The TPS736xx family of low-dropout (LDO) linear voltage regulators uses a new topology—an NMOS pass

element in a voltage-follower configuration. This topology is stable using output capacitors with low ESR and

allows operation without a capacitor. It also provides high reverse blockage (low reverse current) and ground-pin

current that is nearly constant over all values of output current.

The TPS736xx uses an advanced BiCMOS process to yield high precision while delivering low dropout voltages

and low ground-pin current. Current consumption, when not enabled, is under 1

µA and ideal for portable

applications. The low output noise (30

µV

protected by thermal shutdown and foldback current limit.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more

susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Enable. Driving EN high turns on the regulator. Driving this pin low puts the regulator into

shutdown mode. See the Shutdown section under Applications Information for more details.

EN can be connected to IN if not used.

Fixed-voltage versions only. Connecting an external capacitor to this pin bypasses noise

generated by the internal bandgap, reducing output noise to low levels.
