STMicroelectronics Voltage Regulator DFN 6-Pin 1 A, Low Dropout, Surface Mount LD49100PU25RY

STMicroelectronics LD49100PU25RY is a high-performance voltage regulator featuring a DFN 6-pin surface mount package designed for efficient power management in electronic circuits. This device supports a maximum output current of 1 A with an input voltage range from 1.5 V to 5.5 V, making it suitable for a variety of industrial and consumer power management applications.

The regulator provides an ultra low dropout voltage of 200 mV typical at full load (1 A), ensuring reliable voltage regulation with minimal power loss. Its stability with ceramic capacitors on both input and output lowers the complexity and cost of external circuitry. The device features exceptionally low quiescent current - 20 µA typically at no load, maintaining energy efficiency during standby conditions, and just 1 µA max in off mode.

Operating over a wide temperature range from -40 °C to 125 °C, the LD49100PU25RY is suitable for demanding industrial environments requiring robust performance. This RoHS-compliant component supports environmentally responsible electronics manufacturing.
