Product details
Overview
TPS780270200DDCR from Texas Instruments is a 150-mA ultralow-power LDO regulator with pin-selectable dual-level output voltage (2.7 V / 2.0 V), 500 nA quiescent current, ±3% output accuracy over load/line/temperature, and stable operation with 1.0-μF ceramic output capacitor. It serves as a dynamic voltage scaling (DVS) power supply for MSP430 microcontrollers in battery-powered handheld devices.
For engineers reviewing the TPS780270200DDCR datasheet, TPS780270200DDCR pinout, TPS780270200DDCR application, or TPS780270200DDCR equivalent, key selection criteria include dual-voltage toggle via VSET pin, 200-mV dropout at 150 mA, thermal shutdown protection, CMOS-compatible enable logic, and TSOT23-5 package compatibility with space-constrained portable designs.
Technical Context
The TPS780270200DDCR implements factory-programmed EPROM-based dual-output voltage selection: driving VSET < 0.4 V selects 2.0 V (LOW), while driving VSET > 1.2 V selects 2.7 V (HIGH). Its internal bandgap reference and error amplifier maintain regulation across –40°C to 125°C junction temperature.
It features active-pull-down logic on EN and VSET inputs, thermal shutdown at 160°C (trip) / 140°C (reset), and internal current limiting (150–400 mA). The device operates with input voltage from 2.2 V to 5.5 V and requires no external compensation due to inherent stability with ≥1.0-μF ceramic output capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Levels | 2.7 V (HIGH) and 2.0 V (LOW), factory-programmed, toggled via VSET pin voltage threshold |
| Quiescent Current | 500 nA typical - enables multi-year battery life in always-on sensor nodes and sleep-mode MCU applications |
| Dropout Voltage | 250 mV at 150 mA - supports regulation down to VIN = VOUT + 0.25 V, critical for low-VIN battery discharge |
| Output Accuracy | ±3% over load (0–150 mA), line (2.2–5.5 V), and temperature (–40°C to 125°C) - ensures reliable MCU core voltage margin |
| Enable Threshold | VEN > 1.2 V enables regulation; VEN < 0.4 V forces shutdown with 18 nA ground current - compatible with standard CMOS logic |
| Stability | Stable with ≥1.0-μF ceramic output capacitor - eliminates need for tantalum or large bulk capacitors, reducing BOM cost and footprint |
| Protection | Thermal shutdown (160°C trip), overcurrent limit (150–400 mA), and reverse-current blocking - prevents damage during fault conditions |
Pinout & Package
TPS780270200DDCR is housed in a 5-pin TSOT23-5 (DDC) package measuring 2.90 mm × 1.60 mm, with exposed thermal pad not present in this variant. Pin 1 is IN; Pin 2 is GND; Pin 3 is EN; Pin 4 is VSET; Pin 5 is OUT.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Input voltage supply | Accepts 2.2 V to 5.5 V; requires 1.0-μF ceramic decoupling to GND near pin for stability |
| GND (Pin 2) | Ground reference | Primary return path for input/output capacitors and internal circuitry; must be low-impedance connection |
| EN (Pin 3) | Enable control input | CMOS-compatible; high (>1.2 V) enables regulator, low (<0.4 V) disables with 18 nA shutdown current |
| VSET (Pin 4) | Dual-voltage select input | Drives output to 2.7 V when >1.2 V, or 2.0 V when <0.4 V; hysteresis prevents chatter during transition |
| OUT (Pin 5) | Regulated output | Delivers up to 150 mA; requires 1.0-μF ceramic capacitor to GND for loop stability and transient response |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow IQ | 500 nA quiescent current enables >10-year battery life in coin-cell–powered IoT sensors |
| Dual-Level DVS | Factory-programmed 2.7 V / 2.0 V output levels reduce system power by 25–40% during MCU sleep mode |
| Minimal External Components | Stable with only two 1.0-μF ceramic capacitors - eliminates ESR requirements and simplifies layout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS780330220DDCR | Same package and architecture, but factory-programmed for 3.3 V / 2.2 V dual output instead of 2.7 V / 2.0 V | Targets higher-voltage MCU cores (e.g., MSP430FR59xx) requiring 3.3 V active rail; not suitable for 2.0–2.7 V systems | Select only if system requires 3.3 V nominal active voltage and 2.2 V sleep voltage - pinout and timing identical |
| TPS781220270DRVR | SON-6 package (2.0 mm × 2.0 mm), 1.0 μA IQ (double TPS780270200DDCR), same 2.2 V / 2.7 V dual output | Higher thermal resistance (RθJA = 65.9°C/W vs 193°C/W) but better power dissipation; suited for higher ambient or continuous-load scenarios | Choose when board space allows SON-6 and thermal performance outweighs 0.5 μA IQ penalty - not pin-compatible |
Compared with TPS780330220DDCR, the TPS780270200DDCR delivers tighter voltage matching for 2.0–2.7 V MSP430 variants, while TPS781220270DRVR trades 2× IQ for improved thermal handling and different footprint - neither is drop-in, but both serve adjacent low-power DVS use cases.

FAQ
What output voltages does the TPS780270200DDCR support, and how are they selected?
The TPS780270200DDCR supports two factory-programmed output voltages: 2.7 V (HIGH) and 2.0 V (LOW). Selection is controlled by the VSET pin: drive VSET above 1.2 V to activate 2.7 V output, or below 0.4 V to activate 2.0 V output. Hysteresis prevents oscillation during transitions. This dual-level capability is integral to the TPS780270200DDCR's dynamic voltage scaling function for MSP430 microcontrollers.
What is the minimum input voltage required for the TPS780270200DDCR to regulate at 2.7 V output?
The TPS780270200DDCR requires a minimum input voltage of 2.95 V to maintain regulation at 2.7 V output under full 150 mA load, based on its 250 mV dropout voltage specification. At lighter loads, regulation is sustained down to VIN = VOUT + dropout (e.g., 2.7 V + 0.05 V ≈ 2.75 V at 10 mA). Input voltage must remain within the absolute maximum range of –0.3 V to +6.0 V.
Can the TPS780270200DDCR operate with a 0.47-μF output capacitor?
No - the TPS780270200DDCR requires a minimum 1.0-μF ceramic output capacitor for guaranteed stability across all operating conditions. Using 0.47 μF risks oscillation, poor transient response, and potential output voltage collapse under load step changes. The datasheet explicitly specifies "stable with a 1.0-μF ceramic capacitor" as a design requirement, not a recommendation.
How does the TPS780270200DDCR behave during thermal shutdown?
When junction temperature reaches 160°C, the TPS780270200DDCR activates thermal shutdown, disabling the pass element and forcing output to fall. Regulation resumes only after temperature drops to 140°C (20°C hysteresis). During shutdown, ground current remains at 18 nA typical, preserving battery life. This behavior is fully characterized and guaranteed across –40°C to 125°C ambient.
Is the TPS780270200DDCR pin-compatible with other TPS780xx DDC variants?
Yes - all TPS780xx devices in the DDC (TSOT23-5) package share identical pinout: Pin 1 = IN, Pin 2 = GND, Pin 3 = EN, Pin 4 = VSET/FB, Pin 5 = OUT. The TPS780270200DDCR is mechanically and electrically interchangeable at the board level with other DDC-packaged TPS780 variants (e.g., TPS780330220DDCR), though output voltage programming differs per part number.
