Product details
Overview
TPS72719DSET from Texas Instruments is a 1.9-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 65-mV typical dropout at 100 mA, 7.9-μA quiescent current, and 70-dB PSRR at 1 kHz - optimized for battery-powered RF and portable consumer electronics.
For engineers reviewing the TPS72719DSET datasheet, TPS72719DSET pinout, TPS72719DSET application, or TPS72719DSET equivalent, key selection criteria include its ultralow IQ, fast load transient response (±50 mV for 200-mA step), stable operation with 1.0-μF ceramic output capacitor, and factory-programmed 1.9-V output without external resistors.
Technical Context
The TPS72719DSET employs a PMOS pass transistor enabling low dropout and eliminating reverse-body diode conduction issues common in NMOS-based LDOs. Its internal EEPROM sets the 1.9-V output voltage during manufacturing, removing need for external feedback networks.
It integrates active enable control (EN pin threshold: 0.9 V high, 0.4 V low), thermal shutdown (~160°C trip), overcurrent protection (typical 400-mA limit), and undervoltage lockout (1.90 V nominal). Ground pin current scales with load (110 μA at 200 mA) and temperature, supporting precise power budgeting in ultra-low-power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.9 V ±2% over –40°C to +125°C, factory-programmed via EEPROM - eliminates external resistor divider and associated tolerance/temperature drift. |
| Max Output Current | 250 mA continuous - supports moderate-power RF ICs and microcontrollers without external current boosting. |
| Quiescent Current | 7.9 μA typical - enables multi-year battery life in always-on sensor nodes and remote controls. |
| Dropout Voltage | 65 mV typical at 100 mA - allows operation from single-cell Li-ion (3.0 V min) or two-cell alkaline (2.4 V min) with margin. |
| PSRR @ 1 kHz | 70 dB - suppresses switching noise from upstream DC/DC converters feeding sensitive RF/analog circuitry. |
| Load Transient | ±50 mV for 200-mA step (1 μs edge) - maintains stable supply during burst-mode wireless transmission (e.g., Bluetooth LE). |
| Stability | Guaranteed with ≥1.0-μF X5R/X7R ceramic COUT - reduces BOM count and PCB area vs. tantalum or larger ceramics. |
Pinout & Package
TPS72719DSET uses the DSE (WSON-6) package: 1.50 mm × 1.50 mm, 0.5-mm pitch, exposed thermal pad (not electrically connected), moisture sensitivity level 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output | Delivers 1.9 V to load; requires 1.0-μF ceramic capacitor to GND for stability and transient response. |
| 2 (NC) | No connection | Internally unconnected; may be tied to GND to improve thermal dissipation but has no electrical function. |
| 3 (GND) | Ground reference | Return path for load, IN, and internal circuitry; must be low-impedance to minimize ground bounce during transients. |
| 4 (EN) | Enable control | Active-high logic input; >0.9 V enables regulator, <0.4 V disables it (120 nA shutdown current). |
| 5 (NC) | No connection | Internally unconnected; same thermal role as Pin 2 - optional GND tie for thermal enhancement. |
| 6 (IN) | Input supply | Accepts 2.0–5.5 V input; requires local 0.1–1.0-μF ceramic capacitor to GND for noise filtering and source impedance reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow IQ | 7.9 μA quiescent current enables >10-year battery life in coin-cell–powered IoT sensors. |
| Factory-programmed output | 1.9 V set permanently in EEPROM - eliminates external resistors, layout sensitivity, and calibration overhead. |
| Fast load transient response | ±50 mV deviation for 200-mA load step ensures reliable operation of RF transceivers during TX bursts. |
| High PSRR at low frequency | 70 dB at 1 kHz rejects ripple from buck converter switching frequencies and their harmonics. |
| Thermal & current protection | Integrated thermal shutdown (~160°C) and 400-mA current limit prevent damage during overload or poor heatsinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS72718DSET | Fixed 1.8-V output (vs. 1.9 V); identical package, IQ, PSRR, and transient specs. | Suitable where system logic or RF ICs require precisely 1.8 V instead of 1.9 V. | Select TPS72718DSET only if target load mandates 1.8 V; pinout and layout are identical. |
| MCP1700T-1902E/TT | 1.9-V fixed output, SOT-23-5 package, 1.6-μA IQ, 600-mA max current, 170-mV dropout at 250 mA. | Better current capability but higher dropout and lower PSRR (60 dB @ 1 kHz); not optimized for RF noise rejection. | Choose MCP1700T-1902E/TT for cost-sensitive, non-RF applications needing higher output current and smaller footprint. |
Compared with TPS72719DSET, TPS72718DSET offers identical performance at 1.8 V for compatibility with standard I/O voltages, while MCP1700T-1902E/TT trades RF-grade PSRR and ultralow IQ for higher current and lower cost in general-purpose portable designs.

FAQ
What is the output voltage tolerance of the TPS72719DSET over temperature and load?
The TPS72719DSET maintains ±2% output voltage accuracy across –40°C to +125°C junction temperature, 0–250 mA load current, and 2.0–5.5 V input voltage. This specification includes initial tolerance, line regulation (8 μV/V), and load regulation (20 μV/mA), ensuring stable 1.9-V rail for precision analog and RF circuits without external trimming.
Does the TPS72719DSET require an input capacitor for stability?
The TPS72719DSET does not require an input capacitor for basic stability, but Texas Instruments recommends a 0.1–1.0-μF ceramic capacitor from IN to GND. This improves transient response, reduces input ripple coupling, and mitigates source impedance effects - especially critical when powering from high-impedance sources like battery protection circuits or long PCB traces.
How does the enable pin (EN) function on the TPS72719DSET?
The EN pin on the TPS72719DSET is active-high with a 0.9-V turn-on threshold and 0.4-V turn-off threshold. When pulled above 0.9 V, the regulator powers up with 100-μs startup time; below 0.4 V, it enters shutdown mode drawing only 120 nA. The pin accepts standard CMOS/TTL logic levels and can be tied to IN if enable control is unnecessary.
Can the TPS72719DSET operate with a 1.0-μF ceramic output capacitor?
Yes - the TPS72719DSET is explicitly designed and tested to be stable with a minimum 1.0-μF X5R or X7R ceramic capacitor on the OUT pin. This eliminates need for larger or more expensive capacitors, reduces PCB area, and simplifies design compared to LDOs requiring 10–22-μF tantalum or aluminum electrolytic types.
What thermal protection features does the TPS72719DSET include?
The TPS72719DSET incorporates thermal shutdown that disables the output when junction temperature reaches ~160°C. After cooling to ~140°C, it automatically recovers. This cycling protects against permanent damage during sustained overload or inadequate heatsinking. For reliable operation, design must keep TJ ≤ +125°C under worst-case ambient and load conditions.
