Texas Instruments TLV70534YFPT

Overview

TLV70534YFPT from Texas Instruments is a 3.4-V fixed-output, 200-mA low-dropout (LDO) linear regulator in a 0.77-mm × 0.77-mm DSBGA package, featuring 0.5% typical output accuracy, 35-μA quiescent current, and 145-mV dropout at 200 mA - designed for power-sensitive RF and portable applications such as Bluetooth® and Zigbee® devices.

For engineers reviewing the TLV70534YFPT datasheet, TLV70534YFPT pinout, TLV70534YFPT application, or TLV70534YFPT equivalent, key selection considerations include ultra-low profile packaging, stability with only 0.1-μF ceramic output capacitance, high PSRR (70 dB at 1 kHz), thermal shutdown protection, and enable-controlled sequencing in space-constrained battery-powered systems.

Technical Context

The TLV70534YFPT uses a PMOS pass transistor to achieve low dropout and maintain regulation down to (VIN – VOUT) = 145 mV at full load. Its error amplifier delivers 0.5% typical DC accuracy across –40°C to +125°C and supports zero-load regulation.

It integrates undervoltage lockout (UVLO) triggering at 1.9 V, active-high enable with 0.9-V turn-on threshold, and thermal shutdown at 160°C. The device is stable with ≥0.1-μF effective ceramic output capacitance and achieves 70-dB PSRR at 1 kHz while consuming only 35 μA quiescent current.

FAQ

What is the minimum output capacitance required for stable operation of TLV70534YFPT?

TLV70534YFPT is stable with an effective output capacitance of only 0.1 μF ceramic - significantly lower than most LDOs requiring ≥1 μF. This enables use of small, low-cost, high-bias-voltage-rated capacitors and reduces PCB area. Ensure the capacitor has low ESR and is placed close to the VOUT and GND pins per TI layout guidelines.

Does TLV70534YFPT include thermal protection?

Yes, TLV70534YFPT integrates thermal shutdown protection that activates at 160°C junction temperature and resets at 140°C. This safeguards the device during sustained overload or poor PCB thermal dissipation. Combined with internal current limiting (260–550 mA), it provides robust fault handling without external components.

Can TLV70534YFPT be used with a 2.5-V input supply?

Yes, TLV70534YFPT supports input voltages from 2.0 V to 5.5 V. With a 2.5-V input, the dropout margin is 2.5 V – 3.4 V = –0.9 V - insufficient for regulation. Therefore, TLV70534YFPT requires VIN ≥ 3.545 V (3.4 V + 145 mV) to maintain regulation at 200 mA. For 2.5-V inputs, select a lower-output variant like TLV70525YFPT.

What is the enable pin threshold voltage for TLV70534YFPT?

The EN pin of TLV70534YFPT has a guaranteed turn-on threshold of ≥0.9 V and turn-off threshold of ≤0.4 V. This allows direct interfacing with low-voltage GPIOs (e.g., 1.8-V or 2.5-V I/O domains) without level-shifting. When EN is left unconnected or tied to VIN, TLV70534YFPT operates continuously.

How does TLV70534YFPT compare to the TLV705P series?

TLV70534YFPT belongs to the standard TLV705 series (not TLV705P). It lacks the active pulldown circuit found in TLV705P variants, meaning it cannot rapidly discharge VOUT when disabled. If fast output discharge is required, consider TLV70534YFMR (PicoStar, TLV705P variant) instead - but note it uses a different package and pinout.
