Product details
Overview
TLV7111830DSET from Texas Instruments is a dual-channel, 200mA low-dropout linear regulator with fixed 1.8V and 3.0V outputs, 2% output accuracy over –40°C to +125°C, 150mV dropout at 200mA (VOUT = 2.8V), and 70dB PSRR at 1kHz - designed for power-sensitive portable electronics including smartphone baseband and RF subsystems.
For engineers reviewing the TLV7111830DSET datasheet, TLV7111830DSET pinout, TLV7111830DSET application, or TLV7111830DSET equivalent, key selection criteria include independent enable control per channel, active pulldown on both EN pins (D-series), thermal/overcurrent protection, and stability with ≥0.1µF ceramic output capacitance.
Technical Context
The TLV7111830DSET integrates two independent PMOS-based LDO regulators sharing a common IN and GND, each with dedicated VREF and EN pin. Its D-series variant includes internal pull-down resistors on EN1 and EN2 (6mA max IEN) to ensure reliable shutdown during indeterminate GPIO states.
Each regulator features dedicated bandgap reference, current-limit protection (220–550mA), thermal shutdown (165°C trip), and undervoltage lockout (1.9V VIN). Output crosstalk is minimized via separate VREF paths and optimized internal routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltages | 1.8V (OUT1) and 3.0V (OUT2), factory OTP-programmed, ±2% tolerance over full temperature range |
| Max output current | 200mA per channel - supports simultaneous dual-rail loads in compact handheld devices |
| Dropout voltage | 150mV at 200mA and VOUT = 2.8V - enables operation from single-cell Li-ion (3.0V min VIN) |
| Quiescent current | 35µA per regulator (70µA total when both enabled) - extends battery life in always-on subsystems |
| PSRR | 70dB at 1kHz - suppresses switching noise from adjacent DC/DC converters in RF-sensitive applications |
| Stability | Stable with ≥0.1µF ceramic output capacitance - allows use of small 0201/0402 MLCCs in space-constrained layouts |
| Enable logic | Active-high EN1/EN2 with 0.9V VIH and 0.4V VIL; internal 6mA pull-down ensures default-off behavior |
Pinout & Package
TLV7111830DSET is housed in a 1.5mm × 1.5mm SON-6 package with wettable flanks, optimized for automated optical inspection (AOI) and thermal performance (θJT = 6°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN1 | Enable input for regulator 1 (1.8V) | Drives OUT1 on >0.9V; internal 6mA pull-down forces shutdown if left floating or weakly driven |
| 2 - IN | Input supply rail | Shared input for both regulators; requires local 1µF ceramic decoupling to GND |
| 3 - EN2 | Enable input for regulator 2 (3.0V) | Drives OUT2 on >0.9V; independent control enables staggered power-up sequences |
| 4 - GND | Power ground reference | Single ground connection point - critical for minimizing crosstalk between output rails |
| 5 - OUT2 | Regulated 3.0V output | Delivers up to 200mA; requires 1µF ceramic capacitor to GND for transient stability |
| 6 - OUT1 | Regulated 1.8V output | Delivers up to 200mA; dedicated VREF minimizes interference from OUT2 load transients |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs | EN1 and EN2 allow precise sequencing of 1.8V and 3.0V rails - essential for FPGA I/O and core voltage ramp requirements |
| Active pulldown on EN pins | 6mA internal pull-down prevents false turn-on during processor boot or reset - eliminates need for external pull-down resistors |
| Dedicated VREF per output | Minimizes crosstalk between channels; measured <1mV perturbation on one output when other channel experiences 100mA load step |
| Thermal and current limit protection | Auto-recovery thermal shutdown (165°C trip / 145°C reset) and foldback current limiting prevent damage during short-circuit faults |
| Low-noise operation | 48µVRMS output noise (100Hz–100kHz) - suitable for powering RF transceivers and precision analog circuitry |

FAQ
What are the exact output voltages and accuracy of TLV7111830DSET?
TLV7111830DSET provides fixed 1.8V on OUT1 and 3.0V on OUT2, with ±2% DC accuracy over the full operating junction temperature range of –40°C to +125°C. This specification is guaranteed under all load, line, and temperature conditions per the Electrical Characteristics table in the SBVS142A datasheet.
Does TLV7111830DSET require external pull-down resistors on EN1 and EN2?
No. TLV7111830DSET is a D-series device featuring internal 6mA pull-down resistors on both EN1 and EN2 pins. This design ensures reliable shutdown when enable signals are floating or driven by weak GPIOs - eliminating the need for external components and simplifying layout.
What is the minimum output capacitance required for stability with TLV7111830DSET?
TLV7111830DSET is stable with an effective output capacitance of 0.1µF or greater. While 1µF X5R/X7R ceramic capacitors are recommended for optimal transient response, the device maintains phase margin with smaller values - enabling use of 0.22µF or 0.47µF MLCCs in size-constrained designs.
How does TLV7111830DSET handle overcurrent or thermal faults?
TLV7111830DSET incorporates foldback current limiting and thermal shutdown. During overload, it limits output current to 220–550mA depending on VIN, then cycles between current limit and thermal shutdown (trip at +165°C, reset at +145°C) until the fault clears - protecting both the IC and downstream circuitry without latch-up.
Can TLV7111830DSET be used in applications requiring different output voltage combinations?
No - TLV7111830DSET is factory-programmed for 1.8V/3.0V only. The TLV711 family supports other combinations (e.g., 1.5V/2.5V, 3.3V/3.3V) via distinct part numbers (e.g., TLV7111525DSET, TLV7113333DSET), each with OTP-set outputs. Voltage selection must be made at order time.
