Texas Instruments TLV7111930DSER

Overview

TLV7111930DSER 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 thermal/over-current protection - designed for power-sensitive portable devices including smartphones and handheld audio.

For engineers reviewing the TLV7111930DSER datasheet, TLV7111930DSER pinout, TLV7111930DSER application, or TLV7111930DSER equivalent, key selection criteria include dual independent enable control (EN1/EN2), active pulldown on both outputs, 150mV dropout at 200mA/2.8V, PSRR of 70dB at 1kHz, and stable operation with ≥0.1µF ceramic output capacitance.

Technical Context

The TLV7111930DSER implements two independent PMOS-based LDO regulators sharing a common input and ground, each with dedicated voltage reference and feedback path to minimize crosstalk. Each channel features separate EN pins with internal pull-down resistors (TLV711-D series), enabling reliable disable during processor GPIO three-state conditions.

It delivers high PSRR (70dB @ 1kHz) and low output noise (48µVRMS, 100Hz–100kHz), supports input voltages from 2.0V to 5.5V, and maintains regulation down to 140mV dropout for VOUT ≥ 3.3V. Thermal shutdown activates at +165°C and resets at +145°C.

FAQ

What are the exact output voltages of the TLV7111930DSER?

The TLV7111930DSER provides two fixed, factory-programmed output voltages: 1.9V on OUT1 and 3.0V on OUT2. These values are trimmed to ±2% accuracy over the full –40°C to +125°C junction temperature range and do not require external feedback resistors. The "1930" in the part number explicitly denotes this 1.9V/3.0V combination.

Does TLV7111930DSER support independent enable control for each output?

Yes, TLV7111930DSER features two independent enable inputs: EN1 controls OUT1 and EN2 controls OUT2. Both are active-high with internal 150kΩ pull-down resistors (characteristic of the TLV711-D series), ensuring each regulator remains off unless actively driven above 0.9V. This enables flexible power sequencing and selective rail shutdown.

What is the minimum output capacitance required for stability with TLV7111930DSER?

TLV7111930DSER is stable with an effective output capacitance of 0.1µF or greater. It is typically used with 1µF X5R/X7R ceramic capacitors placed close to the OUT pins, but smaller 0.1µF units are sufficient - reducing solution size and cost. The effective capacitance must remain ≥0.1µF under operating bias and temperature.

How does the active pulldown feature benefit TLV7111930DSER in portable systems?

The active pulldown circuit on both OUT1 and OUT2 of TLV7111930DSER rapidly discharges connected loads when the respective EN pin is deasserted. This prevents floating voltage states, eliminates residual charge that could cause unintended wake-up or latch-up, and ensures clean, deterministic power-down - especially critical in multi-rail mobile SoC architectures.

Is TLV7111930DSER compatible with 1.8V logic-level enable signals?

Yes, TLV7111930DSER accepts 1.8V logic-high signals on EN1 and EN2. Its enable threshold is specified as VHI = 0.9V (min) and VLO = 0.4V (max), so a 1.8V GPIO output comfortably exceeds the 0.9V turn-on threshold while remaining within the absolute maximum EN voltage rating (VIN + 0.3V). This ensures direct interfacing with modern low-voltage microcontrollers.
