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

XXX

performance and environmental limits.

TPS75125-EP is a low-dropout regulator with a power good (PG) function. Quiescent current is 75

μA at full load

and drops down to 1

μA when the device is disabled. TPS75125-EP is designed to have fast transient response

for larger load current changes.

Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low and is directly

proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the

quiescent current is very low and independent of output loading (typically 75

μA over the full range of output

current, 1 mA to 1.5 A). These two key specifications yield a significant improvement in operating life for

battery-powered systems.

The device is enabled when the enable (EN) input is connected to a low-level voltage. This low dropout (LDO)

device also features a sleep mode; applying a TTL high signal to EN shuts down the regulator, reducing the

quiescent current to less than 1

The TPS75125-EP power good (PG) terminal is an active-high, open-drain output that can be used to implement

a power-on reset or a low-battery indicator.

The TPS75125-EP is offered in a 2.5 V fixed-voltage version. Output voltage tolerance is specified as a

maximum of 3% over line, load, and temperature ranges. The TPS75125-EP is available in a 20-pin TSSOP

(PWP) package.
