Product details
Overview
TLV7113333DDSET from Texas Instruments is a dual-channel, 200mA low-dropout linear regulator with independent enable pins (EN1/EN2), fixed 3.3V outputs on both channels, and integrated active pulldown circuitry for rapid output discharge. It features 2% output accuracy over –40°C to +125°C, 150mV dropout at 200mA (VOUT = 3.3V), and 70dB PSRR at 1kHz - designed for power-sensitive portable devices requiring clean, sequenced dual-rail supplies.
For engineers reviewing the TLV7113333DDSET datasheet, TLV7113333DDSET pinout, TLV7113333DDSET application, or TLV7113333DDSET equivalent, this page delivers verified functional specifications, validated dual-regulator timing behavior, confirmed SON-6 package layout constraints, and real-world substitution guidance for handheld power management designs.
Technical Context
The TLV7113333DDSET implements two independent PMOS-based LDO regulators sharing a common input (IN) and ground (GND), each with dedicated enable (EN1/EN2) and output (OUT1/OUT2) terminals. Its architecture includes per-channel bandgap references, dedicated VREF paths to minimize crosstalk, and internal current limiting (220–550mA) with thermal shutdown at +165°C.
This device belongs to the TLV711-D series, distinguished by pull-down resistors on both EN pins (6kΩ typical) to ensure reliable disable during indeterminate GPIO states - a critical feature for processor-controlled power sequencing in battery-powered systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3V per channel (VOUT1 = VOUT2 = 3.3V); enables single-supply biasing of dual-core SoCs or I/O + core rails. |
| Max Output Current | 200mA per channel; supports simultaneous powering of RF transceivers and baseband processors in compact handsets. |
| Dropout Voltage | 150mV at 200mA (VOUT = 3.3V); allows operation from 3.45V input - critical for Li-ion battery discharge down to 3.5V. |
| Quiescent Current | 35µA per regulator (70µA total enabled); extends battery life in always-on sensor nodes and standby modes. |
| PSRR | 70dB at 1kHz; suppresses switching noise from DC/DC converters feeding the IN rail in mixed-signal portable designs. |
| Accuracy | ±2% over –40°C to +125°C; ensures consistent voltage margins for 3.3V-tolerant peripherals across industrial temperature range. |
| Enable Threshold | VHI = 0.9V, VLO = 0.4V; compatible with 1.8V/3.3V GPIOs without level-shifting in modern microcontrollers. |
Pinout & Package
TLV7113333DDSET is housed in a 1.5mm × 1.5mm SON-6 package with wettable flank terminations, optimized for automated optical inspection (AOI) and space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN1 | Enable control for Regulator 1 | Active-high input with 6kΩ internal pulldown; asserts OUT1 when ≥0.9V, disables it when ≤0.4V - prevents floating-state misfires. |
| 2 - IN | Input supply connection | Common input for both regulators; requires ≥2.0V and ≤5.5V; must be decoupled with ≥0.1µF ceramic capacitor near pin. |
| 3 - EN2 | Enable control for Regulator 2 | Independent active-high enable with 6kΩ internal pulldown; enables precise sequencing of dual 3.3V domains (e.g., RF + AP). |
| 4 - GND | Power ground reference | Single ground return for both regulators; must connect directly to low-impedance ground plane to minimize PSRR degradation. |
| 5 - OUT2 | Regulated 3.3V output 2 | Delivers up to 200mA; requires ≥1µF ceramic capacitor (X5R/X7R) placed adjacent to pin for stability and transient response. |
| 6 - OUT1 | Regulated 3.3V output 1 | Electrically isolated output with dedicated VREF; enables low-crosstalk dual-rail operation for noise-sensitive analog circuits. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs | EN1 and EN2 allow asynchronous startup/shutdown sequencing - essential for managing power-up order in multi-rail SoC systems. |
| Active pulldown on outputs | Internally discharges OUT1/OUT2 rapidly upon disable, preventing floating voltages that could damage downstream logic or cause latch-up. |
| Dedicated VREF per output | Eliminates inter-channel crosstalk during load transients - maintains ±15mV regulation stability even when one channel experiences 200mA step load. |
| Stable with 0.1µF effective COUT | Supports ultra-small footprint capacitors (e.g., 0402 X5R) in size-constrained wearables without compromising loop stability. |
| Thermal & overcurrent protection | Auto-recovers from fault conditions; cycles between current limit and thermal shutdown (165°C trip) to prevent permanent damage during sustained overload. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL7407LDR | 7-channel 200mA sink driver (not LDO); no voltage regulation; open-drain outputs only. | Designed for LED/relay driving, not power supply generation; cannot replace TLV7113333DDSET in voltage regulation roles. | Select only for high-side switch replacement - not a functional alternative for regulated 3.3V dual-rail generation. |
| TPS7A2033PDQNR | Single-channel 300mA LDO; 17µA IQ; no dual output or EN2; 0.5mm pitch DQN package. | Requires two devices to match dual-rail capability; lacks independent sequencing and crosstalk isolation of TLV7113333DDSET. | Use when higher current per rail (>200mA) or lower quiescent current is prioritized over integration and sequencing control. |
Compared with TPS7A2033PDQNR, TLV7113333DDSET provides integrated dual-rail control with sequencing and crosstalk suppression in half the board area, while TPL7407LDR serves entirely different load-driving functions and cannot substitute for voltage regulation.

FAQ
What is the maximum input voltage rating for TLV7113333DDSET?
The absolute maximum input voltage for TLV7113333DDSET is +6.0V, but the recommended operating range is 2.0V to 5.5V. Exceeding 5.5V may trigger undervoltage lockout (UVLO) or degrade long-term reliability - always maintain VIN ≤ 5.5V in production designs using TLV7113333DDSET.
Does TLV7113333DDSET require external capacitors, and what values are recommended?
Yes, TLV7113333DDSET requires external input and output capacitors. A minimum 0.1µF ceramic capacitor is needed at IN, and ≥1µF X5R/X7R ceramic capacitors are recommended at OUT1 and OUT2. These must be placed adjacent to their respective pins to ensure stability and optimal PSRR performance in TLV7113333DDSET applications.
How does the EN pin pulldown resistor affect system-level power sequencing with TLV7113333DDSET?
The TLV7113333DDSET integrates 6kΩ pulldown resistors on both EN1 and EN2 pins, ensuring automatic disable when GPIOs are tristated or unpowered during MCU boot. This prevents unintended regulator activation and eliminates need for external pull-down resistors - simplifying layout and improving reliability in TLV7113333DDSET-based power trees.
Can TLV7113333DDSET support different output voltages on OUT1 and OUT2?
No - TLV7113333DDSET is factory-programmed with identical 3.3V fixed outputs on both channels. For mismatched voltages (e.g., 1.8V + 3.3V), select TLV7111833DDSET or other variant part numbers. TLV7113333DDSET's dual 3.3V configuration is optimized for symmetric dual-rail loads like RF transceivers with separate PA and LNA supplies.
What thermal protection behavior does TLV7113333DDSET exhibit under sustained overload?
Under sustained overload, TLV7113333DDSET enters thermal shutdown at +165°C junction temperature, disabling both outputs. After cooling to +145°C, it automatically recovers and resumes regulation. This auto-restart cycle protects the device and PCB traces without requiring external intervention - a key safety feature in TLV7113333DDSET deployments.
