Product details

Dual LDO for sequenced power rails

Control features include Enable, Power Good, Reset, and Sequencing.

Protection set and temperature grade

Over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO) are all built in. The reverse polarity protection is a real differentiator — it saves an external series diode and its associated dropout voltage, which matters when the input is close to the output headroom.

PSRR and quiescent current

PSRR is specified at 65 dB at 1 kHz. Quiescent current is 250 µA.

It is ROHS3 compliant.

Frequently asked questions

What are the exact output voltages of TPS70358PWP?

The TPS70358PWP outputs are fixed at 3.3V on one regulator and 2.5V on the other. These are factory-set; there is no adjustable version in this order code.

Is TPS70358PWP a direct replacement for TPS70358PWT?

The TPS70358PWP and TPS70358PWT share the same electrical design and output voltages. The difference is packaging: PWP ships in a tube, while PWT ships in tape-and-reel. Electrically they are interchangeable, but verify your assembly line's feeder requirements before substituting.

Does TPS70358PWP support reverse polarity protection?

Yes, reverse polarity protection is listed among the built-in protection features, along with over-current, over-temperature, and under-voltage lockout. This eliminates the need for an external protection diode on the input.

What is the PSRR of TPS70358PWP?

PSRR is specified at 65 dB at 1 kHz. This is adequate for filtering switching-regulator ripple on the input rail for sensitive analog or mixed-signal loads.
