Product details

Fixed 3.3 V rail for noise-sensitive loads

The Texas Instruments TLV75533PDBVR is a fixed-output 3.3 V LDO rated for 500 mA continuous output. PSRR is 52 dB from 1 kHz through 1 MHz.

Dropout headroom and thermal planning

At 500 mA the dropout is specified at 0.238 V maximum. Over-current and over-temperature protection are built in.

Active lifecycle — no LTB concern

This part carries an active product status and is ROHS3 compliant. For new designs and production BOMs it is a current-generation choice; no forced migration horizon.

Frequently asked questions

What is TLV75533PDBVR's PSRR rating?

PSRR is 52 dB across the 1 kHz to 1 MHz frequency range. That is a wide-bandwidth specification — effective at switching-regulator ripple frequencies and digital noise from nearby clocks.

How do I enable the output on TLV75533PDBVR?

The device has an enable pin. Drive it high to enable the output; pull low to shut down the regulator and reduce quiescent current to near zero. No external pull-up or pull-down is required — the pin has an internal current source.

What is the closest pin-compatible alternative to TLV75533PDBVR?

The LP2985 from Texas Instruments is a common cross-shop candidate in the same SOT-23-5 footprint, but verify pinout compatibility against the datasheet — the enable polarity and capacitor requirements may differ.
