Accuracy: ± 2% Low Dropout Voltage: 180mV@150mA High PSRR: 70dB@100Hz Low Noise Output Current Limiting Short Circuit Protection Thermal Shutdown Space Saving Package SOT23-6 Pb-Free Package Applications n n n n n n Cellular Phone Portable Electronics, PDA Wireless Devices, Wireless LAN Computer Peripherals Camera Module GPS Receiver Typical Application Block Diagram IN 2 1 VIN VOUT1 VOUT2 GND 5 6 4 OUT1 OUT2 VIN Current Limit Thermal Protection Current Limit CE1 PAM3102 3 CE 2 C IN 2.2 μ F Co 2.2 μ F Co 2.2 μ F VOUT1 + V REF + VOUT2 GND CE1 Bias CE2 Power Analog Microelectronics , Inc www.poweranalog.com 09/2008 Rev 1.1 1 Dual 150mA High PSRR Low-Dropout CMO...
