Ultra-low quiescent current devices designed for power-sensitive applications

This post is sponsored by Texas Instruments. The TPS709, a 150mA, 30V, ultra-low IQ, wide input low-dropout regulator with reverse current protection is now available from Texas Instruments (TI). The TPS709xx series of ultralow, quiescent current linear regulators is designed for power-sensitive applications. A precision band-gap and error amplifier provides 2% accuracy over temperature. Quiescent current of only 1µA makes these devices ideal solutions for battery-powered, always-on systems that require very little idle-state power dissipation. These devices have thermal-shutdown, current-limit, and reverse-current protections for added safety. The regulators can be put into shutdown mode by pulling the EN pin low. The shutdown current in this mode goes down to 150nA, typical. The TPS709xx series is available in WSON-6 and SOT-23-5 packages.
