Housed in a compact SOT-23-5 package, this device is ideal for space-constrained applications requiring low noise and high power supply rejection ratio (PSRR). Its low dropout voltage of typically 300mV at full load ensures efficient operation even when the input voltage is close to the output. The LP2985-18DBVRM3 also features a shutdown mode that reduces quiescent current to less than 1µA, making it suitable for battery-powered devices.\u003c\/p\u003e\u003ch2\u003eDetailed Technical Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd\u003e1.8V (fixed)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Current\u003c\/td\u003e\n\u003ctd\u003e150mA (max)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDropout Voltage\u003c\/td\u003e\n\u003ctd\u003e300mV (typical at 150mA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage Range\u003c\/td\u003e\n\u003ctd\u003e2.5V to 16V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuiescent Current\u003c\/td\u003e\n\u003ctd\u003e1.2mA (typical)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShutdown Current\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;1µA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePSRR\u003c\/td\u003e\n\u003ctd\u003e65dB at 1kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Noise\u003c\/td\u003e\n\u003ctd\u003e30µVrms (10Hz to 100kHz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-40°C to +125°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage\u003c\/td\u003e\n\u003ctd\u003eSOT-23-5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFixed 1.8V output with ±2% accuracy\u003c\/li\u003e\n\u003cli\u003eLow dropout voltage: 300mV at 150mA\u003c\/li\u003e\n\u003cli\u003eLow quiescent current: 1.2mA typical\u003c\/li\u003e\n\u003cli\u003eShutdown mode with \u0026lt;1µA quiescent current\u003c\/li\u003e\n\u003cli\u003eHigh PSRR: 65dB at 1kHz\u003c\/li\u003e\n\u003cli\u003eLow output noise: 30µVrms\u003c\/li\u003e\n\u003cli\u003eThermal shutdown and current limit protection\u003c\/li\u003e\n\u003cli\u003eStable with ceramic output capacitors\u003c\/li\u003e\n\u003cli\u003eSmall SOT-23-5 package\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTarget Applications\u003c\/h2\u003e\u003cp\u003eThe LP2985-18DBVRM3 is ideal for powering sensitive analog and digital circuits in applications such as:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e5G base station power management for RF transceivers\u003c\/li\u003e\n\u003cli\u003eAutomotive dashboard displays and infotainment systems\u003c\/li\u003e\n\u003cli\u003ePortable medical devices like glucose monitors\u003c\/li\u003e\n\u003cli\u003eIndustrial sensor modules requiring low noise\u003c\/li\u003e\n\u003cli\u003eBattery-powered IoT devices (e.g., smart thermostats)\u003c\/li\u003e\n\u003cli\u003eAudio equipment (e.g., portable DACs)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 style=\"border-bottom:2px solid #eee; padding-bottom:10px; margin-top:40px;\"\u003e\n  Global Supply Chain \u0026amp; Wholesale Solutions\n\u003c\/h2\u003e\n\u003cp\u003eAt Jasin Chip, we provide professional supply chain and wholesale solutions for\n\u003cstrong\u003eLP2985-18DBVRM3\u003c\/strong\u003e.
