Texas Instruments TLV70530YFMR

Overview

TLV70530YFMR 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, featuring 0.5% output accuracy, 35-μA quiescent current, and 145-mV dropout at 200 mA - designed for power-sensitive RF and portable applications including Bluetooth® and Zigbee® devices.

For engineers reviewing the TLV70530YFMR datasheet, TLV70530YFMR pinout, TLV70530YFMR application, or TLV70530YFMR equivalent, key selection considerations include ultra-low profile packaging (0.15-mm max height), 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 TLV70530YFMR employs a PMOS pass transistor architecture enabling low dropout voltage and high PSRR even with minimal VIN–VOUT headroom. Its internal bandgap reference and error amplifier deliver 0.5% typical DC accuracy across –40°C to +125°C and 0–200 mA load range.

It integrates active-high enable logic (VIH = 0.9 V, VIL = 0.4 V), undervoltage lockout (1.9 V), thermal shutdown (160°C trip), and overcurrent protection (typical 400-mA limit). The device operates stably with ≥0.1-μF ceramic COUT and requires no external compensation.

FAQ

What is the minimum output capacitance required for stable operation of TLV70530YFMR?

The TLV70530YFMR is specified to operate stably with an effective output capacitance of only 0.1 μF - typically a 0.1-μF X7R ceramic capacitor placed directly at the VOUT pin. This low requirement reduces PCB area and BOM cost compared to LDOs needing ≥1-μF output capacitors. Larger values improve PSRR and transient response but are not mandatory for stability.

Does TLV70530YFMR support enable-controlled power sequencing in multi-rail systems?

Yes, TLV70530YFMR features an active-high EN pin with VIH = 0.9 V (min) and VIL = 0.4 V (max), allowing direct interfacing with modern low-voltage GPIOs. When disabled, ground pin current drops to 1 μA (typ), enabling precise sequencing and zero-load shutdown. The EN pin can be tied to VIN if enable functionality is not needed.

What is the dropout voltage of TLV70530YFMR at full 200-mA load?

The dropout voltage of TLV70530YFMR is 145 mV at IOUT = 200 mA and TJ = 25°C, per the Electrical Characteristics table. This means the device maintains regulation as long as VIN ≥ 3.145 V. Dropout increases slightly with temperature and decreases at lighter loads - e.g., 105 mV at 150 mA - enabling extended battery runtime in portable applications.

How does TLV70530YFMR handle reverse voltage conditions on the VOUT pin?

TLV70530YFMR contains a PMOS pass transistor with an intrinsic body diode that conducts when VOUT exceeds VIN. This path is not current-limited, so TI recommends external protection (e.g., series Schottky diode or MOSFET-based reverse-blocking circuit) if sustained reverse voltage >5% of rated output current is expected - especially in systems with multiple power domains or hot-swap scenarios.

Is TLV70530YFMR compatible with standard 0.4-mm pitch solder reflow profiles?

Yes, TLV70530YFMR in the YFM (PicoStar™) package is qualified for standard lead-free reflow per JEDEC J-STD-020. Its 0.77-mm × 0.77-mm footprint and 0.4-mm ball pitch align with common fine-pitch SMT processes. Thermal resistance data (RθJA = 191.7°C/W) confirms suitability for typical handheld PCB stack-ups with single-layer thermal relief.
