XLP5907MFX-1.8-XC

XLP5907MFX-1.8 is an ultra-low noise, ultra-low quiescent current LDO regulator operating from a 2.2V to 5.5V supply, capable of delivering up to 250mA output current at a fixed 1.8V output voltage. Utilizing innovative design techniques, its quiescent current as low as 15μA at no load makes it well suited for battery-powered portable devices. Excellent noise rejection is achieved without additional noise bypass capacitors, while maintaining outstanding PSRR as well as line and load transient response. The combination of ultra-low noise and extremely low quiescent current maximizes battery life in portable applications. Compatible with 1μF input and output ceramic capacitors for space-constrained, high-performance applications. Available in a 5-pin SOT-23 package with an operating temperature range of -40°C to 125°C.
