The Texas Instruments LP5900SD-1.5 is a 150mA, ultra-low-noise, low-IQ, low-dropout voltage regulator. It is designed for applications requiring clean power, such as RF and analog circuits. The device operates with an input voltage range of 2.5V to 5.5V and provides a fixed output voltage of 1.5V. It features a low dropout voltage of 80mV typical at 150mA and a low quiescent current of 25µA typical when enabled.
Key electrical characteristics include low output voltage noise of 6.5 µVrms and a high PSRR of 75 dB at 1 kHz, making it suitable for noise-sensitive applications. The regulator includes a logic-controlled enable pin for power management and protection features such as thermal-overload and short-circuit protection.
The LP5900SD-1.5 is available in a compact 6-WSON (2.2x2.5 mm) surface-mount package. It requires a minimum load capacitance of 0.47µF and does not require a bypass capacitor for noise reduction. The operating temperature range is -40°C to 85°C.
