Texas Instruments TLV70536YFMT

Overview

TLV70536YFMT from Texas Instruments is a 3.6-V fixed-output, 200-mA low-dropout (LDO) linear regulator in a 4-pin PicoStar™ package (0.77 mm × 0.77 mm, 0.15-mm max height), featuring 0.5% 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® modules.

For engineers reviewing the TLV70536YFMT datasheet, TLV70536YFMT pinout, TLV70536YFMT application, or TLV70536YFMT equivalent, key selection criteria include ultra-low profile packaging, stability with 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 TLV70536YFMT uses a PMOS pass transistor to achieve low dropout and maintains regulation down to 2 V input while delivering 3.6 V output. Its internal bandgap reference and error amplifier deliver ±0.5% DC accuracy across –40°C to +125°C and 0–200 mA load range.

It features active-high enable (EN) with 0.9 V turn-on threshold and 0.4 V shutdown threshold, enabling direct interface with low-voltage GPIOs. The device includes undervoltage lockout (UVLO), overcurrent limiting (typ. 400 mA), and thermal shutdown (160°C trip, 140°C reset), with no external pulldown required - distinguishing it from the TLV705P variant.

FAQ

What is the minimum input voltage required for TLV70536YFMT to maintain regulation at full 200-mA load?

The TLV70536YFMT requires a minimum input voltage of 3.745 V to sustain 3.6 V output at 200 mA, based on its 145-mV typical dropout voltage. At lower inputs, the device enters dropout mode and output drops linearly with VIN. This allows operation from partially discharged single-cell Li-ion batteries (≥3.7 V) without brownout.

Does TLV70536YFMT require an external pull-up resistor on the EN pin?

No, TLV70536YFMT does not require an external pull-up on EN. Its enable input draws only 0.01 μA and has a defined 0.9 V turn-on threshold and 0.4 V turn-off threshold. If always-on operation is desired, EN may be directly tied to VIN; for controlled sequencing, connect to a GPIO without additional biasing components.

Can TLV70536YFMT operate stably with a 0.22-μF X5R ceramic capacitor on VOUT?

Yes, TLV70536YFMT is stable with any ceramic capacitor ≥0.1 μF, including 0.22-μF X5R types. Its internal compensation eliminates need for ESR tuning, and the 0.22-μF value provides additional margin against bias/temperature derating - especially beneficial in high-temperature industrial deployments where capacitor effective capacitance may drop by >30%.

How does TLV70536YFMT handle reverse voltage conditions on VOUT?

TLV70536YFMT contains a PMOS pass transistor with an intrinsic body diode that conducts when VOUT exceeds VIN. This path is not current-limited, so sustained reverse voltage can cause damage. TI recommends limiting reverse current to ≤5% of rated output (≤10 mA) using an external Schottky diode or MOSFET-based reverse-polarity protection circuit upstream of VIN.

Is TLV70536YFMT pin-compatible with other devices in the TLV705 family?

Yes, TLV70536YFMT shares identical 4-pin PicoStar™ (YFM) pinout with all TLV705xYFM variants (e.g., TLV70512YFMT, TLV70528YFMT). Pin functions (VIN, GND, EN, VOUT) and physical layout are identical - enabling voltage-scaling flexibility across designs without PCB revision, provided input voltage and load requirements remain within spec.
