Texas Instruments High-Performance Analog Voltage Regulators - Linear, Low Drop Out (LDO) Regulators LP3982ILDX-2.5/NOPB

The LP3982ILDX-2.5/NOPB is a micropower, ultra low-dropout (LDO) linear voltage regulator designed to deliver a maximum output current of 300mA. It operates within an input voltage range of 2.5V to 6.0V and features a typical dropout voltage of 120mV at 300mA output. The device is packaged in an 8-pin MSOP and is pin-compatible with Maxim's MAX8860, making it suitable for applications requiring space-efficient designs. This regulator is particularly advantageous for battery-powered applications due to its low quiescent current of 90µA and a shutdown mode that consumes only 1nA. It is stable with small ceramic capacitive loads, typically requiring only 2.2µF for output capacitance. The LP3982ILDX-2.5/NOPB also includes features such as thermal overload protection, current limiting, and fault detection, ensuring reliable operation in various conditions. With a typical output voltage noise of 37µV RMS and a power supply rejection ratio (PSRR) of 60dB, this regulator is well-suited for sensitive electronic applications, including wireless handsets and portable information appliances. The device's output voltage tolerance is ±2%, providing consistent performance across its operating range.
