Product details
Overview
TLV711285285DDSER from Texas Instruments is a dual-channel, 200mA low-dropout linear regulator with fixed 2.85V and 2.85V outputs, 2% accuracy over temperature, 35µA quiescent current per channel, and 150mV dropout at 200mA - designed for power-sensitive portable applications including smartphones and handheld audio devices.
For engineers reviewing the TLV711285285DDSER datasheet, TLV711285285DDSER pinout, TLV711285285DDSER application, or TLV711285285DDSER equivalent, key selection criteria include dual independent enable control (EN1/EN2), active pulldown on both outputs, dedicated VREF per channel to minimize crosstalk, and stability with ≥0.1µF ceramic output capacitance.
Technical Context
The TLV711285285DDSER integrates two independent PMOS-based LDO regulators in a single 1.5mm × 1.5mm SON-6 package, each with dedicated reference and feedback paths to suppress inter-channel crosstalk. It features internal current limiting (220–550mA) and thermal shutdown (165°C trip, 145°C reset).
Its EN1/EN2 pins include integrated pull-down resistors (6mA IEN), ensuring reliable disable during indeterminate GPIO states. The device operates across 2.0V–5.5V input and delivers stable 2.85V outputs with 70dB PSRR at 1kHz and 48µVRMS output noise (100Hz–100kHz).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.85V / 2.85V - fixed, factory OTP-programmed dual outputs; enables identical rail generation for dual-core processors or parallel sensor interfaces. |
| Max Output Current | 200mA per channel - supports simultaneous powering of RF transceivers and baseband ICs without derating. |
| Dropout Voltage | 150mV at 200mA - allows operation from 3.0V input while maintaining 2.85V output, critical for Li-ion battery discharge profiles. |
| 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 adjacent DC/DC converters in compact PCB layouts. |
| Accuracy | ±2% over –40°C to +125°C - ensures reliable logic-level compliance for 2.85V I/O domains across industrial temperature range. |
| Enable Threshold | VHI = 0.9V, VLO = 0.4V - compatible with 1.8V GPIOs; pull-down resistors prevent floating enable states during processor boot. |
Pinout & Package
Package: 1.5mm × 1.5mm SON-6 (DSE), moisture sensitivity level 1, RoHS-compliant, exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN1 | Enable input for regulator 1 | Active-high control with 6mA internal pulldown; asserts shutdown when ≤0.4V, enabling precise sequencing of first output rail. |
| 2 - IN | Input supply for both regulators | Shared 2.0–5.5V input; requires ≥0.1µF ceramic capacitor to GND for stability and EMI filtering. |
| 3 - EN2 | Enable input for regulator 2 | Independent active-high control with 6mA internal pulldown; allows staggered startup or independent power gating. |
| 4 - GND | Power ground reference | Single ground connection for both regulators; must be tied directly to output capacitor ground to minimize noise coupling. |
| 5 - OUT2 | Regulated 2.85V output 2 | Features active pulldown circuit to rapidly discharge load capacitance during shutdown - prevents floating bus states. |
| 6 - OUT1 | Regulated 2.85V output 1 | Includes dedicated bandgap reference and feedback path; isolated from OUT2 to limit crosstalk to <1mV. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs (EN1/EN2) | Enables flexible power sequencing - e.g., enable core logic before peripherals - without external logic or timing components. |
| Active pulldown on both outputs | Discharges output capacitors within milliseconds during shutdown, preventing unintended wake-up or latch-up in downstream circuits. |
| Dedicated VREF per output | Reduces inter-channel crosstalk to <1mV under dynamic load steps, critical for mixed-signal systems with analog and digital rails. |
| Stable with ≥0.1µF ceramic output cap | Supports ultra-small 0201/0402 MLCCs, reducing board area and cost versus traditional 1µF requirements. |
| Integrated pull-down resistors on EN pins | Eliminates need for external pull-down resistors when interfacing with weak-drive microcontroller GPIOs during reset or sleep. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLS850F2BHTSA1 | Automotive-grade AEC-Q100 qualified; higher 300mA per channel; 5V max input; no EN pull-down resistors. | Designed for 12V automotive systems with watchdog and reset functions; not suitable for portable battery-powered designs. | Select only for automotive applications requiring qualification and higher current; requires external EN pull-downs and different input filtering. |

FAQ
What are the exact output voltages of the TLV711285285DDSER?
The TLV711285285DDSER provides two fixed, factory-programmed output voltages: 2.85V on OUT1 and 2.85V on OUT2. This dual-matched configuration is confirmed in TI's SBVS142A datasheet and ordering nomenclature ('285' indicates 2.85V per channel). Both outputs maintain ±2% accuracy across –40°C to +125°C junction temperature.
Does the TLV711285285DDSER include internal pull-down resistors on its enable pins?
Yes, the TLV711285285DDSER includes internal pull-down resistors on both EN1 and EN2 pins (6mA typical), as specified in the "TLV711-D" variant description. This design ensures reliable disable when enable signals are floating or driven by weak GPIOs - a key differentiator from the TLV710 series and critical for robust power sequencing in portable systems.
What is the minimum output capacitance required for stability with the TLV711285285DDSER?
The TLV711285285DDSER is stable with an effective output capacitance of ≥0.1µF, as verified in the Electrical Characteristics table and Application Information section. While 1µF ceramic capacitors are shown in typical application circuits, smaller X5R/X7R MLCCs meeting the 0.1µF effective capacitance (under bias and temperature) are fully supported - enabling use of 0201- or 0402-size components.
How does the active pulldown feature function on the TLV711285285DDSER outputs?
The TLV711285285DDSER implements active pulldown circuitry on both OUT1 and OUT2. When either regulator is disabled (ENx ≤ 0.4V), its respective output is actively discharged to GND through an internal NMOS switch. This ensures rapid, controlled discharge of load capacitance - preventing floating nodes, unintended logic states, or latch-up in downstream circuits during power-down sequences.
What package type and dimensions does the TLV711285285DDSER use?
The TLV711285285DDSER uses the DSE package: a 1.5mm × 1.5mm SON-6 (Small Outline No-Lead) with 0.5mm pitch and an exposed thermal pad. Pinout is standardized per TI's SBVS142A datasheet: EN1 (1), IN (2), EN2 (3), GND (4), OUT2 (5), OUT1 (6). This ultra-compact footprint supports high-density portable PCB layouts.
