Product details
Overview
TLV7101828DSER from Texas Instruments is a dual-channel, 200mA low-dropout linear regulator with fixed 1.8V and 2.8V outputs in a 1.5mm × 1.5mm SON-6 package. It delivers 2% output accuracy over –40°C to +125°C, 150mV dropout at 200mA/2.8V, and 70dB PSRR at 1kHz - enabling compact, low-noise power for RF-sensitive portable applications such as smartphone baseband and application processors.
For engineers reviewing the TLV7101828DSER datasheet, TLV7101828DSER pinout, TLV7101828DSER application, or TLV7101828DSER equivalent, key selection criteria include independent enable control per channel (EN1/EN2), dedicated VREF per output minimizing crosstalk, stable operation with ≥0.1µF ceramic output capacitance, and thermal/overcurrent protection for robust system-level power management.
Technical Context
The TLV7101828DSER integrates two independent PMOS-based LDO regulators sharing a common input (IN) and ground (GND), each with dedicated enable (EN1/EN2) and output (OUT1/OUT2) pins. Its architecture features separate internal voltage references per channel to suppress inter-channel crosstalk during load transients.
Each regulator operates with ultra-low quiescent current (35µA per channel active, 70µA both enabled), supports input voltages from 2.0V to 5.5V, and maintains regulation down to 150mV dropout at full 200mA load on the 2.8V rail - critical for battery-powered systems operating near end-of-life voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | Fixed 1.8V (OUT1) and 2.8V (OUT2); eliminates external feedback resistors and simplifies layout for dual-rail SoC supplies. |
| Max Output Current | 200mA per channel; sufficient to power core logic and I/O rails of mid-tier application processors and RF transceivers. |
| Dropout Voltage | 150mV at 200mA/2.8V; enables >95% efficiency at 3.0V input, extending battery runtime in portable devices. |
| PSRR @ 1kHz | 70dB; suppresses switching noise from upstream DC/DC converters, preserving signal integrity in RF and audio subsystems. |
| Accuracy | ±2% over –40°C to +125°C; ensures reliable operation across industrial and automotive temperature ranges without calibration. |
| Quiescent Current | 35µA per enabled regulator; reduces standby power loss in always-on sensor or communication modules. |
| Enable Threshold | VHI = 0.9V, VLO = 0.4V; compatible with 1.8V GPIOs and provides clean, noise-immune channel control. |
Pinout & Package
Package: 1.5mm × 1.5mm SON-6 (DSE), thermally enhanced, lead-free, RoHS-compliant surface-mount package with exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN1 | Enable input for OUT1 | Active-high control; drives OUT1 into shutdown when ≤0.4V, eliminating leakage current in unused rails. |
| 2 - IN | Input supply | Common input for both regulators; requires local 1µF ceramic decoupling to GND for stability. |
| 3 - EN2 | Enable input for OUT2 | Independent active-high control; allows staggered power-up or dynamic rail disabling without affecting OUT1. |
| 4 - GND | Ground reference | Single ground connection point; board layout must tie VIN and VOUT ground planes only here to minimize PSRR degradation. |
| 5 - OUT2 | 2.8V regulated output | Delivers up to 200mA; requires 1µF ceramic capacitor directly to GND for optimal transient response and noise performance. |
| 6 - OUT1 | 1.8V regulated output | Delivers up to 200mA; dedicated VREF minimizes crosstalk from OUT2 load steps, critical for noise-sensitive analog circuits. |
Key Features
| Feature | Design Value |
|---|---|
| Dedicated VREF per output | Reduces inter-channel crosstalk by >20dB during simultaneous load transients, preserving ADC reference stability and RF receiver SNR. |
| Stable with 0.1µF COUT | Enables use of small-footprint, high-bias-derating capacitors (e.g., 0402 X5R) in space-constrained mobile PCBs without compromising loop stability. |
| Thermal & overcurrent protection | Auto-recovers from fault conditions; prevents permanent damage during short-circuit or overheating events in unattended embedded systems. |
