(1) Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.

DESCRIPTION/ORDERING INFORMATION
The TPS72118 family of LDO regulators is available in fixed voltage options that are commonly used to power
the latest DSPs and microcontrollers with a fixed output to 1.8 V. These regulators can be used in a wide variety
of applications ranging from portable, battery-powered equipment to PC peripherals. The family features
operation over a wide range of input voltages (1.8 V to 5.5 V) and low dropout voltage (150 mV at full load).
Therefore, compared to many other regulators that require 2.5 V or higher input voltages for operation, these
regulators can be operated directly from two AAA batteries. Also, the typical quiescent current (ground pin
current) is low, starting at 85 µA during normal operation and 3 µA in shutdown mode. These regulators can be
operated very efficiently and, in a battery-powered application, help extend the longevity of the device.
Similar LDO regulators require 1 µF or larger output capacitors for stability. However, this regulator uses an
internal compensation scheme that stabilizes the feedback loop over the full range of input voltages and load
currents with output capacitances as low as 0.1 µF. Ceramic capacitors of this size are relatively inexpensive and
available in small footprints.
