The LP3982S family are high performance low dropout(LDO) voltage regulators with high PSRR, fast transient response, high accuracy, and low output noise. The devices with advanced CMOS process are suitable for many applications that require regulated supplies of up to 300mA load current. The family include standard fixed output voltages of1.2V, 1.8V, 2.8V, and 3.3V. The devices are stable with a 1.0μF~10μF ceramic output capacitor. The devices are protected from short circuit by a current limit function and from over-heating by a thermal overload protection.The devices are available in standard DFN-4(1mmx1mm) and SOT23-5 packages