| Low 35µA quiescent current per channel | Extends battery life in always-on wearable sensors and IoT edge nodes where microamp-level sleep current is mandatory. |
| 70dB PSRR at 1kHz | Attenuates ripple from noisy buck converters feeding the IN pin, eliminating need for additional LC filtering in compact designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLS850F0TESK | Single-channel 5V-input automotive LDO (500mA), no dual-output capability; includes watchdog and reset functions. | Designed for ASIL-B safety-critical ECU power; lacks independent dual-rail control and low-PSRR optimization for RF. | Select TLS850F0TESK only when functional safety monitoring is required and dual-rail independence is unnecessary. |
| TPS7A202818PDBVR | Dual 200mA LDO with 2.8V/1.8V outputs, but uses SOT-23-8 package (2.9mm × 1.6mm); higher 250mV dropout at 200mA. | Larger footprint and lower efficiency limit use in ultra-thin mobile designs; identical electrical specs otherwise. | Choose TPS7A202818PDBVR if board space permits larger package and thermal performance is less constrained than in handheld form factors. |
Compared with TLS850F0TESK and TPS7A202818PDBVR, TLV7101828DSER uniquely combines dual-rail independence, 1.5mm × 1.5mm footprint, and 150mV dropout - making it optimal for space- and efficiency-critical portable electronics where channel isolation and battery longevity are primary design goals.

FAQ
What are the exact output voltages and maximum load current per channel of the TLV7101828DSER?
The TLV7101828DSER provides fixed 1.8V on OUT1 and 2.8V on OUT2, each capable of delivering up to 200mA continuous output current. These values are factory-programmed and non-adjustable; the "1828" in the part number explicitly denotes the 1.8V/2.8V output combination. Electrical specifications confirm ±2% accuracy across –40°C to +125°C and stable regulation under full 200mA load per rail.
Does the TLV7101828DSER require external capacitors, and what are the minimum recommended values?
Yes, the TLV7101828DSER requires external input and output capacitors. A minimum 1µF X5R/X7R ceramic capacitor is recommended from IN to GND, and 1µF from each OUTx to GND for optimal transient response and PSRR. However, the device is stable with as little as 0.1µF effective output capacitance - enabling use of smaller, high-bias-derating capacitors in space-constrained layouts. The TLV7101828DSER datasheet specifies ESR < 200mΩ for best performance.
How does the TLV7101828DSER handle thermal overload or output short-circuit conditions?
The TLV7101828DSER incorporates internal thermal shutdown (trip at +165°C, reset at +145°C) and overcurrent protection (220–550mA current limit). During overload, it enters constant-current mode until thermal shutdown activates; upon cooling, it auto-restarts. This protects against permanent damage in fault scenarios like PCB shorts or excessive ambient temperature - a key reliability feature confirmed in the Absolute Maximum Ratings and Functional Block Diagram of the TLV7101828DSER datasheet.
Can the TLV7101828DSER be used with a 3.3V input supply to power both 1.8V and 2.8V rails simultaneously?
Yes, the TLV7101828DSER supports input voltages from 2.0V to 5.5V, making 3.3V an ideal source. At 3.3V input, the 2.8V rail has 500mV headroom (well above its 150mV dropout requirement), and the 1.8V rail has 1.5V headroom - ensuring both channels remain fully regulated under full 200mA load. Line regulation data (Figures 1–4) confirms <5mV variation on both outputs across 3.3V ±10% input variation.
What is the quiescent current behavior of the TLV7101828DSER when only one channel is enabled?
When only one channel is enabled (e.g., EN1 high, EN2 low), the TLV7101828DSER draws 35µA quiescent current - matching the spec for a single enabled regulator. With both EN1 and EN2 high, IQ rises to 70µA typical. This per-channel IQ scaling is explicitly documented in the Electrical Characteristics table and enables precise power budgeting in systems where one rail remains active while the other is disabled for sleep-mode operation.
