TPS709 is an 150-mA, 30-V, Ultra-Low IQ, Wide Input Low-Dropout Regulator with Reverse Current Protection

This post sponsored by Texas Instruments.

The TPS709xx series of linear regulators are ultralow, quiescent current devices designed for power-sensitive applications. A precision band-gap and error amplifier provides 2% accuracy over temperature. Quiescent current of only 1 µA makes these devices optimal 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. These regulators can be put into shutdown mode by pulling the EN pin low. The shutdown current in this mode goes down to 150 nA, typical. The TPS709xx series is available in WSON-6 and SOT-23-5 packages. TPS709 supports an input voltage range of 2.7 V to 30 V, as well as 200-mA Peak Output. It is available in fixed-output voltages of 1.2 V to 6.5 V. TPS709 applications include Zigbee™ Networks, home automation, metering, weighing scales, portable power tools, remote control devices, wireless handsets, smart phones, PDAs, WLAN, and white goods.
