Product details
Overview
TLV7162818PDPQR from Texas Instruments is a capacitor-free, dual-channel, 150-mA low-dropout (LDO) voltage regulator in a 1.2-mm × 1.2-mm X2SON-6 (DPQ) package. It delivers fixed 2.8 V and 1.8 V outputs with ±1.5% accuracy over –40°C to 125°C, supports 1.4 V to 5.5 V input, and features independent enable pins (EN1/EN2) for power sequencing in portable battery-powered systems.
For engineers reviewing the TLV7162818PDPQR datasheet, TLV7162818PDPQR pinout, TLV7162818PDPQR application, or TLV7162818PDPQR equivalent, key selection criteria include dual-rail output stability without external capacitors, inrush current control during startup, low crosstalk between channels, thermal shutdown at 158°C, and pulldown capability on both outputs for fast discharge.
Technical Context
The TLV7162818PDPQR integrates two independent PMOS-based LDO regulators with separate enable inputs and shared ground. Each channel uses an internal bandgap reference and error amplifier to maintain regulation across load (0–150 mA), line (1.4–5.5 V), and temperature (–40°C to 125°C) variations.
It employs foldback current limiting and thermal shutdown (trip at 158°C, reset at 140°C) for fault protection. The TLV716P variant-confirmed by the 'P' suffix and RPD = 120 Ω specification-adds active pulldown circuitry on both OUT1 and OUT2 to rapidly discharge outputs during disable, unlike standard TLV716.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltages | Fixed 2.8 V and 1.8 V - eliminates need for external feedback resistors and ensures stable dual-rail biasing for RF ICs and processors. |
| Accuracy | ±1.5% over –40°C to 125°C - guarantees consistent voltage delivery under full industrial temperature range without calibration. |
| Input voltage range | 1.4 V to 5.5 V - supports single-cell Li-ion (3.0–4.2 V), USB (5 V), and legacy 3.3 V/2.5 V rails without external pre-regulation. |
| Max output current | 150 mA per channel - sufficient to power baseband processors, RF transceivers, and sensor interfaces in compact handheld devices. |
| Dropout voltage | 0.29 V at 150 mA (2.8 V output) - enables operation with minimal headroom, extending battery runtime in low-VIN conditions. |
| PSRR | 80 dB at 100 Hz, 46 dB at 10 kHz - suppresses supply noise from noisy DC-DC converters feeding sensitive analog/RF circuits. |
| Output noise | 70 µVRMS (10 Hz–100 kHz) - meets low-noise requirements for ADC references, PLL VCO supplies, and audio codecs. |
Pinout & Package
TLV7162818PDPQR is housed in a 1.2-mm × 1.2-mm, 6-pin X2SON (DPQ) package with exposed thermal pad. The small footprint and low profile (0.4 mm height) support ultra-thin mobile designs and high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1 | Regulated 2.8 V output | Supplies primary rail (e.g., RF transceiver core); stable without output capacitor; pulldown enabled when EN1 < 0.4 V. |
| OUT2 | Regulated 1.8 V output | Supplies secondary rail (e.g., digital I/O or memory interface); independent regulation and pulldown control via EN2. |
| GND | Power ground reference | Common return path for both regulators; thermal pad must be soldered to PCB ground plane for RθJB = 110.1°C/W. |
| EN2 | Enable input for OUT2 | Active-high logic: ≥0.9 V enables 1.8 V rail; <0.4 V disables and activates 120 Ω pulldown to discharge OUT2. |
| IN | Input voltage supply | Accepts 1.4–5.5 V; no input capacitor required, but 0.1–1 µF ceramic improves PSRR and transient response. |
| EN1 | Enable input for OUT1 | Active-high logic: ≥0.9 V enables 2.8 V rail; <0.4 V disables and activates 120 Ω pulldown to discharge OUT1. |
Key Features
| Feature | Design Value |
|---|---|
| No input or output capacitors required | Enables BOM reduction and board space savings in size-constrained applications like wearables and IoT sensors. |
| Inrush current control | Provides constant-current startup charging to prevent input overcurrent faults during simultaneous rail enablement. |
| Low crosstalk (<0.066 mV/mA) | Minimizes interference between rails-critical when powering noise-sensitive RF and digital subsystems from same source. |
| Active pulldown (120 Ω) | Ensures rapid, controlled discharge of both outputs during shutdown-prevents floating nodes and latch-up in downstream logic. |
| Foldback current limit | Reduces output current as VOUT drops during overload, limiting power dissipation and enabling safe thermal recovery. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC7528IPW | Single 8-bit DAC with parallel interface; not a voltage regulator - functionally incompatible. | N/A - does not perform voltage regulation or power management. | Not suitable as a replacement; misidentified part number. |
| TPS7A202818PDBVR | Capacitor-free dual LDO with same 2.8 V/1.8 V outputs, but uses SOT-23-8 package (2.9 mm × 1.6 mm) and lacks pulldown circuitry. | Requires larger PCB area and cannot actively discharge outputs - unsuitable where fast rail collapse is mandatory. | Select TLV7162818PDPQR when board space is constrained and active pulldown is required for system-level power sequencing. |

FAQ
What is the dropout voltage of TLV7162818PDPQR at full load?
The dropout voltage of TLV7162818PDPQR is 0.29 V at 150 mA for the 2.8 V output and 0.23 V at 150 mA for the 1.8 V output, measured under TJ = 25°C with VIN = VOUT(TYP) + 0.5 V. These values scale with load current and temperature, remaining within datasheet-specified limits up to 125°C junction temperature. TLV7162818PDPQR maintains regulation down to these minimum headroom conditions.
Does TLV7162818PDPQR require input or output capacitors to operate?
No, TLV7162818PDPQR is explicitly designed for capacitor-free operation-both input and output capacitors are optional. Stability is guaranteed without them due to its advanced internal control loop. However, adding a 0.1–1 µF ceramic input capacitor improves PSRR and transient response, and a ≥0.1 µF output capacitor enhances dynamic performance. TLV7162818PDPQR remains fully functional and specified even with zero external capacitance.
How does the pulldown feature work on TLV7162818PDPQR?
The 'P' suffix in TLV7162818PDPQR denotes the pulldown variant: when either EN1 or EN2 falls below 0.4 V, the corresponding output (OUT1 or OUT2) is actively discharged through an internal 120 Ω resistor to GND. This ensures rapid, controlled rail collapse-critical for preventing floating nodes, reducing leakage, and meeting system-level power sequencing requirements. Standard TLV716 parts lack this feature.
What is the accuracy specification of TLV7162818PDPQR over temperature?
TLV7162818PDPQR guarantees ±1.5% output voltage accuracy over the full operating junction temperature range of –40°C to 125°C for both 2.8 V and 1.8 V outputs. At 25°C, typical accuracy is ±0.33%. This specification includes initial tolerance, line regulation, load regulation, and temperature drift-ensuring reliable performance in automotive cabin and industrial environments without recalibration.
Can TLV7162818PDPQR be used with lithium-ion battery input?
Yes, TLV7162818PDPQR supports input voltages from 1.4 V to 5.5 V, making it compatible with single-cell Li-ion batteries (nominal 3.7 V, range 3.0–4.2 V). Its low dropout (0.23–0.29 V) maximizes usable battery capacity, and inrush current control prevents overcurrent faults during cold-start. The device operates reliably across the full battery discharge curve, including end-of-life voltage sag, while maintaining ±1.5% accuracy up to 125°C junction temperature. TLV7162818PDPQR is validated for this use case in TI's typical application circuits.
