A6141K3R-12A Image

The A6141K3R-12A from AiT Semiconductor is an LDO Linear Voltage Regulator that is ideal for reference voltage source regulation after switching power, power management of MP3, PDA, DSC, mouse, PS2 games, and battery-powered equipment applications. It requires an input voltage of 3 - 40 V. This regulator provides an output voltage of 1.2 V and has a dropout voltage of 400 mV (at output voltage of 5 V). It consists of a high accuracy voltage reference, error amplifier, current limit circuit, and output driver module in a single package. This LDO regulator is fabricated based on CMOS technology and exhibits excellent load transient response with good temperature characteristics. It uses trimming techniques to maintain the output voltage accuracy within ±2%.

This RoHS-compliant voltage regulator is equipped with foldback short-circuit protection, thermal protection, and output current limit function to prevent over-current or over-temperature-related damages. It is available in a surface-mount package that measures 4.5 x 4.25 mm.
