The LP3982IMM-ADJ is a micropower, ultra low-dropout (LDO), low-noise CMOS linear regulator from Texas Instruments, designed to deliver a maximum output current of 300 mA. It operates within an input voltage range of 2.5 V to 6 V and features a typical dropout voltage of 120 mV at full load. The device has a low quiescent current of 90 µA, making it suitable for battery-powered applications. In shutdown mode, it consumes only 1 nA, further enhancing its efficiency in portable devices. The LP3982IMM-ADJ provides a power supply rejection ratio (PSRR) of 60 dB and has an output voltage noise of 37 µV RMS across a frequency range of 10 Hz to 100 kHz. It is stable with small ceramic output capacitors, typically requiring a capacitance of 2.2 µF. The regulator includes built-in protection features such as overcurrent and overtemperature protection, ensuring reliable operation in various conditions. The device is available in an 8-pin VSSOP package, which is compatible with Maxim's MAX8860 series, facilitating easy integration into existing designs.
