Texas Instruments TPS77918 Single Output LDO, 250mA, Fixed(1.8V), Low Noise, Fast Transient Response, Low IQ, SVS TPS77918DGK

The TPS77918DGK is a 250-mA low-dropout (LDO) voltage regulator designed for efficient power management in various applications. It operates with a dropout voltage of approximately 200 mV at full load, making it suitable for battery-powered devices. The device features an integrated power-on reset function, which provides a reset output for microcontrollers and processors during power-up and undervoltage conditions. It has a quiescent current of 92 µA at full load, reducing to less than 1 µA in shutdown mode, which enhances battery life. This LDO is optimized for stability with a range of output capacitors, including low ESR ceramic and tantalum types. The TPS77918DGK offers low noise performance, with an output noise level of 55 µVrms without additional filter capacitors. It is available in a compact 8-pin MSOP package and has a voltage tolerance of 2% over specified conditions. The device is suitable for applications requiring a stable voltage supply with minimal noise and low power consumption.
