TPS70918DRVR linear regulator IC Positive Fixed 1 Output 150mA 6-WSON
The TPS70918DRVR is an ultra-low quiescent current, high-input voltage, low-dropout linear regulator from Texas Instruments engineered to meet the stringent power efficiency demands of battery-powered and industrial systems. Providing a precise 1.8V fixed output voltage, this device reliably delivers up to 150mA of continuous output current, making it an ideal solution for always-on subsystems, IoT sensors, wearable electronics, and smart meters. Its defining characteristic is the extremely low 1uA quiescent current, which drastically minimizes battery drain during light-load or standby modes, thereby significantly extending the operational lifespan of portable devices. Furthermore, the regulator supports a wide input voltage range up to 36V, offering exceptional flexibility that allows it to be powered directly from multi-cell battery stacks or unregulated industrial rails without requiring extensive pre-regulation circuitry.
Delivering exceptional electrical performance, this LDO features a typical dropout voltage of 250mV at 150mA, ensuring efficient power conversion even when the input voltage closely approaches the 1.8V output. The device incorporates an active-high enable pin, allowing system controllers to completely shut down the regulator and further reduce the supply current to a mere 100nA in shutdown mode. Integrated robust protection mechanisms include active pull-down circuitry for rapid output discharge, current limiting, and thermal shutdown, reliably safeguarding sensitive downstream microcontrollers from potential damage during fault conditions. Additionally, the regulator remains stable with a small 1uF ceramic output capacitor, reducing overall component count and board space while providing solid power supply rejection ratio (PSRR) and low output noise, which is crucial for maintaining signal integrity in noise-sensitive RF transceivers and precision analog signal chains.
