Product details
Overview
TPS71828-30DRVT from Texas Instruments is a dual-output, 200mA low-noise LDO regulator with independent enables, delivering fixed 2.8V on OUT1 and 3.0V on OUT2. It operates from 2.7V to 6.5V input, achieves 230mV dropout at 200mA, and maintains ±3% output accuracy over –40°C to +125°C for portable power rails in camera modules and WLAN basebands.
For engineers reviewing the TPS71828-30DRVT datasheet, TPS71828-30DRVT pinout, TPS71828-30DRVT application, or TPS71828-30DRVT equivalent, key selection criteria include dual-rail sequencing capability, 70µVRMS noise performance, 65dB PSRR at 1kHz, and compatibility with 1µF ceramic output capacitors in space-constrained 2mm × 2mm SON-6 packages.
Technical Context
The TPS71828-30DRVT integrates two independent PMOS-based LDOs sharing a common IN and GND, each with dedicated EN1/EN2 control pins enabling precise power sequencing. Its sub-bandgap reference and BiCMOS process ensure stable regulation down to zero load while maintaining 90µA total quiescent current with both outputs enabled.
Each regulator features internal over-current, thermal shutdown, and undervoltage lockout (UVLO) with 2.45V turn-on threshold and 150mV hysteresis. Dropout voltage scales linearly with load due to RDS(ON) behavior of the PMOS pass element, and the device remains stable without minimum load requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltages | 2.8V (OUT1) and 3.0V (OUT2), factory-programmed via EEPROM - eliminates external feedback resistors and ensures tight initial accuracy. |
| Max output current | 200mA per channel - supports dual-core processors or image sensor + interface IC combinations in handheld devices. |
| Dropout voltage | 230mV at 200mA - enables operation from single-cell Li-ion (3.0V min) while sustaining full load on both rails. |
| Output noise | 70µVRMS (BW: 100Hz–100kHz) - meets stringent analog supply requirements for ADCs, RF synthesizers, and camera ISPs. |
| PSRR | 65dB at 1kHz, 44dB at 1MHz - suppresses switching noise from upstream DC/DC converters in mixed-signal systems. |
| Enable thresholds | VEN(HI) = 1.25V min, VEN(LO) = 0.4V max - compatible with 1.8V/3.3V GPIOs and supports flexible power-up sequencing. |
| Operating temperature | –40°C to +125°C junction - qualified for automotive infotainment and industrial edge computing applications. |
Pinout & Package
TPS71828-30DRVT uses the DRV package: 2mm × 2mm WSON-6 (SON-6) with exposed thermal pad connected to GND. Pin 1 is marked by chamfered corner; top view orientation matches TI standard DRV pinout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1 | Regulator 1 output | Supplies 2.8V rail; requires ≥1µF ceramic capacitor to GND for stability and transient response. |
| IN | Input supply | Common input for both LDOs; accepts 2.7V–6.5V; benefits from local 0.1–1.0µF low-ESR decoupling. |
| OUT2 | Regulator 2 output | Supplies 3.0V rail; independently regulated and sequenced via EN2; same capacitor requirement as OUT1. |
| EN2 | Enable for OUT2 | Active-high logic input; drives high (>1.25V) to enable 3.0V rail; pulls low (<0.4V) for shutdown and <3µA quiescent draw. |
| GND | Ground reference | Common return for both regulators and enable inputs; thermal pad must be soldered to PCB ground plane for thermal reliability. |
| EN1 | Enable for OUT1 | Active-high logic input; controls 2.8V rail independently; enables asymmetric power sequencing (e.g., sensor before ISP). |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enables | EN1 and EN2 allow staggered startup/shutdown - critical for avoiding backfeed, meeting SoC power sequencing specs, and reducing inrush current. |
| Ultra-low noise | 70µVRMS output noise enables clean analog supply for high-resolution image sensors and RF front-ends without additional filtering. |
| Stable with 1µF ceramic | Eliminates need for large tantalum or aluminum electrolytics - reduces board area, cost, and improves reliability in portable designs. |
| Low quiescent current | 90µA total with both LDOs enabled - extends battery life in always-on camera modules and Bluetooth LE peripherals. |
| Thermal & fault protection | Integrated thermal shutdown (+160°C trip), over-current limit (~240–575mA), and UVLO prevent damage during overload or input brownout. |
Applications
| Mobile Camera Module | WLAN Baseband Power |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS71828-33DRVT | Same DRV package and pinout; outputs 2.8V/3.3V instead of 2.8V/3.0V - higher second rail voltage. | Suitable when downstream logic requires 3.3V I/O tolerance rather than 3.0V core voltage. | Select if system-level voltage margin allows 3.3V on OUT2; verify load compatibility with increased VOUT2. |
| TPS71928-30DRVT | Includes active output pulldown circuit on both channels - discharges outputs rapidly during shutdown (180µs). | Required where fast discharge prevents latch-up or meets strict power-down timing in USB-powered devices. | Choose only if active pulldown is mandatory; TPS71828-30DRVT lacks this feature and relies on external pulldowns. |
Compared with TPS71828-30DRVT, TPS71828-33DRVT offers higher second-rail voltage for legacy 3.3V interfaces, while TPS71928-30DRVT adds active pulldown for faster discharge - neither is pin-compatible drop-in replacements, but both share identical DRV footprint and enable logic.

FAQ
What are the exact output voltages of the TPS71828-30DRVT?
The TPS71828-30DRVT delivers precisely 2.8V on OUT1 and 3.0V on OUT2. These values are factory-programmed into internal EEPROM during wafer test and are guaranteed within ±3% over line, load, process, and temperature (–40°C to +125°C). No external resistors are required to set these outputs.
Does the TPS71828-30DRVT require an external pull-down resistor on EN1 or EN2?
No, the TPS71828-30DRVT does not require external pull-down resistors on EN1 or EN2. Each enable pin has internal leakage-limited shutdown current (≤3.0µA at –40°C to +85°C), and the device enters low-IQ shutdown state when either EN pin is held ≤0.4V. External resistors are unnecessary unless specific timing or noise immunity is needed.
Can the TPS71828-30DRVT operate with only one output enabled?
Yes, the TPS71828-30DRVT supports independent operation: EN1 can enable only OUT1 (2.8V) while EN2 holds OUT2 (3.0V) disabled, or vice versa. Total ground current drops to ~30µA in single-output active mode, making it ideal for partial-power-down states in battery-powered systems.
Is the TPS71828-30DRVT stable with 1µF ceramic capacitors on both outputs?
Yes, the TPS71828-30DRVT is fully characterized and stable with ≥1.0µF X5R/X7R ceramic capacitors on OUT1 and OUT2. TI specifies ESR <1.0Ω; typical 0603/0805 1µF ceramics meet this, eliminating need for larger or higher-ESR types and simplifying layout.
What thermal derating applies to the TPS71828-30DRVT in a standard JEDEC High-K board?
On a JEDEC High-K board (3″×3″, 2-oz copper, internal planes), the TPS71828-30DRVT (DRV package) has RθJA = 95°C/W. At +70°C ambient, maximum continuous power dissipation is 579mW - corresponding to ~200mA load at 2.8V output with 3.8V input (ΔV = 1.0V). Derating is 10.53mW/°C above +25°C ambient.
