TLV7101828QDSERQ1 개요
An LDO (Low-Dropout) linear regulator is a subclass of linear voltage regulator that maintains a stable output voltage when the input voltage is only marginally higher than the output voltage. Within the broader power-management hierarchy, LDOs sit beneath switching converters as the final clean-up stage: a DC-DC converter handles large step-down ratios at high efficiency, then a dual-channel LDO like the TLV7101828QDSERQ1 provides low-noise, accurate rails for sensitive analog and digital loads.
Key features of this part include independent enable pins per channel, very low quiescent current (typically under 40 µA combined at light load), and high PSRR (60 dB typical at 1 kHz per the device datasheet) which suppresses residual switching ripple from upstream converters. Each channel uses a PNP pass element architecture that achieves low dropout and stable operation with only 1 µF ceramic output capacitors.
Typical applications include powering automotive camera modules, infotainment processors, sensor fusion MCUs, and body controllers that need both a 1.8 V logic rail and a 2.8 V RF/sensor rail from a common 3.3 V or 5 V supply. The dual-channel integration halves the PCB footprint versus two discrete LDOs and simplifies power sequencing using two EN pins.
When designing with the TLV7101828QDSERQ1, follow the datasheet layout guidance: place input and output capacitors within 1–2 mm of the package, use X7R/X5R 1 µF ceramic parts, and keep the exposed thermal pad soldered to a continuous ground pour for adequate power dissipation. According to TI's automotive-grade qualification, the part is rated for operation across the full -40 °C to +125 °C ambient range required for underhood and cabin modules.

일반적인 애플리케이션
TLV7101828QDSERQ1 적합 용도: 6 애플리케이션s: Automotive Camera Module Power, Body Control Module (BCM) Rails, Infotainment Head Unit Power, Sensor Fusion / ADAS ECU, Industrial Handheld Scanner Power, Portable Medical Monitoring Device.
Automotive Camera Module Power
The TLV7101828QDSERQ1 is well matched to automotive camera modules that require a low-noise 1.8 V digital core rail and a 2.8 V analog/sensor rail. Each 200 mA channel comfortably supports an image sensor, ISP front-end, and serializer, while the AEC-Q100 Grade 1 qualification (-40 °C to +125 °C) ensures reliable operation across cabin and exterior camera environments. The independent EN pins let the MCU power-down the analog rail during standby to cut quiescent draw, while keeping the digital rail alive for wake-on-motion. Its 1 µF ceramic output stability simplifies BOM and shrinks PCB area versus discrete dual-LDO solutions, making it a compact, automotive-qualified power tree for surround-view and forward-camera applications.

Body Control Module (BCM) Rails
Body control modules in modern vehicles need multiple low-current rails for sensors, LIN/CAN transceivers, and microcontroller I/O. The TLV7101828QDSERQ1 supplies a clean 1.8 V for the MCU core and 2.8 V for analog sensor interfaces from a common 3.3 V or 5 V bus, with 200 mA per channel suiting BCM loads under 200 mA per rail. Independent EN pins enable selective rail shutdown for low-quiescent standby modes (e.g., key-off parasitic-current compliance). AEC-Q100 Grade 1 qualification supports the harsh automotive temperature range, and the WSON-6 1.5×1.5 mm package fits the small form factor of distributed BCM daughter boards.
추천
Infotainment Head Unit Power
Automotive infotainment head units require a low-noise 1.8 V rail for application processor I/O and a 2.8 V rail for codec/DDR reference circuits. The TLV7101828QDSERQ1's high PSRR rejects residual switching ripple from upstream DC-DC converters, ensuring clean audio and low-DDR jitter. The dual 200 mA channels share a single 1.5 × 1.5 mm WSON package, which is roughly half the board area of two discrete single-channel LDOs. AEC-Q100 Grade 1 qualification matches cabin electronics reliability targets, while independent EN control supports power-state transitions for fast processor wake-up.

Sensor Fusion / ADAS ECU
Sensor-fusion ECUs combine radar, IMU, and vision data, requiring clean rails for both a 1.8 V digital MCU and a 2.8 V analog front end. The TLV7101828QDSERQ1 delivers these rails with 200 mA per channel, adequate for radar baseband processors and IMU sensors. The exposed thermal pad of the WSON-6 package provides low thermal resistance to support continuous operation at 200 mA without derating. AEC-Q100 Grade 1 qualification is mandatory for ADAS safety-critical hardware, and the small 1.5 × 1.5 mm footprint preserves board area for additional sensor interface ICs.

Industrial Handheld Scanner Power
Beyond automotive, the TLV7101828QDSERQ1 fits battery-powered handheld scanners and HMI panels that need a 1.8 V logic rail and a 2.8 V display/imager rail from a single Li-ion cell. Each 200 mA channel can drive a small TFT display backlight driver, barcode imager, and BLE SoC simultaneously. The low quiescent current of the TLV710-Q1 family extends battery life in standby, while the WSON-6 footprint fits tightly inside compact handheld enclosures. The wide -40 °C to +125 °C operating range ensures operation in outdoor, cold-chain, and warehouse environments.

Portable Medical Monitoring Device
Battery-powered patient monitors and wearable health patches need a stable 1.8 V for the MCU/BLE SoC and a 2.8 V rail for analog front-end bio-sensor interfaces. The TLV7101828QDSERQ1 provides 200 mA per channel, sufficient for sensor excitation and signal-conditioning circuits, while its high PSRR keeps noise off low-amplitude ECG/EEG signals. The dual-rail integration halves board area, which is critical for compact wearable form factors. Independent EN pins support sleep modes between measurements, extending battery life for ambulatory devices.

설계 노트
Place the 1 µF X7R/X5R ceramic input and output capacitors within 1–2 mm of the VIN/VOUT pins on each channel to ensure stability and minimize high-frequency impedance. The exposed thermal pad (DAP) of the WSON-6 package must be soldered to a continuous top-layer ground pour with multiple thermal vias to a mid-layer ground plane. This provides the lowest thermal resistance (θJA) path and is required to sustain the 200 mA per-channel rating without derating.
Estimated: at VIN = 5 V, VOUT = 2.8 V, and IOUT = 200 mA per channel, each channel dissipates approximately (5 V − 2.8 V) × 0.2 A = 0.44 W, and both channels combined approach 0.9 W. With a typical WSON-6 θJA of ~70 °C/W on a 1-oz copper pour, junction temperature rise is ~63 °C above ambient. At 85 °C ambient, this keeps TJ near 148 °C, so derating or a larger copper pour is recommended for sustained full-load operation in enclosed automotive modules.
Do not populate the output capacitor with values smaller than 1 µF or use Y5V dielectrics — the TLV710-Q1 family requires X5R/X7R ceramics to remain stable across temperature and DC bias. Verify EN logic polarity: both EN pins are active-high; leaving them floating disables the corresponding output. Also ensure the VIN trace can source 200 mA per channel without significant IR drop, since shared input impedance between the two channels can cause channel-to-channel cross-talk under fast load transients.
