Texas Instruments TLV70530YFMT

Overview

TLV70530YFMT from Texas Instruments is a 3.0-V fixed-output, 200-mA low-dropout (LDO) linear regulator in a 0.77-mm × 0.77-mm PicoStar™ package. It delivers 0.5% output accuracy, 35-μA quiescent current, and 145-mV dropout at 200 mA - optimized for Li-ion–powered handheld devices requiring ultra-low profile and high PSRR.

For engineers reviewing the TLV70530YFMT datasheet, TLV70530YFMT pinout, TLV70530YFMT application, or TLV70530YFMT equivalent, key selection criteria include its 0.1-μF minimum stable output capacitance, active-high enable with 0.9-V turn-on threshold, thermal shutdown protection, and compatibility with ceramic capacitors in space-constrained RF subsystems.

Technical Context

The TLV70530YFMT uses a PMOS pass transistor to achieve low dropout and maintain regulation down to 2 V input while delivering 3.0 V output. Its internal bandgap reference and error amplifier ensure ±0.5% DC accuracy across –40°C to +125°C and 0–200 mA load range.

It features an active-high enable pin with 0.9-V logic threshold, supports 100-Hz–100-kHz integrated output noise of 28.2 μV_RMS (at 3.3-V_IN/3.0-V_OUT), and achieves 70 dB PSRR at 1 kHz - critical for noise-sensitive RF and audio rails in portable electronics.

FAQ

What is the minimum input voltage required for TLV70530YFMT to regulate 3.0 V at 200 mA?

The TLV70530YFMT requires a minimum input voltage of 3.145 V to maintain regulation at 200 mA, based on its specified 145-mV dropout voltage. Below this, the device enters dropout mode and output voltage tracks VIN minus VDO. This value is confirmed across –40°C to +125°C per Electrical Characteristics table in the SBVS151F datasheet.

Can TLV70530YFMT operate with a 0.1-μF output capacitor, and what type is recommended?

Yes, TLV70530YFMT is stable with a minimum 0.1-μF ceramic output capacitor - explicitly validated in the datasheet's "Stable With Effective Capacitance of 0.1 μF" feature and Electrical Characteristics. X5R or X7R dielectrics are recommended for stable capacitance across voltage and temperature; aluminum or tantalum capacitors are not required or recommended.

Does TLV70530YFMT include thermal protection, and at what junction temperature does it activate?

Yes, TLV70530YFMT integrates thermal shutdown protection that activates at 160°C junction temperature (rising) and resets at 140°C (falling), as specified in the Electrical Characteristics table. This auto-recovery feature prevents permanent damage during sustained overload or poor PCB thermal design, and applies uniformly across all TLV705 variants including TLV70530YFMT.

What is the enable pin behavior of TLV70530YFMT, and can it be tied directly to VIN?

The EN pin of TLV70530YFMT is active-high with a 0.9-V turn-on threshold and 0.4-V turn-off threshold. It draws only 0.01 μA at 5.5 V, so connecting EN directly to VIN is fully supported and commonly used when enable control is unnecessary - ensuring reliable startup without additional logic or pull-up resistors.

How does TLV70530YFMT compare to the TLV705P series in terms of output discharge capability?

TLV70530YFMT belongs to the standard TLV705 series and does not include active pulldown circuitry. Unlike the TLV705P variant (e.g., TLV70530PDBVR), it relies on natural load discharge and has no dedicated output discharge path. Therefore, TLV70530YFMT should not be selected where rapid VOUT discharge is required - that function is exclusive to TLV705P part numbers.
