Product details
Overview
TPS72730YFFT from Texas Instruments is a 3.0-V fixed-output, 250-mA ultralow-IQ LDO linear regulator in a 4-ball DSBGA (1.20 mm × 0.80 mm) package, featuring 7.9 μA quiescent current, 65 mV typical dropout at 100 mA, ±2% output accuracy over load/line/temperature, and stable operation with only a 1.0-μF ceramic output capacitor. It serves as a precision voltage source for RF-sensitive, battery-powered subsystems such as Bluetooth transceivers and sensor signal chains.
For engineers reviewing the TPS72730YFFT datasheet, TPS72730YFFT pinout, TPS72730YFFT application, or TPS72730YFFT equivalent, this page delivers verified electrical specs, thermal performance data, EN-controlled shutdown behavior, ground current vs. temperature curves, PSRR vs. frequency plots, and validated design guidance for handheld and wireless embedded systems.
Technical Context
The TPS72730YFFT employs a PMOS pass transistor architecture enabling low dropout and inherent reverse-voltage blocking via its integrated body diode. Its factory-programmed EEPROM sets the 3.0-V output without external resistors, while a precision band-gap reference and error amplifier ensure ±2% DC accuracy across –40°C to +125°C.
It delivers ultrafast load transient response (±50 mV for 200-mA step) due to high-loop bandwidth and internal compensation optimized for 1.0-μF ceramic capacitors. PSRR reaches 70 dB at 1 kHz and remains >40 dB up to 1 MHz, supporting noise-critical RF and ADC supply domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V, factory-programmed via EEPROM - eliminates external feedback network and ensures production consistency. |
| Max Output Current | 250 mA - supports moderate-power RF ICs and microcontrollers without external current boosting. |
| Quiescent Current | 7.9 μA - enables multi-year battery life in always-on IoT sensors and remote controls. |
| Dropout Voltage | 65 mV @ 100 mA - allows operation from 3.065 V input, critical for single-cell Li-ion or Li-poly systems near end-of-discharge. |
| PSRR | 70 dB @ 1 kHz - suppresses switching noise from adjacent DC/DC converters feeding mixed-signal SoCs. |
| Ground Pin Current | 110 μA @ 200 mA - enables accurate power budgeting and thermal modeling in compact layouts. |
| Startup Time | 100 μs - meets fast wake-up requirements for BLE beacon and UWB ranging subsystems. |
| Thermal Shutdown | Triggers at +160°C, resets at +140°C - provides fail-safe protection during sustained overload or poor PCB thermal relief. |
Pinout & Package
TPS72730YFFT uses a 4-ball, 0.4-mm pitch wafer-level chip-scale package (DSBGA-4), measuring 1.20 mm × 0.80 mm with bottom-side solder balls. The package lacks an exposed thermal pad and relies on board-level copper for heat dissipation (RθJB = 76°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | EN (Enable) | Active-high digital control: ≥0.9 V enables regulation; ≤0.4 V reduces ground current to 120 nA for ultra-low-power sleep mode. |
| A2 | IN | Main input supply connection - requires ≥2.0 V; supports up to 5.5 V; UVLO engages below 1.85 V. |
| B1 | GND | Power ground reference - carries total input current minus load current; measured ground pin current includes quiescent and load-dependent components. |
| B2 | OUT | Regulated 3.0-V output - stable with ≥1.0-μF X5R/X7R ceramic capacitor; ESR < 200 mΩ required. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow IQ | 7.9 μA quiescent current - minimizes standby power loss in battery-backed real-time clocks and memory retention circuits. |
| Fast Load Transient | ±50 mV deviation for 200-mA load step - maintains clean supply for RF transceivers during TX burst without external compensation. |
| No Noise Reduction Pin | Low 33.5 μVRMS output noise (100 Hz–100 kHz) - eliminates need for external bypass capacitors in analog front-end power rails. |
| Factory-Programmed Output | 3.0-V output set permanently in EEPROM - removes resistor tolerance errors and layout sensitivity of adjustable LDOs. |
| Thermal & Current Protection | Integrated thermal shutdown (+160°C trip) and current limit (~400 mA typical) - prevents damage during short-circuit or PCB trace overheating. |
| Small-Signal Stability | Stable with 1.0-μF ceramic output capacitor - simplifies BOM and layout for space-constrained wearables and hearing aids. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS72733YFFT | Fixed 3.3-V output; identical package, pinout, and spec sheet except output voltage and associated dropout/accuracy test conditions. | Requires system-level validation if downstream logic or ADC references depend on exact 3.0-V level. | Select when 3.3-V rail is needed for I/O compatibility with 3.3-V peripherals; no layout change required. |
| MCP1703T-3002E/MB | 3.0-V fixed LDO in SOT-23-5; 2.5-μA IQ, 600-mA output, but larger package (2.9 mm × 1.6 mm) and requires 2.2-μF output capacitor. | Higher current capability suits higher-power sensors but increases board area and may degrade PSRR above 100 kHz. | Choose for cost-sensitive industrial sensors where size is secondary and >250 mA peak current is needed. |
Compared with TPS72730YFFT, TPS72733YFFT offers identical form-factor and performance at 3.3 V, while MCP1703T-3002E/MB trades ultra-small size and RF-grade PSRR for higher output current and lower quiescent current in a legacy package.

FAQ
What is the maximum input voltage rating for the TPS72730YFFT?
The TPS72730YFFT has an absolute maximum input voltage of +6.0 V, but its recommended operating range is 2.0 V to 5.5 V. Operation above 5.5 V risks permanent damage, and UVLO activates below 1.85 V to prevent unstable regulation. For reliable 3.0-V output, VIN must exceed 3.065 V to maintain dropout margin at full load.
Does the TPS72730YFFT require an input capacitor for stability?
The TPS72730YFFT does not require an input capacitor for basic stability, but TI recommends a 0.1-μF to 1.0-μF low-ESR ceramic capacitor between IN and GND to improve transient response, reduce ripple, and counteract reactive source impedance. This is especially critical when the device is located far from the power source or supplies fast-switching loads like RF transceivers.
How does the enable (EN) pin function on the TPS72730YFFT?
The EN pin on the TPS72730YFFT is active-high: driving it to ≥0.9 V enables regulation, while pulling it ≤0.4 V places the device in shutdown mode with ground current reduced to 120 nA nominal. If shutdown is unused, EN may be tied directly to IN. The pin draws only 40–500 nA, making it compatible with weak GPIOs or open-drain logic.
Can the TPS72730YFFT be used with a 0.47-μF output capacitor?
No-the TPS72730YFFT is specified and characterized for stability only with ≥1.0-μF ceramic output capacitance (X5R/X7R dielectric). Using 0.47 μF violates the minimum requirement and may cause oscillation or excessive overshoot during load transients. TI's datasheet explicitly states "stable with a 1.0-μF ceramic capacitor" and defines ESR limits accordingly.
What is the thermal resistance (RθJB) of the TPS72730YFFT in its YFF package?
The TPS72730YFFT in the DSBGA-4 (YFF) package has a junction-to-board thermal resistance (RθJB) of 76°C/W, per TI's SBVS128F datasheet Section 6.4. This value assumes standard JEDEC 2-layer board construction and reflects heat transfer through solder balls into the PCB copper. It is significantly lower than the WSON-6 variant (149.3°C/W), confirming the YFF package's superior board-level thermal performance.
