LDLN030G33R

STMicro's LDLN030G33R is a 300 mA very low-dropout voltage regulator, able to work with an input voltage ranging from 1.6 V to 5.5 V. The typical dropout voltage at 300 mA load is 150 mV. The very low quiescent current, which is just 16 μA at no-load, extends battery-life of applications requiring very long standby time. Thanks to its ultra-low noise value and high PSRR, the device provides a very clean output, suitable for ultra-sensitive loads. It is stable with ceramic capacitors. The enable logic control function puts the LDLN030G33R into shutdown mode allowing a total current consumption lower than 1 μA. The device also includes short-circuit constant current limiting, undervoltage lockout, soft-start, power good and thermal protection.Typical applications are noise sensitive loads such as ADC, VCO in mobile phones and tablets, and wireless LAN devices. The LDLN030G33R is designed to keep the quiescent current under control and at a low value also during dropout operation, helping to extend even more the operating time of battery-powered devices.<strong>Features:</strong> Ultra-low output noise: 7.5 µVRMS Provides a clean supply voltage to sensitive loads, Very low quiescent current: 16 µA at no-load Increase battery duration, Controlled lQ in dropout condition Increase better duration, Very low dropout voltage: 100 mV at 200 mA; 150 mV at 300 mA Improves efficiency, Very high PSRR: 80 dB at 100 Hz; 60 dB at 100 kHz Provides a clean supply voltage to sensitive loads, Output voltage accuracy: 2% across line, load, and temperature Provides accurate supply voltage, Logic-controlled electronic shutdown Allows remote shutdown to save battery, Power good Provides status information to the system, Internal soft-start Limits the in-rush current, Smartphones/tablets, Image sensors, Instrumentation, VCO and RF modules , HDD and SSD, Portable and other battery-powered devices
