3 Description
The TPS706 series of linear voltage 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 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
protection 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.
2 Applications
• Smartphones and Tablets
• Portable and Battery-Powered Applications
• Camera Modules
• Set-Top Boxes
• Wearables
• Solid State Drives
• Medical Equipment
The TPS706 series is available in WSON-6 and SOT-
23-5 packages.
