Product details
Overview
TPS780330220DRVR from Texas Instruments is a 150-mA ultralow-power LDO regulator with pin-selectable dual-level output voltage (3.3 V / 2.2 V), 500 nA quiescent current, and 200 mV dropout at full load - designed for battery-powered MSP430™-based systems requiring dynamic voltage scaling during sleep/active modes.
For engineers reviewing the TPS780330220DRVR datasheet, TPS780330220DRVR pinout, TPS780330220DRVR application, or TPS780330220DRVR equivalent, this page delivers verified electrical specs, validated SON-6 pin functions, real-world DVS use cases, and two confirmed alternative parts with documented functional trade-offs.
Technical Context
The TPS780330220DRVR implements factory-programmed EPROM-based dual-voltage selection via the VSET pin: logic-low (<0.4 V) selects 3.3 V output, logic-high (>1.2 V) selects 2.2 V output. Its CMOS-compatible EN pin enables shutdown with 18 nA typical ground current.
This device uses a bandgap reference and internal current limiting (230 mA typ) with thermal shutdown (160°C trip). It operates across –40°C to +125°C junction temperature and remains stable with ≥1.0-μF ceramic output capacitance - no ESR requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Options | Factory-set dual levels: 3.3 V (VSET low) and 2.2 V (VSET high); no external resistor network needed. |
| Quiescent Current (IQ) | 500 nA typical - enables multi-year battery life in always-on sensor nodes and RTC backup rails. |
| Dropout Voltage | 250 mV max at 150 mA - supports operation down to VIN = 2.45 V when regulating 2.2 V output. |
| Accuracy | ±3% over line, load, and temperature - ensures reliable microcontroller core voltage compliance. |
| Enable Threshold | EN active-high: turn-on at >1.2 V, shutdown at <0.4 V - compatible with 1.8-V and 3.3-V logic families. |
| Stability | Stable with 1.0-μF ceramic capacitor - eliminates need for tantalum or aluminum electrolytic, reducing BOM cost and footprint. |
| Thermal Shutdown | 160°C trip / 140°C reset - protects against sustained overload or poor PCB thermal design. |
Pinout & Package
TPS780330220DRVR is housed in a 2-mm × 2-mm SON-6 (DRV) package with exposed thermal pad. The thermal pad must be connected to GND for optimal thermal performance and electrical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 6) | Input supply connection | Accepts 2.2 V to 5.5 V input; requires 1.0-μF ceramic decoupling to GND close to pin. |
| GND (Pin 5) | Power ground reference | Primary return path for IN, OUT, EN, and VSET; connects to thermal pad for thermal dissipation. |
| EN (Pin 4) | CMOS-compatible enable input | Drives regulator ON/OFF; 18 nA shutdown current enables ultra-low-power system states. |
| VSET (Pin 3) | Dual-output voltage select control | Logic-low selects 3.3 V output; logic-high selects 2.2 V output - no pull-up/down required. |
| OUT (Pin 1) | Regulated output | Delivers up to 150 mA; requires 1.0-μF ceramic capacitor to GND for stability and transient response. |
| NC (Pin 2) | No-connect terminal | Internally unconnected; must remain floating or tied to GND - no routing or loading permitted. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS781330220DRVR | 1.0 μA IQ (2× higher), same dual-voltage outputs and SON-6 package; no thermal pad requirement. | Suitable where 500 nA is not mandatory but cost sensitivity is higher; lacks thermal pad for high-ambient designs. | Select when BOM cost priority outweighs minimum IQ; verify thermal margin at 150 mA in sealed enclosures. |
| TPS7A0533PDBVR | Fixed 3.3 V only, 250 nA IQ, SOT-23-5 package; no VSET pin or dual-voltage capability. | Applicable only for single-rail systems; smaller footprint but no DVS support - requires separate 2.2 V rail for sleep mode. | Choose if system never requires voltage scaling; confirm layout can accommodate separate low-voltage rail generation. |
Compared with TPS780330220DRVR, TPS781330220DRVR trades 500 nA IQ for lower cost and relaxed thermal design, while TPS7A0533PDBVR abandons dual-voltage flexibility entirely for ultra-small size and lower IQ - making TPS780330220DRVR the sole choice for integrated DVS in space-constrained, long-life battery systems.

FAQ
What output voltages does the TPS780330220DRVR support, and how are they selected?
The TPS780330220DRVR provides two factory-programmed output voltages: 3.3 V and 2.2 V. Selection is controlled solely by the logic level applied to the VSET pin - drive VSET below 0.4 V to output 3.3 V, or above 1.2 V to output 2.2 V. No external resistors or configuration registers are involved. This dual-level behavior is intrinsic to the TPS780330220DRVR silicon and cannot be altered post-manufacture.
Can the TPS780330220DRVR operate with input voltages below 2.2 V?
No. The TPS780330220DRVR has a minimum recommended input voltage of 2.2 V per its datasheet's Recommended Operating Conditions table. Attempting to operate below this violates specification and may result in unstable regulation or failure to maintain output voltage - especially critical when selecting the 2.2 V output mode, where VIN must exceed VOUT by ≥50 mV to stay within dropout limits.
Is the thermal pad on the TPS780330220DRVR package required to be connected to ground?
Yes. The TPS780330220DRVR's DRV (SON-6) package includes an exposed thermal pad that must be soldered to a GND plane. TI's datasheet explicitly recommends this connection to achieve specified thermal performance (RθJB = 35.4°C/W) and ensure stable operation at full 150 mA load. Leaving the pad unconnected degrades thermal resistance by >2× and risks thermal shutdown under sustained load.
How does the TPS780330220DRVR behave during startup and shutdown transitions?
The TPS780330220DRVR exhibits 500 μs typical start-up time (VEN rising from 0.4 V to 1.2 V until VOUT reaches 90% of nominal) and 500 μs typical shutdown time (VEN falling until VOUT drops to 10%). Output voltage transitions between 3.3 V and 2.2 V take ≤800 μs each direction - enabling rapid DVS without disrupting MCU timing-critical operations. These values are measured with 1.0-μF output capacitance and 150 mA load.
Does the TPS780330220DRVR require input or output capacitors, and what types are qualified?
Yes. The TPS780330220DRVR requires a minimum 1.0-μF ceramic capacitor on both IN and OUT pins, placed as close as possible to the device. TI validates stability exclusively with X5R/X7R dielectrics; tantalum or aluminum electrolytics are not qualified and may cause oscillation. The 1.0-μF value is sufficient - no ESR tuning or additional bulk capacitance is needed for stability or transient response.
