Texas Instruments TLV70536YFPR

Overview

TLV70536YFPR from Texas Instruments is a 3.6-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, 35-μA quiescent current, 145-mV dropout at 200 mA, and 70-dB PSRR at 1 kHz - optimized for Li-ion–powered handheld devices requiring stable, low-noise biasing of RF and digital circuitry.

For engineers reviewing the TLV70536YFPR datasheet, TLV70536YFPR pinout, TLV70536YFPR application, or TLV70536YFPR equivalent, key selection criteria include ultra-small footprint compatibility, sub-1-μF ceramic capacitor stability, enable-controlled power sequencing, thermal shutdown behavior, and performance under low VIN–VOUT headroom conditions.

Technical Context

The TLV70536YFPR uses a PMOS pass transistor architecture enabling low dropout and high PSRR with minimal input-to-output voltage margin. Its internal bandgap reference and error amplifier deliver ±0.5% DC accuracy across –40°C to +125°C and full load range (0–200 mA).

It features active-high enable logic (EN threshold: 0.9 V), undervoltage lockout (UVLO at 1.9 V), and integrated thermal shutdown (trip at 160°C). The device remains stable with ≥0.1-μF effective output capacitance and regulates accurately even at zero load.

FAQ

What is the minimum input voltage required for TLV70536YFPR to maintain regulation at full 200-mA load?

The TLV70536YFPR requires a minimum input voltage of 3.745 V to maintain 3.6-V regulation at 200 mA, based on its specified 145-mV dropout voltage. Below this, the output drops linearly with input. This headroom enables reliable operation across the discharge curve of a single-cell Li-ion battery (3.0–4.2 V), supporting >85% of usable battery capacity.

Can TLV70536YFPR operate stably with a 0.22-μF X7R ceramic capacitor on the output?

Yes, TLV70536YFPR is stable with any ceramic capacitor ≥0.1 μF, including 0.22-μF X7R types. Its internal compensation eliminates need for ESR-based damping, allowing use of small, high-bias-stability capacitors. TI recommends placing the capacitor within 2 mm of VOUT and GND pins with direct plane connections to ensure optimal transient response and noise rejection.

Does TLV70536YFPR include reverse-voltage protection?

No, TLV70536YFPR does not integrate reverse-voltage protection. Its PMOS pass transistor includes a body diode that conducts if VOUT exceeds VIN, potentially causing uncontrolled current flow. For applications with possible reverse bias (e.g., hot-swap, dual-supply systems), TI recommends adding an external Schottky diode in series with VIN or using a dedicated reverse-protection IC upstream of TLV70536YFPR.

How does the enable pin (EN) of TLV70536YFPR behave during power-up sequences?

The EN pin of TLV70536YFPR has a 0.9-V turn-on threshold and 0.4-V turn-off threshold, with leakage <0.01 μA. When driven by a microcontroller GPIO, it enables fast, controlled power sequencing - e.g., asserting EN only after main system rail reaches 2.5 V. If left unconnected, internal pull-down ensures default OFF state, preventing unintended startup.

Is TLV70536YFPR suitable for powering RF transceivers requiring ultra-low phase noise?

Yes, TLV70536YFPR is well-suited for RF transceivers due to its 26.6 μV_RMS integrated output noise (100 Hz–100 kHz) and 70-dB PSRR at 1 kHz. These specs directly reduce supply-induced phase noise in VCOs and improve EVM in QAM-modulated signals. For best results, pair with localized 0.1-μF + 1-μF ceramic decoupling and avoid shared ground paths with digital switching noise sources.
