The STMicroelectronics LD49300PT08R is a high-bandwidth, low-dropout linear voltage regulator capable of delivering up to 3A. It is designed for powering core voltages of low-power microprocessors and other digital ICs.
This device operates with an input voltage range of 1.4V to 5.5V and requires a separate bias supply between 3V and 6V. It offers an adjustable output voltage starting from 0.8V, with fixed options available from 0.8V to 1.8V. Key electrical features include a maximum dropout voltage of 400mV at 3A, ±1.5% initial tolerance, excellent line and load regulation, and a fast transient response up to 10MHz bandwidth.
Protection features include over-current and over-temperature shutdown. The LD49300PT08R is stable with ceramic capacitors and requires a minimum output capacitance for stability. It is supplied in a PPAK surface mount package, specifically TO-252-5, DPak (4 Leads + Tab), TO-252AD.
Applications include graphics processors, PC add-in cards, microprocessor core voltage supplies, low voltage digital ICs, high efficiency linear power supplies, and SMPS post regulators.
