(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
The TPS71501 low-dropout (LDO) voltage regulators
offer the benefits of high input voltage, low dropout
voltage, low-power operation, and miniaturized
packaging. The device, which operates over an input
range of 2.5 V to 24 V, is stable with any capacitor
(≥0.47 µF). The low dropout voltage and low
quiescent current allow operation at extremely low
power levels. Therefore, the devices are ideal for
powering battery-management ICs. Specifically,
because the devices are enabled as soon as the
applied voltage reaches the minimum input voltage,
the output is quickly available to power continuously
operating battery-charging ICs.
The usual PNP pass transistor has been replaced by
a PMOS pass element. Because the PMOS pass
element behaves as a low-value resistor, the low
dropout voltage, typically 415 mV at 50 mA of load
current, is directly proportional to the load current.
The low quiescent current (3.2 µA typically) is stable
over the entire range of output load current (0 mA to
50 mA).
