Product details
Overview
TPS72727DSET from Texas Instruments is a 2.7-V fixed-output, 250-mA ultralow-IQ LDO linear regulator with 65 mV typical dropout at 100 mA, 7.9 μA quiescent current, and ±50 mV load transient response for 200 mA step changes-designed for RF-sensitive portable power rails in Bluetooth® and Zigbee® modules.
For engineers reviewing the TPS72727DSET datasheet, TPS72727DSET pinout, TPS72727DSET application, or TPS72727DSET equivalent, key selection criteria include dropout voltage at 200 mA, PSRR at 1 kHz (70 dB), ground current vs temperature behavior, and compatibility with 1.0-μF ceramic output capacitors without external compensation.
Technical Context
The TPS72727DSET uses a PMOS pass transistor architecture enabling low dropout and inherent reverse-voltage blocking via its body diode. Its factory-programmed EEPROM sets the 2.7-V output without external resistors, while a precision band-gap reference and error amplifier maintain 2% total DC accuracy across –40°C to +125°C.
It integrates active high EN control with 0.9 V turn-on threshold, thermal shutdown at +160°C, current limiting (~400 mA typical), and undervoltage lockout at 1.90 V (rising). Startup time is 100 μs with 1.0-μF COUT, and soft-start current scales linearly with COUT and load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.7 V, factory-programmed via EEPROM-no external feedback required. |
| Max Output Current | 250 mA continuous; internal current limit clamps at ~400 mA to protect pass device. |
| Quiescent Current | 7.9 μA typical at IOUT = 0 mA-enables multi-year battery life in always-on sensors. |
| Dropout Voltage | 130 mV typical at 200 mA-supports operation with minimal VIN–VOUT headroom. |
| PSRR @ 1 kHz | 70 dB-rejects switching noise from upstream DC/DC converters in RF subsystems. |
| Load Transient | ±50 mV for 200 mA load step-maintains stable rail during burst-mode wireless transmission. |
| Thermal Shutdown | Triggers at +160°C junction; auto-restarts at +140°C-prevents permanent damage under overload. |
Pinout & Package
TPS72727DSET is housed in a 1.5-mm × 1.5-mm WSON-6 (DSE) package with wettable flanks, rated for –40°C to +125°C operation. The exposed pad is not electrically connected and may be left floating or grounded for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output | Delivers 2.7 V to load; requires ≥1.0-μF X5R/X7R ceramic capacitor to GND for stability. |
| 2 (NC) | No connection | Internally unconnected; may be tied to GND to improve thermal dissipation. |
| 3 (GND) | Ground reference | Primary return path for load and ground pin current (110 μA at 200 mA); must be low-impedance. |
| 4 (EN) | Enable control | Active-high logic input; >0.9 V enables regulator, <0.4 V reduces IGND to 120 nA in shutdown. |
| 5 (NC) | No connection | Internally unconnected; may be tied to GND to improve thermal dissipation. |
| 6 (IN) | Input supply | Accepts 2.0–5.5 V; requires low-ESR input capacitor if source impedance is high or transients are fast. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow IQ | 7.9 μA quiescent current enables >10-year shelf life in coin-cell–powered IoT endpoints. |
| Fast Load Transient | ±50 mV deviation for 200 mA load steps-critical for maintaining RF IC bias stability during TX bursts. |
| Stable with 1.0-μF Ceramic | No external compensation needed; supports compact, low-BOM-count designs in space-constrained modules. |
| Factory-Programmed Output | 2.7 V set permanently in EEPROM-eliminates resistor tolerance errors and layout sensitivity. |
| High PSRR at Low Frequency | 70 dB at 1 kHz rejects ripple from buck converter switching frequencies and their harmonics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS72727YFF | Same 2.7-V output and specs, but in 4-ball DSBGA (1.2 mm × 0.8 mm) - 0.4-mm pitch, no exposed pad. | Better suited for ultra-thin wearables where board thickness < 0.6 mm is critical; less thermal mass than DSE. | Choose YFF for space-constrained PCBs; choose DSE for better thermal performance and manufacturability. |
| TPS7A0227PDBVR | 2.7-V, 200-mA LDO with 25 nA IQ (lower), but 200 mV dropout at 200 mA (higher) and 300 mV PSRR @ 1 kHz (lower). | Optimized for extreme ultra-low-power sleep modes, not RF noise rejection; requires larger VIN–VOUT margin. | Select TPS7A0227PDBVR only when sub-μA IQ dominates design priority over transient response and PSRR. |
Compared with TPS72727YFF, the TPS72727DSET offers superior thermal resistance (190.5°C/W vs 160°C/W) and easier rework; compared with TPS7A0227PDBVR, it delivers 45 dB higher PSRR at 1 kHz and 70 mV lower dropout at full load-making it preferred for RF-critical 2.7-V rails.

FAQ
What is the maximum input voltage rating for the TPS72727DSET?
The TPS72727DSET has an absolute maximum input voltage of +6.0 V. However, the recommended operating range is 2.0 V to 5.5 V. Exceeding 5.5 V risks violating safe operating area limits and may trigger internal protection circuits. Operation above 6.0 V can cause permanent damage per the Absolute Maximum Ratings table in the SBVS128F datasheet.
Does the TPS72727DSET require an input capacitor for stability?
The TPS72727DSET does not require an input capacitor for basic stability, but TI recommends a 0.1-μF to 1.0-μF low-ESR ceramic capacitor from IN to GND. This improves transient response, reduces noise coupling from upstream sources, and mitigates effects of high source impedance-especially critical in battery-powered systems with long PCB traces feeding the TPS72727DSET.
Can the TPS72727DSET be used with a 0.47-μF output capacitor?
No-the TPS72727DSET is specified and tested for stability only with output capacitance ≥1.0 μF. Using 0.47 μF violates the minimum requirement stated in Section 8.2.1.1 and may cause oscillation or excessive overshoot during load transients. Always use ≥1.0 μF X5R or X7R ceramic capacitors with ESR < 200 mΩ for reliable operation of the TPS72727DSET.
What is the shutdown current of the TPS72727DSET when EN is pulled low?
When the EN pin is driven below 0.4 V, the TPS72727DSET enters shutdown mode with a nominal ground pin current of 120 nA at TJ = +25°C and VIN = 2 V. Over temperature (–40°C to +85°C), shutdown current rises to a maximum of 550 nA. This ultra-low shutdown current preserves battery energy in intermittently active systems using the TPS72727DSET.
Is the TPS72727DSET compatible with ceramic capacitors having 10% tolerance?
Yes-the TPS72727DSET is fully compatible with ±10% tolerance X5R and X7R ceramic capacitors, as confirmed in Section 8.2.1.1. TI specifies "1.0-μF or larger" with "maximum ESR < 200 mΩ", and standard 10%-tolerance ceramics meet both requirements. Avoid Z5U or Y5V types due to excessive capacitance loss over temperature and bias, which could destabilize the TPS72727DSET.
