FEATURES
DESCRIPTION
The LP2992 is a 250 mA, fixed-output voltage
2
Ultra Low Dropout Voltage
regulator designed to provide ultra low-dropout and
Specified 250 mA Output Current
low noise in battery powered applications.
Smallest Possible Size (SOT-23, WSON
Using an optimized VIP (Vertically Integrated PNP)
Package)
process, the LP2992 delivers unequaled performance
Requires Minimum External Components
in all specifications critical to battery-powered
designs:
Stable with Low-ESR Output Capacitor
<1 µA Quiescent Current when Shut Down
Dropout Voltage: Typically 450 mV @ 250 mA load,
and 5 mV @ 1 mA load.
Low Ground Pin Current at all Loads
Output Voltage Accuracy 1% (A Grade)
Ground Pin Current: Typically 1500 µA @ 250 mA
load, and 75 µA @ 1 mA load.
High Peak Current Capability
Wide Supply Voltage Range (16V Max)
Enhanced Stability: The LP2992 is stable with
output capacitor ESR as low as 5 m, which allows
Low Z
OUT
: 0.3 Typical (10 Hz to 1 MHz)
the use of ceramic capacitors on the output.
Overtemperature/overcurrent Protection
Sleep Mode: Less than 1 µA quiescent current when
40°C to +125°C Junction Temperature Range
ON/OFF pin is pulled low.
Custom Voltages Available
Smallest Possible Size: SOT-23 and WSON
packages use absolute minimum board space.
APPLICATIONS
Precision Output: 1% tolerance output voltages
Cellular Phone
available (A grade).
Palmtop/Laptop Computer
Low Noise: By adding a 10 nF bypass capacitor,
Personal Digital Assistant (PDA)
output noise can be reduced to 30 µV (typical).
Camcorder, Personal Stereo, Camera
Multiple voltage options, from 1.5V to 5.0V, are
available as standard products. Consult factory for
custom voltages.

Basic Application Circuit
*ON/OFF input must be actively terminated. Tie to V
IN
if this function is not to be used.
**Minimum capacitance is shown to ensure stability (may be increased without limit). Ceramic capacitor required for
output (see Application Hints).
***Reduces output noise (may be omitted if application is not noise critical). Use ceramic or film type with very low
leakage current (see Application Hints).

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) “Absolute Maximum Ratings” indicate limits beyond which damage to the component may occur. Electrical specifications do not apply
when operating the device outside of its rated operating conditions.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and
specifications.
(3) The ESD rating of pins 3 and 4 for the SOT-23 package, or pins 1 and 3 for the WSON package, is 1 kV.
(4) The maximum allowable power dissipation is a function of the maximum junction temperature, T
J
(MAX), the junction-to-ambient thermal
resistance, θ
J-A
, and the ambient temperature, T
A
. The maximum allowable power dissipation at any ambient temperture is calculated
using:
Where the value of θ
J-A
for the SOT-23 package is 220°C/W in a typical PC board mounting and the WSON package is 65°C/W.
Exceeding the maximum allowable dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown.
(5) If used in a dual-supply system where the regulator load is returned to a negative supply, the LP2992 output must be diode-clamped to
ground.
(6) The output PNP structure contains a diode between the V
IN
to V
OUT
terminals that is normally reverse-biased. Reversing the polarity
from V
IN
to V
OUT
will turn on this diode.

Statistical Quality Control (SQC) methods. The limits are used to calculate TI's Average Outgoing Quality Level (AOQL).
