Texas Instruments TLV70534YFPR

Overview

TLV70534YFPR 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. It delivers 0.5% output accuracy, 145-mV dropout at 200 mA, 35-μA quiescent current, and 70-dB PSRR at 1 kHz-designed for powering RF-sensitive subsystems in space-constrained portable electronics.

For engineers reviewing the TLV70534YFPR datasheet, TLV70534YFPR pinout, TLV70534YFPR application, or TLV70534YFPR equivalent, key selection considerations include ultra-low profile packaging (0.15-mm max height), stability with only 0.1-μF ceramic output capacitance, enable-controlled shutdown with 1-μA quiescent current, and thermal/overcurrent protection for battery-powered systems.

Technical Context

The TLV70534YFPR uses a PMOS pass transistor architecture enabling low dropout and high PSRR with minimal VIN–VOUT headroom. Its error amplifier achieves ±0.5% 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 logic (VIH = 0.9 V, VIL = 0.4 V), and internal thermal shutdown (160°C trip, 140°C reset). The device operates stably with effective COUT ≥ 0.1 μF and requires no external compensation.

FAQ

What is the minimum input voltage required for TLV70534YFPR to maintain regulation at full 200-mA load?

The TLV70534YFPR requires VIN ≥ VOUT + VDO = 3.4 V + 0.145 V = 3.545 V to maintain regulation at 200 mA. Below this, the device enters dropout mode where VOUT tracks VIN minus dropout voltage. This headroom enables extended runtime in single-cell Li-ion systems discharging from 4.2 V down to ~3.55 V before regulation loss.

Can TLV70534YFPR operate with a 0.1-μF ceramic output capacitor, and why is this significant?

Yes, TLV70534YFPR is stable with an effective output capacitance as low as 0.1 μF-verified per TI SBVS151F datasheet Section 6.5. This eliminates need for larger, more expensive, or temperature-sensitive capacitors, reducing BOM cost and PCB area while improving reliability in thermally cycling environments like wearable electronics.

Does TLV70534YFPR include built-in protection features, and what are their thresholds?

Yes, TLV70534YFPR integrates thermal shutdown (160°C trip, 140°C reset), overcurrent limiting (~400 mA typical), and undervoltage lockout (1.9 V rising threshold). These functions operate autonomously without external components, protecting both the IC and downstream circuitry during fault conditions such as output shorts or excessive ambient temperature.

How does the enable pin (EN) of TLV70534YFPR behave, and what is its logic compatibility?

The EN pin of TLV70534YFPR is active-high with VIH = 0.9 V (min) and VIL = 0.4 V (max), making it compatible with 1.2-V, 1.8-V, and 3.3-V GPIOs without level shifters. When EN ≤ 0.4 V, the device enters shutdown drawing only 1 μA; when EN ≥ 0.9 V, regulation begins with 100-μs typical start-up time to 98% of 3.4 V.

Is TLV70534YFPR pin-compatible with other members of the TLV705 family, and what package options exist?

Yes, TLV70534YFPR shares identical 4-pin DSBGA (YFP) pinout with all TLV705xYFPR variants (e.g., TLV70512YFPR, TLV70528YFPR). It is also pin-compatible with the PicoStar (YFM) variant TLV70534YFMR. Both packages measure 0.77 mm × 0.77 mm but differ in height profile (YFP: 0.15-mm max; YFM: 0.25-mm max), allowing flexible mechanical design choices.
