# LP2985IM5-2.7 (Component) ## Description Linear Voltage Regulator IC Positive Fixed 1 Output 150mA SOT-23-5 LP2985IM5-2.7 is a low-dropout (LDO) linear voltage regulator designed to provide a stable 2.7 V output with very low quiescent current and excellent noise performance. It is optimized for battery-powered and noise-sensitive applications, offering high power supply rejection ratio (PSRR) and fast transient response. The device is housed in a compact SOT-23-5 package, making it ideal for space-constrained designs.
