Product Description
STMicroelectronics LD39150DT33-R is a high-performance 6V voltage regulator featuring an ultra low dropout linear design optimized for microprocessor and memory applications. It operates over an input voltage range of 2.5 V to 6 V and delivers a guaranteed 1.5 A output current while maintaining a low dropout voltage (200 mV typical @ 1.5 A load).
This device is fabricated using BiCMOS technology, enabling ultra low quiescent current operation independent of load current, making it ideal for battery-operated and low power systems. The regulator provides precise output regulation with ±1.5% output voltage tolerance at room temperature (25°C).
Additional features include logic-controlled electronic shutdown mode that allows the device to be turned off to save power, as well as internal current and thermal protection circuits for enhanced device safety and longevity. The regulator is stable with ceramic capacitors, facilitating compact and efficient PCB design.
The LD39150DT33-R is available in surface mount packages such as PPAK, DPAK, and DFN6 measuring 3x3 mm, with pin count of 3 pins for easy integration in compact electronic products.
Operates from 2.5 V to 6 V input voltage. Ultra low dropout voltage as low as 40 mV at 300 mA load. Quiescent current as low as 1 μA in off mode, 2.5 mA typical during operation. Fixed and adjustable output voltages: 1.8 V, 2.5 V, 3.3 V and adjustable output voltage options.
Logic-controlled shutdown for power saving. Internal current and thermal limit protections. Suitable for microprocessor and DSP power supply applications. Stable operation with ceramic capacitors.
Applications for this regulator include microprocessor power supply, digital signal processors (DSPs) power supply, post regulation of switching supplies, and use in high efficiency linear regulator circuits. The device supports operating temperatures from -40°C to 125°C, making it suitable for industrial environments requiring high reliability.
The compact package sizes enable use in dense electronic boards where space conservation is critical.
EnvMart offers this high-quality STMicroelectronics Voltage Regulator for use in electronics and electrical power management designs, combining performance, reliability, and efficiency in a small footprint.
