Texas Instruments TPS780230300DRVR

Overview

TPS780230300DRVR from Texas Instruments is a 150-mA ultralow-power LDO regulator with pin-selectable dual-level output voltage (2.3 V and 3.0 V), 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 capacitor. It enables dynamic voltage scaling in battery-powered microcontroller systems such as MSP430-based sensor nodes.

For engineers reviewing the TPS780230300DRVR datasheet, TPS780230300DRVR pinout, TPS780230300DRVR application, or TPS780230300DRVR equivalent, key selection criteria include dual-voltage DVS capability, sub-1-μA shutdown current (18 nA typical), CMOS-compatible enable logic, thermal shutdown protection, and SON-6 package compatibility with space-constrained portable designs.

Technical Context

The TPS780230300DRVR implements factory-programmed EPROM-stored dual output voltages (2.3 V and 3.0 V) selected via the VSET pin: low-level input (≤0.4 V) selects 3.0 V output, high-level input (≥1.2 V) selects 2.3 V output. Its internal bandgap reference and PMOS pass transistor deliver stable regulation across –40°C to +125°C junction temperature.

It features integrated thermal shutdown (trip at 160°C, reset at 140°C) and current limiting (230 mA typical), with no external components required for stability. The EN pin supports standard CMOS logic thresholds (enable ≥1.2 V, disable ≤0.4 V), and ground pin current remains ≤5 μA at full 150 mA load.

FAQ

What are the exact factory-programmed output voltages for TPS780230300DRVR?

The TPS780230300DRVR is factory-programmed with two precise output voltages: 2.3 V (selected when VSET ≥1.2 V) and 3.0 V (selected when VSET ≤0.4 V). These values are verified across –40°C to +125°C and 0–150 mA load, with ±3% total accuracy including line, load, and temperature effects. The TPS780230300DRVR datasheet specifies these as nominal values with no user-adjustment capability.

How does the VSET pin toggle between the two output voltages on TPS780230300DRVR?

The VSET pin on TPS780230300DRVR toggles output voltage based on logic threshold: driving VSET ≤0.4 V selects the high-level output (3.0 V), while driving VSET ≥1.2 V selects the low-level output (2.3 V). The transition is monotonic with no hysteresis, and VSET draws only 70 nA maximum-enabling direct connection to GPIO pins of MSP430 or other low-power MCUs without additional drivers.

What is the minimum input voltage required for TPS780230300DRVR to regulate at 3.0 V output?

To maintain regulation at 3.0 V output, TPS780230300DRVR requires VIN ≥3.2 V under full 150 mA load (based on 200 mV dropout specification). At lighter loads, regulation is maintained down to VIN = 3.05 V (50 mV dropout). The absolute minimum recommended input is 2.2 V per datasheet, but below 3.2 V the device cannot sustain 3.0 V output at rated current-TPS780230300DRVR will drop out of regulation.

Can TPS780230300DRVR be used without an input capacitor?

No-TPS780230300DRVR requires a 1.0-μF ceramic capacitor from IN to GND, placed as close as possible to the pin. Omitting this capacitor degrades PSRR (especially above 10 kHz), increases susceptibility to input ripple, and risks instability during load transients. The TPS780230300DRVR datasheet explicitly states "a typical input capacitor is 1.0 μF" and confirms stability is guaranteed only with ≥1.0 μF ceramic at IN.

Does TPS780230300DRVR support reverse current blocking?

Yes-TPS780230300DRVR incorporates reverse current blocking via its PMOS pass transistor architecture. When VIN falls below VOUT, the body diode is reverse-biased and no significant reverse current flows from OUT to IN. This protects upstream sources (e.g., batteries or chargers) and prevents backfeeding, a critical feature for systems with multiple power domains or hot-swap capability.
