Housed in a 6-lead DFN package with a 3x3 mm footprint, this device delivers up to 1A of output current with an ultra-low dropout voltage of typically 200mV at full load. The LD49100PURY operates over a wide input voltage range from 1.5V to 5.5V and provides an adjustable output voltage from 0.8V to 5.5V, making it suitable for powering low-voltage digital cores, analog circuits, and RF blocks. Its high PSRR (power supply rejection ratio) of 70dB at 1kHz and low output noise of 30µV RMS ensure clean power delivery for noise-sensitive applications. The device also features enable control, current limiting, and thermal shutdown protection.\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 Current\u003c\/td\u003e\n\u003ctd\u003e1 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDropout Voltage (Typ)\u003c\/td\u003e\n\u003ctd\u003e200 mV @ 1A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Voltage Range\u003c\/td\u003e\n\u003ctd\u003e1.5 V to 5.5 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage Range\u003c\/td\u003e\n\u003ctd\u003e0.8 V to 5.5 V (Adjustable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePSRR @ 1kHz\u003c\/td\u003e\n\u003ctd\u003e70 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Noise (10Hz-100kHz)\u003c\/td\u003e\n\u003ctd\u003e30 µV RMS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuiescent Current\u003c\/td\u003e\n\u003ctd\u003e55 µA (Typ)\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\u003e6-DFN (3x3 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eUltra-low dropout voltage: 200mV typical at 1A\u003c\/li\u003e\n\u003cli\u003eHigh PSRR: 70dB at 1kHz\u003c\/li\u003e\n\u003cli\u003eLow output noise: 30µV RMS\u003c\/li\u003e\n\u003cli\u003eAdjustable output voltage from 0.8V to 5.5V\u003c\/li\u003e\n\u003cli\u003eEnable pin for power sequencing\u003c\/li\u003e\n\u003cli\u003eCurrent limiting and thermal shutdown protection\u003c\/li\u003e\n\u003cli\u003eStable with ceramic capacitors\u003c\/li\u003e\n\u003cli\u003eRoHS compliant and halogen-free\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTarget Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e5G base station power management (e.g., powering FPGA cores)\u003c\/li\u003e\n\u003cli\u003eAutomotive dashboard displays and infotainment systems\u003c\/li\u003e\n\u003cli\u003ePortable medical devices (e.g., glucose monitors)\u003c\/li\u003e\n\u003cli\u003eIndustrial sensors and IoT modules\u003c\/li\u003e\n\u003cli\u003eWireless communication equipment (e.g., Wi-Fi modules)\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\u003eLD49100PURY\u003c\/strong\u003e.
