Product details
Overview
TPS72710DSET from Texas Instruments is a 1.0-V fixed-output, 250-mA ultralow-quiescent-current LDO linear regulator in a 1.5-mm × 1.5-mm WSON-6 package. It delivers 2% output accuracy over load, line, and temperature (–40°C to +125°C), features 7.9 μA ground current at zero load, 65 mV typical dropout at 100 mA, and supports stable operation with only a 1.0-μF ceramic output capacitor - ideal for battery-powered RF subsystems in smartphones and wireless sensors.
For engineers reviewing the TPS72710DSET datasheet, TPS72710DSET pinout, TPS72710DSET application, or TPS72710DSET equivalent, key selection criteria include its ultralow IQ for multi-week standby, fast ±50 mV load transient response under 200 mA step changes, high PSRR (70 dB @ 1 kHz), and factory-programmed 1.0-V output eliminating external feedback components.
Technical Context
The TPS72710DSET uses a PMOS pass transistor architecture enabling low dropout and rail-to-rail input compatibility down to 2.0 V. Its internal EEPROM-programmed reference ensures precise 1.0-V output without external resistors, while the band-gap error amplifier maintains 2% regulation across –40°C to +125°C junction temperature.
Functional modes are controlled via an active-high EN pin (0.9 V threshold), delivering 120 nA shutdown current. Protection includes thermal shutdown (trip at +160°C, reset at +140°C) and current limiting (typ. 400 mA), with undervoltage lockout activating below 1.85 V input.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 1.0 V ±2% over full load/line/temp range - eliminates external resistor network and layout sensitivity. |
| Max output current | 250 mA continuous - sufficient for RF transceivers, MCU cores, and sensor signal chains in portable devices. |
| Quiescent current | 7.9 μA at IOUT = 0 mA - enables >1-year battery life in always-on IoT endpoints with 200-mAh coin cells. |
| Dropout voltage | 65 mV typ. at 100 mA - allows operation from 1.1 V input, critical for single-cell Li-ion or Li-poly systems near end-of-discharge. |
| PSRR | 70 dB at 1 kHz - suppresses switching noise from DC/DC converters feeding the LDO input, preserving RF receiver SNR. |
| Load transient response | ±50 mV for 200 mA load step - maintains stable bias for sensitive analog circuits without requiring oversized output capacitance. |
| Stability | Guaranteed with ≥1.0-μF X5R/X7R ceramic COUT - reduces BOM count and PCB area vs. tantalum or aluminum electrolytic solutions. |
Pinout & Package
TPS72710DSET is housed in a thermally enhanced 1.5-mm × 1.5-mm WSON-6 (DSE) package with exposed thermal pad (not electrically connected). The 6-pin configuration supports compact two-layer layouts and provides dedicated GND and NC pins for thermal optimization.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output | Delivers stable 1.0 V; requires 1.0-μF ceramic capacitor to GND for stability and transient performance. |
| 2 (NC) | No connection | Internally unconnected; may be tied to GND on PCB to improve thermal dissipation without electrical impact. |
| 3 (GND) | Ground reference | Primary return path for load and quiescent current; must be low-impedance to minimize ground bounce during transients. |
| 4 (EN) | Enable control | Active-high logic input; drives regulator ON above 0.9 V, OFF below 0.4 V - enables system-level power sequencing. |
| 5 (NC) | No connection | Internally unconnected; same thermal role as Pin 2 - recommended to connect to GND plane for heatsinking. |
| 6 (IN) | Input supply | Accepts 2.0 V to 5.5 V; requires local 0.1–1.0-μF ceramic bypass capacitor to suppress high-frequency noise and source impedance. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-programmed 1.0-V output | Eliminates external feedback resistors and associated layout parasitics, reducing design cycle time and calibration risk. |
| Ultralow 7.9 μA quiescent current | Extends battery runtime in always-on applications such as BLE beacons and wearable health monitors without sacrificing regulation accuracy. |
| 65 mV dropout at 100 mA | Enables direct regulation from partially discharged single-cell batteries (e.g., 1.1 V minimum input), maximizing usable energy. |
| 70 dB PSRR at 1 kHz | Mitigates ripple from upstream switching regulators, preventing degradation of ADC reference stability or RF synthesizer phase noise. |
| Stable with 1.0-μF ceramic output cap | Reduces solution size and cost versus traditional LDOs requiring ≥10-μF tantalum capacitors, while improving reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS72710YFFR | Same 1.0-V output and specs, but in 0.4-mm pitch DSBGA-4 (1.2 mm × 0.8 mm) - 2 mm² smaller footprint, no NC pins. | Better suited for ultra-dense wearables where board area is constrained; thermal resistance higher (RθJA = 160°C/W vs. 190.5°C/W). | Select YFFR for space-constrained designs accepting slightly reduced thermal margin; DSE preferred when thermal performance or solder joint reliability is critical. |
| TPS7A0510PDBVR | 1.0-V fixed LDO with 1-μA IQ, 250-mA rating, but larger SOT-23-5 package; lacks EEPROM programming and has 170 mV dropout at 100 mA. | Lower cost alternative for non-battery-critical applications; not suitable for <1.2-V input or RF-sensitive designs due to lower PSRR (55 dB @ 1 kHz). | Choose PDBVR only if board area and thermal constraints are relaxed and ultra-low dropout is not required; DSE remains optimal for portable RF systems. |
Compared with TPS72710YFFR, the TPS72710DSET offers superior thermal performance and simplified layout with accessible NC pins for grounding, while TPS7A0510PDBVR trades off dropout and noise performance for cost and legacy package compatibility.

FAQ
What is the guaranteed output voltage accuracy of the TPS72710DSET across operating conditions?
The TPS72710DSET guarantees ±2.0% output voltage accuracy over the full operating range: load current 0–250 mA, input voltage 2.0–5.5 V, and junction temperature –40°C to +125°C. This specification is confirmed in the Electrical Characteristics table of the official datasheet (SBVS128F, Rev F), and applies directly to the TPS72710DSET variant with factory-programmed 1.0-V output.
Does the TPS72710DSET require an input capacitor for stability?
The TPS72710DSET 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 to improve transient response, reduce noise coupling, and suppress source impedance effects. This guidance is specified in Section 8.2.1.1 of the TPS727 datasheet and applies identically to the TPS72710DSET.
Can the TPS72710DSET operate with an input voltage below 2.0 V?
No - the absolute maximum ratings specify a minimum input voltage of –0.3 V, but the Recommended Operating Conditions define a functional minimum VIN of 2.0 V. Below 2.0 V, the TPS72710DSET may fail to regulate or activate undervoltage lockout (UVLO threshold is 1.85–1.95 V), and dropout behavior becomes undefined. Operation below 2.0 V is outside specification and not supported for the TPS72710DSET.
How does the TPS72710DSET behave during startup when the EN pin is asserted?
Upon EN assertion (rising above 0.9 V), the TPS72710DSET achieves 98% of its 1.0-V output within 100 μs (typical startup time), as measured with COUT = 1.0 μF and load currents up to 250 mA. This parameter is explicitly characterized in the Electrical Characteristics table and applies to the TPS72710DSET under all valid operating conditions.
Is the TPS72710DSET compatible with ceramic output capacitors having ESR below 1 mΩ?
Yes - the TPS72710DSET is explicitly characterized and guaranteed stable with standard X5R/X7R ceramic capacitors ≥1.0 μF and ESR < 200 mΩ. Ultra-low-ESR MLCCs (e.g., <1 mΩ) are fully compatible and do not induce oscillation; TI's stability analysis confirms unconditional stability across the specified capacitor range for the TPS72710DSET.
