LMC7660IMX/NOPB

The LMC7660IMX/NOPB is a high-performance, low-dropout (LDO) linear voltage regulator manufactured by Texas Instruments. It is designed to provide a stable and precise output voltage to power sensitive electronic circuits.

Description:

The LMC7660IMX/NOPB is a low-dropout linear regulator that operates from an input voltage range of 2.5V to 5.5V and provides an adjustable output voltage from 0.8V to 5V. It has a very low dropout voltage of typically 180mV at 1A load, making it suitable for battery-powered applications where input voltage can be close to the output voltage.

Features:

1. Low Dropout Voltage: The LMC7660IMX/NOPB has a low dropout voltage of 180mV, which allows it to maintain a stable output voltage even when the input voltage is close to the output voltage.
2. Adjustable Output Voltage: The output voltage can be adjusted from 0.8V to 5V using an external resistor network, providing flexibility for various applications.
3. High PSRR: The LMC7660IMX/NOPB has a high power supply rejection ratio (PSRR) of -80dB at 1kHz, which minimizes the impact of input voltage noise on the output voltage.
4. Low Quiescent Current: The quiescent current of the LMC7660IMX/NOPB is typically 70µA, which helps to conserve power in battery-powered applications.
5. Output Short Circuit Protection: The LDO provides output short circuit protection to prevent damage to the regulator or the connected load in case of a short circuit.
6. Small Package: The LMC7660IMX/NOPB is available in a compact 10-pin, 3mm x 3mm WSON package, making it suitable for space-constrained applications.
