Product details
Overview
TPS72715YFFT from Texas Instruments is a 1.5-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. It powers RF-sensitive blocks in battery-constrained portable devices such as Bluetooth transceivers and smartphone application processors.
For engineers reviewing the TPS72715YFFT datasheet, TPS72715YFFT pinout, TPS72715YFFT application, or TPS72715YFFT equivalent, key selection criteria include its 2% output accuracy over –40°C to +125°C, stability with 1.0-µF ceramic output capacitance, 70 dB PSRR at 1 kHz, and active-high enable with 0.9 V logic threshold-critical for low-power sequencing and noise-sensitive analog/RF subsystems.
Technical Context
The TPS72715YFFT employs a PMOS pass transistor enabling ultra-low dropout and eliminating reverse-current conduction risk without external diodes. Its factory-programmed EEPROM sets the 1.5-V output voltage, eliminating external feedback resistors and ensuring tight initial accuracy.
Internal soft-start limits inrush current to ≤400 mA during turn-on, while thermal shutdown (trip at +160°C, reset at +140°C) and current limiting (300–550 mA) provide fault protection. The device achieves 70 dB PSRR at 1 kHz and maintains <±65 mV load transient deviation under 250 mA steps with 1-µF COUT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2% over load, line, and temperature (–40°C to +125°C); factory EEPROM-programmed, no external resistors required. |
| Max Output Current | 250 mA continuous; internal current limit clamps at 300–550 mA to prevent damage during overload. |
| Quiescent Current | 7.9 µA typical at 10 mA load; enables >1-year battery life in always-on sensor nodes or remote controls. |
| Dropout Voltage | 65 mV typical at 100 mA; allows operation from 1.565 V input, critical for single-cell Li-ion or coin-cell systems. |
| PSRR @ 1 kHz | 70 dB minimum; suppresses switching noise from adjacent DC/DC converters feeding RF front-ends or ADCs. |
| Load Transient Response | ±50 mV max deviation for 200 mA load step (1 µs edge); sustains stable 1.5-V supply for burst-mode wireless transceivers. |
| Enable Threshold | VEN(HI) = 0.9 V min; compatible with 1.2-V and 1.8-V GPIOs; VEN(LO) = 0.4 V max ensures clean shutdown. |
| Capacitor Requirement | Stable with 1.0-µF X5R/X7R ceramic COUT; eliminates need for tantalum or large bulk capacitors in space-constrained layouts. |
Pinout & Package
TPS72715YFFT uses a 4-ball, 0.4-mm pitch wafer-level chip-scale package (DSBGA-4), measuring 1.20 mm × 0.80 mm. Ball A1 is marked by a top-side dot for 1.5-V, 1.8-V, 2.8-V, and 4.8-V variants; GND is marked for other voltages.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | EN (Enable) | Active-high digital control input; drives regulator ON above 0.9 V, OFF below 0.4 V; draws ≤500 nA leakage. |
| A2 | IN (Input) | Main power input (2.0–5.5 V); requires 0.1–1.0 µF ceramic bypass capacitor for optimal transient rejection. |
| B1 | GND (Ground) | Power return path; ground pin current is 7.9 µA (no load) to 130 µA (250 mA load), directly impacting system efficiency. |
| B2 | OUT (Output) | Regulated 1.5-V output; must connect ≥1.0 µF ceramic capacitor to GND for stability and low-noise performance. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow IQ | 7.9 µA quiescent current enables multi-year operation on coin cells in IoT sensors and wearables. |
| Factory-Programmed Output | 1.5-V output set via EEPROM-no external resistors needed, eliminating BOM cost and layout area for feedback network. |
| RF-Low-Noise Operation | 33.5 µVRMS integrated output noise (100 Hz–100 kHz); avoids spectral contamination of sensitive RF receivers. |
| Fast Load Transient Response | ±50 mV deviation for 200 mA load step; maintains voltage integrity during burst-mode transmission in Bluetooth/Zigbee modules. |
| Thermal & Current Protection | Auto-cycling thermal shutdown (+160°C trip) and current limit (300–550 mA) prevent permanent damage during short circuits or overloads. |
| Small-Footprint Packaging | 1.20 mm × 0.80 mm DSBGA-4 footprint saves >60% board area vs. comparable SON packages-ideal for ultra-thin handsets. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS72715DSE | Same electrical specs but in 1.5-mm × 1.5-mm WSON-6 package; includes NC pins and larger thermal pad. | Better thermal performance (RθJA = 190.5°C/W vs. 160°C/W) suits higher ambient or sustained 250-mA loads. | Select TPS72715DSE when PCB layout allows larger footprint and thermal management is prioritized over miniaturization. |
| MCP1700T-1502E/TT | 1.5-V fixed LDO with 1.8 µA IQ, 600-mA rating, but 300 mV dropout at 250 mA and requires 2.2-µF COUT for stability. | Lacks RF-grade PSRR (55 dB @ 1 kHz) and fast transient response; suitable only for non-RF digital logic rails. | Choose MCP1700T-1502E/TT only for cost-sensitive, non-noise-critical applications where 300-mV dropout is acceptable. |
Compared with TPS72715DSE, the TPS72715YFFT trades thermal margin for 64% smaller footprint-essential for sub-5-mm-thick devices. Versus MCP1700T-1502E/TT, it delivers superior RF immunity and transient fidelity at the cost of higher unit price and lower current capability.

FAQ
What is the maximum input voltage rating for the TPS72715YFFT?
The TPS72715YFFT has an absolute maximum input voltage (VIN) rating of +6.0 V. Operating beyond this value risks permanent damage. For reliable long-term operation, TI specifies the recommended VIN range as 2.0 V to 5.5 V-ensuring proper regulation, low dropout, and thermal safety across all load and temperature conditions defined in the datasheet.
Does the TPS72715YFFT require an input capacitor for stability?
The TPS72715YFFT does not require an input capacitor for basic stability, but TI strongly recommends a 0.1-µF to 1.0-µF ceramic capacitor between IN and GND. This capacitor improves transient response, reduces input ripple coupling, and mitigates noise from upstream sources-especially critical when the device is powered from a shared DC/DC converter rail in RF-sensitive designs.
How does the enable pin (EN) function on the TPS72715YFFT?
The EN pin on the TPS72715YFFT is active-high: driving it to ≥0.9 V enables regulation, while pulling it ≤0.4 V places the device in shutdown mode with only 120 nA ground current. The pin draws ≤500 nA, making it compatible with low-drive GPIOs. If shutdown is unused, EN may be tied directly to IN without external components.
Can the TPS72715YFFT be used with a 0.47-µF output capacitor?
No-the TPS72715YFFT is specified and tested for stability only with ≥1.0-µF ceramic output capacitance (X5R/X7R). Using 0.47 µF violates the minimum requirement and risks oscillation, especially under load transients or across temperature extremes. TI's design guidelines explicitly state 1.0 µF as the lower bound for guaranteed stability and transient performance.
What is the thermal shutdown behavior of the TPS72715YFFT?
The TPS72715YFFT activates thermal shutdown at approximately +160°C junction temperature and resets at +140°C. During sustained overload, it cycles between shutdown and regulation-limiting average power dissipation but degrading reliability if repeatedly triggered. For robust operation, design must keep TJ ≤+125°C using layout techniques like thermal vias and copper pours, as specified in the TPS72715YFFT thermal metrics table.
