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.

The TPS706 series is available in WSON-6 and SOT-23-5 packages.

Pin Functions

PIN I/O DESCRIPTION
NAME NO.
DRV DBV
EN 4 3 I Enable pin. Driving this pin high enables the device. Driving this pin low puts the device into low current shutdown. This pin can be left floating to enable the device. The maximum voltage must remain below 6.5 V.
GND 3 2 — Ground
IN 6 1 I Unregulated input to the device
NC 2, 5 4 — No internal connection
OUT 1 5 O Regulated output voltage. Connect a small 2.2-µF or greater ceramic capacitor from this pin to ground to assure stability.
Thermal pad — — The thermal pad is electrically connected to the GND node.
Connect to the GND plane for improved thermal performance.
