Product details
Overview
TLV7111225DSET from Texas Instruments is a dual-channel, 200mA low-dropout linear regulator with fixed 1.2V and 2.5V outputs, 2% output accuracy over –40°C to +125°C, 150mV dropout at 200mA (VOUT = 2.8V), and 35µA quiescent current per channel. It serves as a compact, low-noise power supply for RF-sensitive portable electronics requiring independent, stable voltage rails.
For engineers reviewing the TLV7111225DSET datasheet, TLV7111225DSET pinout, TLV7111225DSET application, or TLV7111225DSET equivalent, this page delivers verified electrical specs, SON-6 package layout guidance, thermal protection behavior, EN pin pull-down functionality, and dual-rail crosstalk mitigation design insights.
Technical Context
The TLV7111225DSET integrates two independent PMOS-based LDO regulators sharing a common input and ground, each with dedicated VREF and active pulldown circuitry on its output. Its EN1/EN2 pins feature internal 150kΩ pull-down resistors-critical for reliable disable during processor GPIO three-state conditions.
It delivers high PSRR (70dB at 1kHz), supports ceramic output capacitors ≥0.1µF, and includes over-current and thermal shutdown protection. The device operates across 2.0V–5.5V input and maintains regulation down to 1.2V output, with load regulation ≤15mV across 0–200mA per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltages | 1.2V (OUT1) and 2.5V (OUT2) - fixed, factory-programmed, no external feedback required |
| Max output current | 200mA per channel - sufficient for baseband processors, RF transceivers, and sensor interfaces |
| Dropout voltage | 150mV at 200mA, VOUT = 2.8V - enables operation from single-cell Li-ion (3.0V min) with margin |
| Quiescent current | 35µA per regulator (70µA total enabled) - extends battery life in always-on subsystems |
| PSRR | 70dB at 1kHz - suppresses switching noise from upstream DC/DC converters |
| Accuracy | ±2% over –40°C to +125°C - ensures timing-critical logic and ADC reference stability |
| Enable threshold | VHI = 0.9V, VLO = 0.4V - compatible with 1.2V/1.8V I/O domains without level shifters |
Pinout & Package
TLV7111225DSET is housed in a 1.5mm × 1.5mm SON-6 (DSE) package with wettable flanks, optimized for space-constrained portable PCBs and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN1 (Pin 1) | Enable control for OUT1 | Active-high input with 150kΩ internal pull-down - prevents false turn-on during power-up or GPIO float |
| IN (Pin 2) | Input voltage supply | Shared input for both regulators; requires local 1µF ceramic decoupling to GND |
| EN2 (Pin 3) | Enable control for OUT2 | Independent active-high enable with same 150kΩ pull-down - enables staggered power sequencing |
| GND (Pin 4) | Power ground reference | Single ground connection point; board layout must tie VIN and VOUT ground planes here only |
| OUT2 (Pin 5) | Regulated 2.5V output | Delivers up to 200mA; requires 1µF ceramic capacitor to GND for stability and transient response |
| OUT1 (Pin 6) | Regulated 1.2V output | Delivers up to 200mA; dedicated VREF minimizes crosstalk from OUT2 load transients |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDOs with dedicated VREF | Eliminates output crosstalk during dynamic load changes on either rail - critical for mixed-signal SoCs |
| EN pin internal 150kΩ pull-down (TLV711-D series) | Ensures default-off state when host processor GPIO is unconfigured or tri-stated - improves system robustness |
| Stable with ≥0.1µF effective output capacitance | Supports small-footprint X5R/X7R ceramics - reduces BOM count and PCB area vs. larger tantalum alternatives |
| Active output pulldown circuit | Quickly discharges OUT1/OUT2 when disabled - prevents floating bias in downstream circuits (e.g., analog switches) |
| Thermal shutdown + current limit protection | Auto-recovery cycling under sustained overload - protects against shorted loads without external circuitry |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7101225DSET | No internal EN pull-down resistors; EN pins require external pull-down for default-off behavior | Suitable where host MCU GPIOs are actively driven during all states; less tolerant of floating EN lines | Select TLV7101225DSET only if board-level pull-downs are already implemented or GPIO control is fully managed |
| TPL7407LADGQR | 7-channel high-side driver with integrated 500mA LDO (not dual-output); different topology and pinout | Used for LED/display biasing and logic-level translation-not a direct dual-rail replacement | Consider only for non-LDO-specific functions; not a functional alternative for TLV7111225DSET's dual-regulator role |
Compared with TLV7111225DSET, TLV7101225DSET lacks EN pull-downs-increasing risk of unintended startup in unmanaged systems-while TPL7407LADGQR serves entirely different drive/bias functions and cannot replace dual-rail regulation.

FAQ
What output voltages does the TLV7111225DSET provide?
The TLV7111225DSET provides two fixed, factory-programmed output voltages: 1.2V on OUT1 (Pin 6) and 2.5V on OUT2 (Pin 5). These values are laser-trimmed during manufacturing and require no external resistive feedback network. Both outputs deliver up to 200mA with ±2% accuracy across –40°C to +125°C junction temperature.
Does TLV7111225DSET include internal pull-down resistors on its enable pins?
Yes, TLV7111225DSET includes internal 150kΩ pull-down resistors on both EN1 (Pin 1) and EN2 (Pin 3), as confirmed by the "TLV711-D" suffix in its ordering code. This ensures the regulators remain disabled during power-up, reset, or when host GPIOs are in high-impedance states-eliminating need for external pull-down components.
What is the minimum output capacitance required for TLV7111225DSET stability?
The TLV7111225DSET is stable with an effective output capacitance of 0.1µF or greater, as verified in the Electrical Characteristics table and Application Information section. For optimal PSRR and transient response, TI recommends using 1µF X5R/X7R ceramic capacitors placed adjacent to OUT1 and OUT2 pins, with ground connections tied directly to the GND (Pin 4) pad.
How does TLV7111225DSET handle output crosstalk between its two channels?
The TLV7111225DSET minimizes crosstalk via dedicated bandgap references for each output and independent pass transistor control. As shown in Figure 63–66 of the datasheet, load transients on one output induce <5mV perturbation on the other rail. This isolation is achieved without shared reference or feedback paths-making TLV7111225DSET suitable for mixed-signal SoCs with sensitive analog and digital domains.
What protection features are integrated into TLV7111225DSET?
TLV7111225DSET integrates over-current protection (220–550mA trip range), thermal shutdown (+165°C trip, +145°C reset), undervoltage lockout (1.9V VIN rising threshold), and ESD protection (2kV HBM, 500V CDM). During overload, it cycles between current limit and thermal shutdown until fault removal-no external protection circuitry is needed for typical portable use cases.
