FEATURES

DESCRIPTION

The TPS715xx low-dropout (LDO) voltage regulators

• Qualified for Automotive Applications

offer the benefits of high input voltage, LDO voltage,

– Automotive grade 1 (Q-temperature range)

low-power operation, and miniaturized packaging.

– Device HBM ESD Classification Level H2

The devices, which operate over an input range of

2.5 V to 24 V, are stable with any capacitor

current allow operations at extremely low power

• Low 3.2-μA Quiescent Current at 50 mA

levels. Therefore, the devices are ideal for powering

battery-management ICs. Specifically, since the

reaches the minimum input voltage, the output is

• Available in 2.5 V, 3 V, 3.3 V, 5 V, and

battery-charging ICs.

• Minimum/Maximum Specified Current Limit

The usual PNP pass transistor has been replaced by

Current is conducted from the output to the input and is not internally limited. If extended reverse voltage operation is anticipated, external limiting might be appropriate.
