Other Parts Discussed in Thread: TPS62091, TPS62093

Hello TI Team,

We are working on a project, there many TI regulators, LDOs and Load switches are being used. 

TPS62090, TPS62091 and TPS62093 are among those parts. 

I have one query related to the TPS6209x regulators. 

In the datasheet the description of the EN (Enable) pin is given as follows- 

(EN: - Device enable. To enable the device this pin needs to be pulled high. Pulling this pin low disables the device. This pin has a pull down resistor of typically 400 kΩ, which is active when EN is low.)

Query: - I want to know the status of regulator (ON/ OFF) when EN pin is left floating (Unconnected). 

 

Thank You 

Raj Kumar
