Product details
Overview
TPS72711YFFT from Texas Instruments is a 1.1-V fixed-output, 250-mA ultralow-IQ LDO linear regulator in a 4-ball DSBGA package (1.20 mm × 0.80 mm), 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 TPS72711YFFT datasheet, TPS72711YFFT pinout, TPS72711YFFT application, or TPS72711YFFT equivalent, key selection criteria include its factory-programmed 1.1-V output, thermal shutdown at +160°C, PSRR of 70 dB at 1 kHz, stability with 1.0-µF ceramic output capacitance, and compatibility with 0.4-mm pitch wafer-level packaging for space-constrained handheld designs.
Technical Context
The TPS72711YFFT uses a PMOS pass transistor to achieve low dropout and integrates factory EEPROM programming for precise 1.1-V output voltage without external resistors. Its internal bandgap reference and error amplifier deliver 2% DC accuracy across –40°C to +125°C, load (0–250 mA), and line (2.0–5.5 V) variations.
It features active-high enable logic with 0.9 V turn-on threshold and 0.4 V shutdown threshold, 120 nA shutdown current, undervoltage lockout at 1.90 V (typ), and thermal cycling between +140°C (restart) and +160°C (shutdown). Ground pin current remains ≤130 µA at 250 mA load and full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.1 V ±2% over load, line, and temperature - eliminates external feedback network and ensures stable core voltage for low-power MCUs. |
| Max Output Current | 250 mA continuous - supports single-rail powering of RF transceivers or sensor hubs without derating at +85°C ambient. |
| Dropout Voltage | 65 mV (typ) at 100 mA - enables operation from 1.165 V input, critical for battery-powered systems near end-of-life. |
| Quiescent Current | 7.9 µA (typ) - extends battery life in always-on wake-up circuits, e.g., BLE beacon standby mode. |
| PSRR @ 1 kHz | 70 dB - suppresses switching noise from adjacent DC/DC converters feeding noisy system rails. |
| Load Transient Response | ±50 mV for 200 mA step (1 µs edge) - maintains clean supply during burst-mode RF transmission without external compensation. |
| Stability Capacitor | 1.0 µF ceramic (X5R/X7R) - enables compact layout with no ESR requirements, reducing BOM count vs. older LDOs. |
| Operating Temp Range | –40°C to +125°C junction - qualified for automotive infotainment SoC I/O rail and industrial handheld environments. |
Pinout & Package
TPS72711YFFT is housed in a 4-ball, 0.4-mm pitch DSBGA (DSBGA-4) package measuring 1.20 mm × 0.80 mm, with ball A1 marked by GND (per TI SBVS128F Rev F, p.4 note).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (A2) | Input voltage supply | Accepts 2.0–5.5 V input; requires local 0.1–1.0 µF ceramic decoupling to suppress source impedance effects. |
| EN (A1) | Enable control input | Active-high logic: ≥0.9 V enables regulation; ≤0.4 V disables output and reduces ground current to 120 nA. |
| GND (B1) | Ground reference | Primary return path for load, bias, and protection circuitry; marked with top-side dot on 1.1-V YFF variants. |
| OUT (B2) | Regulated output | Delivers 1.1 V ±2%; must be bypassed with ≥1.0 µF X5R/X7R ceramic capacitor directly at pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Factory EEPROM-programmed output | 1.1 V preset at wafer level - eliminates external resistor divider, saves PCB area, and guarantees initial accuracy without calibration. |
| Ultralow ground pin current | ≤130 µA at 250 mA and +125°C - minimizes total system current draw in battery-critical applications like remote sensors. |
| RF-optimized PSRR | 70 dB at 1 kHz, 45 dB at 1 MHz - rejects noise from high-frequency switching regulators sharing same battery source. |
| Thermal and current protection | +160°C shutdown / +140°C restart + 400 mA current limit - prevents damage during short-circuit or overload without external circuitry. |
| Fast startup time | 100 µs to 98% of 1.1 V - meets timing requirements for rapid wake-from-sleep sequences in portable devices. |
| No noise-reduction pin required | 33.5 µVRMS output noise (100 Hz–100 kHz) - supports noise-sensitive analog/RF blocks without additional filtering components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS72712YFFT | Fixed 1.2-V output (vs. 1.1 V); identical package, specs, and feature set. | Used where system SoC requires 1.2-V I/O or core voltage instead of 1.1 V. | Select when target voltage matches 1.2 V; pinout, layout, and thermal behavior are identical. |
| MCP1703T-1102E/MB | 1.1-V fixed output, SOT-23-5 package, 2.5-µA IQ, but only 250 mA peak and 60 dB PSRR @ 1 kHz. | Suitable for cost-sensitive, non-RF applications where lower PSRR and larger footprint are acceptable. | Choose for simpler designs without stringent RF noise rejection; not drop-in due to different pinout and thermal performance. |
Compared with TPS72711YFFT, TPS72712YFFT offers identical performance at 1.2 V and enables direct layout reuse, while MCP1703T-1102E/MB trades RF-grade PSRR and wafer-level miniaturization for lower cost and quiescent current in less demanding environments.

FAQ
What is the exact output voltage tolerance of the TPS72711YFFT over temperature and load?
The TPS72711YFFT delivers 1.1 V with ±2.0% DC accuracy across the full operating range: –40°C to +125°C junction temperature, 0–250 mA load current, and 2.0–5.5 V input voltage. This specification is guaranteed per TI SBVS128F Rev F Section 6.5, and includes initial factory EEPROM trim plus drift compensation from the precision bandgap and error amplifier.
Can the TPS72711YFFT operate with an input voltage below 2.0 V?
No - the TPS72711YFFT has a minimum recommended input voltage of 2.0 V per Section 6.3 of the datasheet. At 1.1 V output, the absolute minimum input is defined by dropout: VIN ≥ VOUT + VDO = 1.1 V + 65 mV = 1.165 V, but the device is not characterized or guaranteed below 2.0 V input due to UVLO activation (1.90 V typ) and degraded PSRR/transient performance.
Does the TPS72711YFFT require an input capacitor for stability?
An input capacitor is not required for stability per TI SBVS128F Section 8.2.1.1, but a 0.1–1.0 µF ceramic capacitor is strongly recommended between IN and GND to improve transient response, reduce noise coupling, and counteract source impedance - especially when the device is distant from the power source or shares a rail with switching regulators.
What is the thermal shutdown behavior of the TPS72711YFFT during sustained overload?
The TPS72711YFFT activates thermal shutdown at +160°C (typ) junction temperature and restarts at +140°C (typ), causing controlled on/off cycling under sustained overload. This protects against permanent damage but degrades reliability if continuously triggered; design must ensure worst-case junction temperature stays ≤+125°C using layout, board copper, and ambient derating per Section 7.3.6.
Is the TPS72711YFFT pin-compatible with other members of the TPS727xxYFF family?
Yes - all TPS727xxYFF variants (e.g., TPS72712YFFT, TPS72715YFFT) share identical DSBGA-4 pinout, package dimensions (1.20 mm × 0.80 mm), and ball assignment (IN/A2, EN/A1, GND/B1, OUT/B2). Only the factory-programmed output voltage differs; no PCB or layout change is needed when swapping within the YFF series.
