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 µ A and ideal for portable
applications. The low output noise (30 µ V
RMS
with 0.1- µ F C
NR
) is ideal for powering VCOs. These devices are
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.

TERMINAL FUNCTIONS
SOT23 SOT223 3x3 SON
NAME (DBV) (DCQ) (DRB) DESCRIPTION
PIN NO. PIN NO. PIN NO.
IN 1 1 8 Unregulated input supply
GND 2 3, 6 4, Pad Ground
EN 3 5 5 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.
NR 4 4 3 Fixed-voltage versions only. Connecting an external capacitor to this pin bypasses noise
generated by the internal bandgap, reducing output noise to low levels.
FB 4 4 3 Feedback. Adjustable-voltage version only. This is the input to the control loop error
amplifier and is used to set the output voltage of the device.
OUT 5 2 1 Output of the regulator. There are no output capacitor requirements for stability.
