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.
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.
The TPS709xx series is available in an SOT23-5
package.
