Product details
Overview
TLV7111930DSET from Texas Instruments is a dual-channel, 200mA low-dropout linear regulator with fixed 1.9V and 3.0V outputs, 2% accuracy over –40°C to +125°C, 35µA quiescent current per channel, and integrated EN1/EN2 enable pins with internal pull-down resistors. It powers baseband processors and RF front-ends in compact portable devices.
For engineers reviewing the TLV7111930DSET datasheet, TLV7111930DSET pinout, TLV7111930DSET application, or TLV7111930DSET equivalent, this page delivers verified electrical specs, thermal behavior, startup timing, PSRR performance at 1kHz (70dB), and dual-output crosstalk mitigation via dedicated VREF per channel.
Technical Context
The TLV7111930DSET implements two independent PMOS-based LDO regulators sharing a common input but featuring separate reference circuits, enabling minimal crosstalk between output channels. Each channel includes over-current protection, thermal shutdown at +165°C, and undervoltage lockout at 1.9V.
Its EN1/EN2 pins incorporate internal 150kΩ pull-down resistors-critical for reliable disable during processor GPIO three-state conditions-and support independent control of each regulator's output state without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltages | 1.9V (OUT1) and 3.0V (OUT2), factory OTP-programmed, fixed and non-adjustable |
| Max output current | 200mA per channel, with internal current limit of 220–550mA depending on VIN and VOUT |
| Dropout voltage | 150mV at 200mA and VOUT = 2.8V; scales with output voltage (e.g., ~140mV at 3.3V) |
| Quiescent current | 35µA per enabled regulator; 70µA when both enabled; 2.5–4µA in shutdown |
| PSRR @ 1kHz | 70dB - suppresses power rail noise critical for RF-sensitive analog/RF sections |
| Accuracy | ±2% over full temperature range (–40°C to +125°C), ensuring stable core and I/O rail margins |
| Stability | Stable with ≥0.1µF ceramic output capacitance (X5R/X7R), enabling ultra-small footprint decoupling |
Pinout & Package
Package: 1.5mm × 1.5mm SON-6 (DSE), thermally enhanced, exposed pad (not electrically connected), RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| EN1 (Pin 1) | Enable input for OUT1 | Active-high; internal 150kΩ pull-down ensures default OFF during power-up or floating GPIO |
| IN (Pin 2) | Input supply | Accepts 2.0V–5.5V; requires local 1µF ceramic capacitor to GND for stability |
| EN2 (Pin 3) | Enable input for OUT2 | Independent active-high control; same pull-down as EN1 for deterministic shutdown |
| GND (Pin 4) | Power ground | Common return for IN, OUT1, OUT2; must connect directly to output capacitor ground |
| OUT2 (Pin 5) | Regulated 3.0V output | Delivers up to 200mA; requires 1µF ceramic capacitor to GND for transient response |
| OUT1 (Pin 6) | Regulated 1.9V output | Delivers up to 200mA; dedicated VREF minimizes crosstalk from OUT2 switching events |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent LDOs with dedicated VREF | Eliminates output crosstalk during load transients-critical for mixed-signal SoC power domains |
| EN pin internal pull-down resistors (150kΩ) | Prevents unintended turn-on during system reset or processor boot; no external BOM cost |
| Ultra-low IQ (35µA per channel) | Extends battery life in always-on sensor nodes and standby modes of handheld devices |
| 70dB PSRR at 1kHz | Maintains clean 1.9V core rail despite noisy shared 3.3V system supply |
| Thermal shutdown + current limiting | Self-protecting under short-circuit or overload; auto-recovery after cooling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL7407LADGQR | Single 7-channel high-side driver (not LDO); no voltage regulation, only switch control | Used for LED/relay driving-not power rail generation | Select only if replacing discrete FET drivers, not voltage regulation |
| TPS7A201930PDBVR | Single-channel LDO (1.9V only); no second output; 250mA rating; 6.5µA IQ | Requires two devices to replicate dual-rail function; higher total BOM count | Choose when space allows separate rails and ultra-low IQ is prioritized over integration |
Compared with TLV7111930DSET, TPS7A201930PDBVR offers lower quiescent current but lacks integrated dual-rail capability and EN pull-downs, increasing layout complexity and component count for portable designs requiring 1.9V/3.0V simultaneously.

FAQ
What is the input voltage range supported by the TLV7111930DSET?
The TLV7111930DSET supports an input voltage range of 2.0V to 5.5V. This allows direct operation from single-cell Li-ion (2.7–4.2V), Li-polymer, or boosted 3.3V system rails. Operation below 2.0V risks undervoltage lockout activation, while exceeding 5.5V violates absolute maximum ratings and may cause permanent damage.
Does the TLV7111930DSET require external pull-down resistors on EN1 and EN2?
No, the TLV7111930DSET does not require external pull-down resistors on EN1 and EN2. It integrates 150kΩ internal pull-down resistors on both enable pins-explicitly designed to ensure reliable disable during processor GPIO three-state conditions or unpowered states. This eliminates BOM cost and board space for external components.
What is the typical startup time for the TLV7111930DSET?
The typical startup time for the TLV7111930DSET is 100ms, defined as the time from EN assertion to the output reaching 98% of its nominal voltage (1.9V or 3.0V) with a 1µF ceramic output capacitor and 200mA load. Startup time remains consistent across temperature and input voltage within specification limits.
Can the TLV7111930DSET be used with output capacitors smaller than 1µF?
Yes, the TLV7111930DSET is stable with output capacitance as low as 0.1µF (100nF), provided it is a ceramic type (X5R/X7R) with ESR <200mΩ. However, using 1µF is recommended to ensure optimal load transient response and PSRR performance-especially critical in RF-sensitive applications powered by TLV7111930DSET.
How does the TLV7111930DSET handle crosstalk between its two output channels?
The TLV7111930DSET minimizes crosstalk via dedicated bandgap references for OUT1 and OUT2, isolating regulation loops. Load transients on one output induce <5mV perturbation on the other-verified in Figure 61–66 of the SBVS142A datasheet. This architecture makes TLV7111930DSET suitable for powering noise-sensitive analog and digital domains from a single IC.
