FEATURES
DESCRIPTION
The TPS709xx series of low-dropout (LDO) linear
regulators are ultralow quiescent current devices that
are designed for power-sensitive applications. A
precision band-gap and error amplifier provides 2%
accuracy over temperature. Quiescent current of only
1 µA makes the devices ideal solutions for battery-
powered, always ON systems that require very little
idle state power dissipation. All devices have a
thermal shutdown and current limit for safety.

2% Accuracy Over Temperature
Available in Fixed-Output Voltages:
1.5 V to 6.5 V
The LDO can be put into shutdown mode by pulling
the EN pin low. The leakage current in this mode
goes down to less than 150 nA.
