Voltage Regulators - Linear, Low Drop Out (LDO) Regulators FAQ

What is the typical dropout voltage for the TCR2LN13 at 150 mA?

The datasheet specifies a typical dropout voltage of 600 mV for the 1.3 V output version when driving a load current of 150 mA.

How does the control pin behave when left unconnected?

The control pin has a pull-down connection to ground; therefore, leaving it open results in the regulator being in the OFF state.
