Texas Instruments TPS72750YFFR

Overview

TPS72750YFFR from Texas Instruments is a 5.0-V fixed-output, 250-mA ultralow-I_Q LDO linear regulator in a 4-ball DSBGA (1.20 mm × 0.80 mm) package, featuring 65 mV typical dropout at 100 mA, 7.9 μA quiescent current, and ±50 mV load transient response for 200 mA step changes - deployed in RF-sensitive portable power rails such as Bluetooth® baseband supplies.

For engineers reviewing the TPS72750YFFR datasheet, TPS72750YFFR pinout, TPS72750YFFR application, or TPS72750YFFR equivalent, key selection criteria include dropout voltage under 200 mA load, PSRR >70 dB at 1 kHz, thermal shutdown at +160°C, ground current <130 μA at full load, and compatibility with 1.0-μF ceramic output capacitance without external compensation.

Technical Context

The TPS72750YFFR uses a PMOS pass transistor architecture enabling low dropout and inherent reverse-voltage blocking via its body diode. Its factory-programmed EEPROM sets the 5.0-V output precisely, eliminating external feedback resistors and ensuring 2% DC accuracy across –40°C to +125°C.

It integrates active soft-start (0.07 V/μs ramp rate), undervoltage lockout (1.90 V nominal threshold), and thermal cycling protection (+160°C trip / +140°C recovery). Shutdown current is 120 nA, and PSRR remains ≥40 dB up to 100 kHz despite ultralow I_Q.

Key Specifications

Pinout & Package

TPS72750YFFR is housed in a 4-ball, 0.4-mm pitch wafer-level chip-scale package (DSBGA-4), measuring 1.20 mm × 0.80 mm with ball A1 marked by GND (for 5.0-V variant per TI package note). The package has no thermal pad and relies on board-level copper for heat dissipation (R_θJB = 76°C/W).

FAQ

What is the maximum input voltage rating for the TPS72750YFFR?

The TPS72750YFFR has an absolute maximum input voltage of +6.0 V. Operation beyond this risks permanent damage. For reliable continuous use, TI specifies 2.0 V to 5.5 V as the recommended input range - sufficient to maintain 5.0 V output with margin above the 65 mV dropout at 100 mA. Exceeding 5.5 V may trigger internal UVLO or overstress internal circuitry.

Does the TPS72750YFFR require an input capacitor for stability?

The TPS72750YFFR does not require an input capacitor for basic stability, but TI strongly recommends a 0.1–1.0 μF ceramic capacitor between IN and GND. This improves transient response, reduces ripple from upstream sources, and mitigates reactive impedance effects - especially critical in battery-powered or DC/DC-fed systems where source impedance varies. Omitting it may degrade PSRR and load-step performance.

How does the enable pin (EN) function on the TPS72750YFFR?

The EN pin on the TPS72750YFFR is active-high: driving it above 0.9 V enables regulation, while pulling it below 0.4 V places the device in shutdown mode with ground current reduced to 120 nA. When unused, EN may be tied to IN. Unlike open-drain enable inputs, this pin draws only 40–500 nA, making it compatible with weak microcontroller GPIOs without additional level-shifting.

Can the TPS72750YFFR be used with a 2.2-μF output capacitor?

Yes - the TPS72750YFFR is stable with output capacitances ≥1.0 μF, including 2.2 μF ceramic types (X5R/X7R). Larger values reduce transient overshoot magnitude but increase recovery time. TI confirms stability up to 10 μF; however, soft-start current scales with C_OUT, and values >10 μF may cause current limiting during startup unless load current is very low.

What thermal derating applies to the TPS72750YFFR at 250 mA output?

At 250 mA output and 5.5 V input, power dissipation is ~125 mW. With R_θJB = 76°C/W, junction-to-board temperature rise is ~9.5°C above ambient. To stay within the +125°C max operating junction temperature, ambient must remain ≤115.5°C - but TI recommends limiting continuous operation to ≤+85°C ambient for reliability. Thermal shutdown activates at +160°C, providing safety margin.
