Product details
Overview
TPS71913-28DRVT from Texas Instruments is a dual-output, 200mA low-dropout linear regulator with independent enables, delivering fixed 1.3V on OUT1 and 2.8V on OUT2. It features 70µVRMS output noise, 65dB PSRR at 1kHz, 230mV dropout at 200mA, and operates from 2.7V to 6.5V input. Designed for space-constrained portable electronics, it powers core logic and I/O rails in camera modules and WLAN subsystems.
For engineers reviewing the TPS71913-28DRVT datasheet, TPS71913-28DRVT pinout, TPS71913-28DRVT application, or TPS71913-28DRVT equivalent, key selection criteria include dual-rail sequencing capability, active pulldown on OUT2 for fast discharge, ceramic capacitor stability (≥1µF), thermal performance in 2mm × 2mm SON-6, and -40°C to +125°C operation.
Technical Context
The TPS71913-28DRVT integrates two independent PMOS-based LDOs sharing a common IN and GND, each with dedicated EN pins (EN1/EN2) enabling precise power sequencing. Its sub-bandgap reference and advanced BiCMOS process achieve ±3% output accuracy over line, load, temperature, and process variations.
It incorporates undervoltage lockout (UVLO with 2.45V threshold and 150mV hysteresis), thermal shutdown (+160°C trip), overcurrent protection, and-uniquely for the TPS719xx family-an active output pulldown circuit on OUT2 that discharges loads during shutdown, reducing residual voltage hold-up time.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltages | 1.3V (OUT1) and 2.8V (OUT2), factory-programmed via EEPROM; supports 0.9V–3.6V in 50mV steps. |
| Max output current | 200mA per channel; internal current limit protects against sustained overload (240–575mA typical). |
| Dropout voltage | 230mV at 200mA load; enables high efficiency at low VIN–VOUT headroom (e.g., 2.8V out from 3.03V input). |
| PSRR | 65dB at 1kHz, 44dB at 1MHz; suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Output noise | 70µVRMS (BW = 100Hz–100kHz); critical for noise-sensitive analog circuits like ADC references or RF bias rails. |
| Startup time | 160µs (from EN high to 95% VOUT); supports fast system wake-up in battery-powered devices. |
| Operating temp | -40°C to +125°C junction; fully specified for automotive infotainment and industrial edge computing environments. |
Pinout & Package
TPS71913-28DRVT uses the DRV package: 2mm × 2mm WSON-6 (SON-6) with exposed thermal pad. The package is RoHS-compliant, moisture sensitivity level (MSL) 1, and rated for reflow up to 260°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1 | Regulator 1 output | Delivers fixed 1.3V; requires ≥1µF ceramic capacitor to GND for stability and transient response. |
| IN | Input supply | Common input for both LDOs; accepts 2.7V–6.5V; decoupling capacitor recommended near pin. |
| OUT2 | Regulator 2 output | Delivers fixed 2.8V; includes active pulldown circuit to rapidly discharge load capacitance when disabled. |
| EN2 | Enable for OUT2 | Active-high TTL/CMOS-compatible; drives OUT2 into shutdown (≤0.4V) to reduce quiescent current to 0.3–1.8µA. |
| GND | Ground reference | Common ground for both regulators; thermal pad must be soldered to PCB ground plane for thermal management. |
| EN1 | Enable for OUT1 | Independent active-high enable; allows asymmetric power sequencing (e.g., enable 1.3V rail before 2.8V rail). |
Key Features
| Feature | Design Value |
|---|---|
| Independent dual enables | EN1 and EN2 allow precise sequencing of 1.3V and 2.8V rails-critical for FPGAs and processors requiring controlled power-up order. |
| Active output pulldown (OUT2) | Internally discharges OUT2 load capacitance during shutdown, eliminating need for external bleed resistors in camera sensor bias applications. |
| Ultra-low quiescent current | 90µA total (both LDOs enabled); extends battery life in always-on sensor nodes and wearable devices. |
| Ceramic capacitor stability | Stable with ≥1µF X5R/X7R ceramic output capacitors; eliminates cost and footprint of tantalum or aluminum electrolytic alternatives. |
| High PSRR at low headroom | Maintains >63dB PSRR at 1kHz even with VIN–VOUT = 0.5V; enables clean power delivery from noisy intermediate bus rails. |
Applications
| Mobile Camera Module Power | Wireless LAN Baseband SoC |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS71918-28DRVT | Outputs 1.8V/2.8V instead of 1.3V/2.8V; identical package, pinout, and electrical specs otherwise. | Suitable where higher core voltage is required (e.g., legacy ARM Cortex-M3/M4 MCUs). | Select when system architecture mandates 1.8V logic rail; no layout change needed. |
| TPS71813-28DRVT | Lacks active pulldown on OUT2; otherwise identical pinout, package, and output voltages (1.3V/2.8V). | Applicable where fast discharge is not required (e.g., non-critical I/O rails without sensitive analog components). | Choose for cost-sensitive designs where pulldown functionality is unnecessary; same footprint and routing. |
Compared with TPS71913-28DRVT, TPS71918-28DRVT changes only the first output voltage (1.8V vs 1.3V), while TPS71813-28DRVT removes the active pulldown feature-making the former ideal for voltage-flexible systems and the latter for simplified, lower-cost implementations without fast discharge needs.

FAQ
What are the exact output voltages of the TPS71913-28DRVT?
The TPS71913-28DRVT delivers precisely 1.3V on OUT1 and 2.8V on OUT2. These values are factory-programmed using EEPROM and are guaranteed within ±3% tolerance over temperature, line, and load conditions per the datasheet's electrical characteristics table.
Does the TPS71913-28DRVT require external components for stability?
No, the TPS71913-28DRVT is stable with only a 1.0µF ceramic capacitor on each output (OUT1 and OUT2) referenced to GND. An optional 0.1µF–1.0µF input capacitor near the IN pin improves transient response and noise rejection but is not required for stability.
How does the active pulldown feature work on the TPS71913-28DRVT?
The TPS71913-28DRVT implements active pulldown exclusively on OUT2. When EN2 is driven low, an internal NMOS transistor connects OUT2 to GND, discharging output capacitance with a time constant of t = 60 × RL × COUT. This eliminates residual voltage hold-up without external resistors.
What is the maximum allowable input voltage for the TPS71913-28DRVT?
The absolute maximum input voltage for the TPS71913-28DRVT is +7.0V, but the recommended operating range is 2.7V to 6.5V. Exceeding 6.5V may trigger internal protection or degrade long-term reliability, and operation below 2.7V risks dropout or UVLO activation.
Is the TPS71913-28DRVT pin-compatible with other devices in the TPS719xx family?
Yes, all TPS719xx devices in the DRV (WSON-6) package-including TPS71913-28DRVT-are pin-compatible. Pin assignments (OUT1, IN, OUT2, EN2, GND, EN1) and package dimensions (2mm × 2mm) are identical across the family, enabling drop-in voltage variant replacements.
