Texas Instruments TPS780180300DRVR

Overview

TPS780180300DRVR from Texas Instruments is a dual-level fixed-output LDO regulator delivering 1.8 V (low) and 3.0 V (high) with ultralow 500 nA quiescent current, 200 mV dropout at 150 mA, ±3% output accuracy over load/line/temperature, and stable operation with 1.0-μF ceramic output capacitance. It enables dynamic voltage scaling in MSP430-based battery-powered systems for sleep/wake power optimization.

For engineers reviewing the TPS780180300DRVR datasheet, TPS780180300DRVR pinout, TPS780180300DRVR application, or TPS780180300DRVR equivalent, key selection criteria include dual-voltage toggle via VSET pin, shutdown current of 18 nA, thermal shutdown at 160°C, CMOS-compatible EN pin, and DRV (2-mm × 2-mm SON-6) package compatibility with space-constrained portable designs.

Technical Context

The TPS780180300DRVR implements factory-programmed dual output voltages (1.8 V and 3.0 V) selected by logic level on the VSET pin: ≤0.4 V selects 1.8 V, ≥1.2 V selects 3.0 V. Its internal EPROM stores voltage levels, eliminating external resistors or configuration pins.

It features a CMOS-compatible enable input (EN), thermal shutdown (160°C trip, 140°C reset), foldback current limiting (150–400 mA), and operates across –40°C to +125°C junction temperature. Input voltage range is 2.2 V to 5.5 V; output current capability is rated up to 150 mA continuous.

FAQ

What are the factory-programmed output voltages of the TPS780180300DRVR?

The TPS780180300DRVR is factory-programmed with two fixed output voltages: 1.8 V (selected when VSET ≤ 0.4 V) and 3.0 V (selected when VSET ≥ 1.2 V). These values are permanently stored in on-chip EPROM and cannot be altered in the field. The TPS780180300DRVR datasheet confirms ±3% accuracy across temperature, load, and line conditions for both levels.

How does the VSET pin toggle between output voltages on the TPS780180300DRVR?

The VSET pin on the TPS780180300DRVR acts as a logic-select input: driving it to ≤0.4 V selects the low output (1.8 V), while driving it to ≥1.2 V selects the high output (3.0 V). The transition threshold has built-in hysteresis to prevent oscillation during slow-ramp signals. This toggle occurs within 800 μs, as measured in the TPS780180300DRVR electrical characteristics table.

What is the minimum input voltage required for the TPS780180300DRVR to regulate at 3.0 V output?

To maintain regulation at 3.0 V output, the TPS780180300DRVR requires VIN ≥ 3.25 V under 150 mA load, based on its 250 mV dropout voltage specification. At lighter loads (e.g., 10 mA), dropout drops to ~100 mV, allowing regulation down to ~3.1 V input. The absolute minimum input voltage is 2.2 V, but that only supports regulation to 1.8 V output.

Can the TPS780180300DRVR be used without an output capacitor?

No-the TPS780180300DRVR requires a minimum 1.0-μF ceramic capacitor from OUT to GND for stability, as explicitly stated in the datasheet's "Stable with a 1.0-μF Ceramic Capacitor" feature and "Input and Output Capacitor Requirements" section. Omitting this capacitor risks oscillation, poor transient response, and potential damage during load steps.

Is the TPS780180300DRVR pin-compatible with other TPS780 variants in the DRV package?

Yes-the TPS780180300DRVR shares identical pinout, package dimensions, and thermal pad configuration with all DRV-packaged TPS780xx devices (e.g., TPS780180280DRVR, TPS780280330DRVR). All use Pin 1=IN, Pin 2=GND, Pin 3=EN, Pin 4=VSET/FB, Pin 5=OUT, Pin 6=NC. This enables drop-in replacement across dual-output variants without PCB revision.
