LDLN025M45R

LDLN025M45R is a 250mA ultra-low noise LDO. The very low quiescent current, which is just 12μA at no load, extends the battery life of applications requiring a very long standby time. With its ultra-low noise value and high PSRR, the LDLN025 provides a very clean output, suitable for ultra-sensitive loads. It is stable with ceramic capacitors. The enable logic control function puts the device into shutdown mode allowing a total current consumption lower than 1μA. It is designed to keep the quiescent current under control and at a low value during dropout operation, extending the operating time of battery-powered devices. Typical applications are noise-sensitive loads such as ADC, and VCO/RF modules in mobile phones and tablets, wireless LAN devices, smartphones/tablets, image sensors, and instrumentation.
