Product details
Overview
TLV7112525DSER from Texas Instruments is a dual-channel, 200mA low-dropout linear regulator with fixed 2.5V outputs per channel, 2% output accuracy over temperature, 35µA quiescent current per regulator, and 70dB PSRR at 1kHz - designed for power-sensitive portable devices including smartphones and handheld audio players.
For engineers reviewing the TLV7112525DSER datasheet, TLV7112525DSER pinout, TLV7112525DSER application, or TLV7112525DSER equivalent, key selection considerations include dual independent enable control (EN1/EN2), active pulldown on both outputs, dedicated VREF per channel to minimize crosstalk, and stable operation with ≥0.1µF ceramic output capacitance.
Technical Context
The TLV7112525DSER integrates two independent PMOS-based LDO regulators sharing a common input but featuring separate EN pins, ground-referenced feedback, and dedicated internal voltage references - enabling precise, isolated regulation of two 2.5V rails without mutual interference.
It includes integrated over-current and thermal protection, undervoltage lockout (1.9V), and an active pulldown circuit on both OUT1 and OUT2 to rapidly discharge loads during shutdown - critical for sequencing-sensitive applications in battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.5V per channel, fixed and factory-trimmed - eliminates external resistor networks and ensures consistent rail generation. |
| Max Output Current | 200mA per channel - supports moderate-power analog/digital subsystems such as RF front-ends or sensor interfaces. |
| Quiescent Current | 35µA per regulator (70µA total when both enabled) - extends battery life in always-on or low-duty-cycle portable devices. |
| Dropout Voltage | 150mV at 200mA and VOUT = 2.8V (typical); for 2.5V output, dropout remains ≤175mV - enables operation from single-cell Li-ion (3.0V min) with margin. |
| PSRR | 70dB at 1kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Accuracy | ±2% over –40°C to +125°C - guarantees reliable logic-level compliance and analog reference stability across industrial temperature range. |
| Enable Threshold | VEN(HI) = 0.9V, VEN(LO) = 0.4V - compatible with 1.8V/3.3V GPIOs and supports clean, glitch-free power sequencing. |
Pinout & Package
Package: 1.5mm × 1.5mm SON-6 (DSE), thermally enhanced, exposed pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN1 | Enable input for regulator 1 | Active-high control; >0.9V enables OUT1, <0.4V disables it with active pulldown - enables independent power gating of first rail. |
| 2 - IN | Input supply pin | Common input for both regulators; requires local 1µF ceramic decoupling to GND - minimizes input impedance and improves transient response. |
| 3 - EN2 | Enable input for regulator 2 | Active-high control; >0.9V enables OUT2, <0.4V disables it with active pulldown - allows staggered startup or independent sleep modes. |
| 4 - GND | Ground reference | Single ground connection for both regulators and internal circuitry - must be tied to low-impedance system ground plane near device. |
| 5 - OUT2 | Regulated 2.5V output 2 | Supplies second 2.5V rail; features active pulldown to discharge load when disabled - prevents floating or back-driving in multi-rail systems. |
| 6 - OUT1 | Regulated 2.5V output 1 | Supplies primary 2.5V rail; includes dedicated VREF and active pulldown - ensures isolation from OUT2 and fast turn-off. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs | EN1 and EN2 allow asynchronous control of each 2.5V rail - essential for power sequencing in SoC-based designs. |
| Active pulldown on both outputs | Forces OUT1/OUT2 to GND during disable - prevents unintended biasing of downstream circuitry and eliminates need for external bleed resistors. |
| Dedicated VREF per output | Eliminates crosstalk between channels - maintains ±2% accuracy on each rail even under mismatched load transients. |
| Stable with ≥0.1µF ceramic output cap | Supports miniature 0201/0402 MLCCs - reduces PCB area and BOM count while maintaining stability across temperature and bias. |
| Pull-down resistors on EN pins | Ensures default-disable state if EN lines float (e.g., during processor reset) - enhances system robustness without external components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLS850F0TESK | Automotive-grade dual LDO (5V/3.3V), higher IQ (50µA), AEC-Q100 qualified - no 2.5V/2.5V option | Targeted for automotive body electronics; lacks EN-pulldown and active pulldown on outputs | Select only for automotive environments requiring qualification; not drop-in for portable consumer designs. |
| TPS70251QPWPR | 2.5V/5.0V dual LDO, 250mA per channel, 85µA IQ, SOIC-8 package - different output combination and larger footprint | Used in industrial PLC I/O modules; no active pulldown, requires external EN pull-up | Choose when mixed-voltage rails are needed and board space permits SOIC-8; not suitable for ultra-low-IQ or compact layouts. |
Compared with TLS850F0TESK and TPS70251QPWPR, the TLV7112525DSER uniquely delivers matched 2.5V outputs, lowest quiescent current (35µA/reg), active pulldown, and 1.5mm × 1.5mm SON-6 packaging - making it optimal for space-constrained, battery-operated dual-rail systems requiring tight regulation and fast shutdown.

FAQ
What is the output voltage configuration of the TLV7112525DSER?
The TLV7112525DSER provides two independent, fixed 2.5V outputs - OUT1 and OUT2 - each trimmed at the factory to ±2% accuracy over –40°C to +125°C. The "2525" in the part number explicitly denotes this dual 2.5V configuration, and no external resistors are required to set the voltage.
Does the TLV7112525DSER support independent enable control for each output?
Yes, the TLV7112525DSER features two dedicated enable pins: EN1 controls OUT1 and EN2 controls OUT2. Each is active-high with thresholds of 0.9V (enable) and 0.4V (disable), and both include internal pull-down resistors - ensuring safe default-off behavior during system reset or GPIO initialization.
What is the minimum output capacitance required for stability with the TLV7112525DSER?
The TLV7112525DSER is stable with an effective output capacitance of 0.1µF or greater. While 1µF X5R/X7R ceramic capacitors are recommended for optimal PSRR and noise performance, smaller 0.1µF–0.22µF MLCCs (e.g., 0201 or 0402) are viable in space-constrained designs - provided their bias-derated capacitance remains ≥0.1µF.
How does the active pulldown feature function on the TLV7112525DSER outputs?
When either EN1 or EN2 is driven low, the corresponding output (OUT1 or OUT2) is actively pulled to GND via an internal NMOS switch - discharging external capacitive loads quickly and preventing floating voltages. This eliminates the need for external bleed resistors and ensures predictable power-down behavior in multi-rail systems.
Is the TLV7112525DSER compatible with single-cell Li-ion battery input?
Yes, the TLV7112525DSER operates from 2.0V to 5.5V input and maintains regulation down to a dropout of ~175mV at 200mA for 2.5V outputs. With a typical Li-ion cell voltage range of 3.0V–4.2V, the device delivers full 200mA per rail with ample headroom and meets all electrical specifications across the usable battery discharge curve.
