STMicroelectronics LDLN025J18R is a positive fixed output linear voltage regulator designed for applications requiring precise voltage regulation and low power consumption. This component delivers a stable 1.8V output with a maximum current capability of 250mA. The device features an extremely low quiescent current of 25µA, making it suitable for battery-powered and low-power designs. Key protection mechanisms include over current, over temperature, and short circuit protection, along with a soft-start feature to manage inrush current. The regulator exhibits high Power Supply Rejection Ratio (PSRR) performance, ranging from 80dB at 100Hz to 60dB at 100kHz, effectively filtering noise from the input supply. It operates over a wide temperature range of -40°C to 125°C (TJ) and has an input voltage range up to 5.5V. The LDLN025J18R is supplied in a compact 4-FlipChip package, ideal for space-constrained surface mount applications. Its low dropout voltage of 0.2V at 250mA ensures efficient operation even with minimal voltage headroom. This LDO regulator finds utility in various industries including consumer electronics, industrial control, and automotive systems.
