Product details
Overview
TLV7111533DDSER from Texas Instruments is a dual-channel, 200mA low-dropout linear regulator with fixed 1.5V and 3.3V outputs, 2% accuracy over –40°C to +125°C, 150mV dropout at 200mA (VOUT = 2.8V), and 70dB PSRR at 1kHz - designed for power-sensitive portable applications including smartphone baseband and RF subsystems.
For engineers reviewing the TLV7111533DDSER datasheet, TLV7111533DDSER pinout, TLV7111533DDSER application, or TLV7111533DDSER equivalent, key selection criteria include independent enable control per channel, active pulldown on both EN pins, thermal/overcurrent protection, and stability with ≥0.1µF ceramic output capacitance.
Technical Context
The TLV7111533DDSER integrates two independent PMOS-based LDO regulators sharing a common input but featuring dedicated VREF and feedback paths to minimize crosstalk. Each channel includes internal current limiting and thermal shutdown, with EN1/EN2 pins incorporating pull-down resistors (6kΩ typical) to ensure reliable disable during indeterminate GPIO states.
It operates across 2.0V–5.5V input range and delivers regulated 1.5V/3.3V outputs with load regulation ≤15mV (0–200mA) and line regulation ≤5mV (VIN variation). Shutdown current is 2.5–4µA, and quiescent current is 35µA per enabled regulator.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltages | 1.5V (OUT1) and 3.3V (OUT2) - fixed, factory-programmed OTP outputs with no external resistor network required |
| Max output current | 200mA per channel - supports simultaneous dual-rail loads such as RF transceivers and baseband processors |
| Dropout voltage | 150mV at 200mA, VOUT = 2.8V - enables operation with minimal VIN–VOUT headroom in battery-powered systems |
| Accuracy | ±2% over –40°C to +125°C - ensures stable voltage delivery across automotive and industrial temperature ranges |
| PSRR | 70dB at 1kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input |
| Enable logic | Active-high EN1/EN2 with 6kΩ internal pulldown - prevents unintended startup when host MCU GPIOs float during boot |
| Stability | Stable with ≥0.1µF ceramic output capacitance - reduces BOM count and PCB area vs. traditional 1–10µF requirements |
Pinout & Package
Package: 1.5mm × 1.5mm SON-6 (DSE), thermally enhanced exposed pad, 0.5mm pitch, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN1 | Enable input for OUT1 | Drives OUT1 on when >0.9V; internal 6kΩ pulldown ensures default OFF state during reset or floating GPIO |
| 2 - IN | Input supply | Common input for both regulators; requires local 1µF ceramic decoupling to GND per datasheet guidance |
| 3 - EN2 | Enable input for OUT2 | Drives OUT2 on when >0.9V; independent control allows staggered power-up of 1.5V/3.3V domains |
| 4 - GND | Ground reference | Single ground pin shared by both regulators and internal circuitry; must connect directly to low-impedance ground plane |
| 5 - OUT2 | 3.3V regulated output | Delivers up to 200mA at 3.3V; requires 1µF ceramic capacitor to GND for optimal transient response |
| 6 - OUT1 | 1.5V regulated output | Delivers up to 200mA at 1.5V; dedicated VREF minimizes crosstalk from OUT2 load transients |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs | EN1 and EN2 allow precise sequencing of 1.5V and 3.3V rails - critical for SoC power-up compliance |
| Active pulldown on EN pins | 6kΩ internal resistors eliminate need for external pull-downs, reducing component count and layout complexity |
| Dedicated VREF per output | Minimizes inter-channel crosstalk (<1mV step-induced disturbance), essential for noise-sensitive RF analog blocks |
| Low IQ per regulator | 35µA quiescent current per enabled channel - extends battery life in always-on sensor or standby modes |
| Thermal + current protection | Auto-recovery thermal shutdown at +165°C and foldback current limit prevent 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 |
|---|---|---|---|
| TLS850F0TESK | Automotive-qualified AEC-Q100 Grade 1; 500mA per channel; integrated watchdog and reset generator | Targeted for automotive body electronics; not optimized for portable battery life | Select only if AEC-Q100 qualification and system monitoring features are required |
| TPS7A201533PDBVR | Lower IQ (6.5µA), no EN pulldown; 300mA per channel; same 1.5mm×1.5mm DSBGA package | Better suited for ultra-low-power always-on applications; requires external EN pull-downs | Choose when minimizing standby current is critical and board space allows external resistors |
Compared with TLS850F0TESK and TPS7A201533PDBVR, the TLV7111533DDSER uniquely balances low IQ (35µA/channel), built-in EN pulldowns, and industrial temperature rating in a minimal 2.25mm² footprint - making it optimal for cost- and size-constrained portable designs where automotive qualification is unnecessary.

FAQ
What are the fixed output voltages of the TLV7111533DDSER?
The TLV7111533DDSER provides two fixed output voltages: 1.5V on OUT1 and 3.3V on OUT2. These values are factory-programmed using OTP technology and cannot be adjusted externally. The part number encoding "1533" explicitly denotes these nominal outputs, and both channels maintain ±2% accuracy across –40°C to +125°C junction temperature.
Does the TLV7111533DDSER require external pull-down resistors on EN1 and EN2?
No, the TLV7111533DDSER does not require external pull-down resistors on EN1 or EN2. It integrates internal 6kΩ pull-down resistors on both enable pins, ensuring reliable disable during MCU reset or floating GPIO conditions. This eliminates two external components and simplifies layout - a key differentiator versus standard TLV710-series variants without pulldown.
What is the minimum output capacitance required for stability with the TLV7111533DDSER?
The TLV7111533DDSER is stable with an effective output capacitance of 0.1µF or greater. While 1µF X5R/X7R ceramic capacitors are recommended for optimal transient response and PSRR, the device's design accommodates smaller footprints - such as 0402 0.1µF capacitors - provided the effective capacitance (accounting for DC bias and temperature derating) remains ≥0.1µF.
How does the TLV7111533DDSER handle overcurrent or thermal faults?
Under overcurrent, the TLV7111533DDSER enters current-limit mode, sourcing a fixed current largely independent of output voltage until thermal shutdown triggers at +165°C. Once tripped, the device auto-recovers as it cools below +145°C. This cycle repeats if the fault persists. The PMOS pass element includes a body diode, so reverse voltage operation must be limited to ≤5% of rated output current to avoid damage.
Can the TLV7111533DDSER be used in automotive applications?
The TLV7111533DDSER is specified for operation from –40°C to +125°C junction temperature and meets industrial reliability standards, but it is not AEC-Q100 qualified. For automotive applications requiring formal qualification, TI recommends alternatives like the TLS850F0TESK. The TLV7111533DDSER is appropriate for non-safety-critical automotive infotainment or telematics accessories where full qualification is not mandated.
