Product details
Overview
TPS728100180DRVR from Texas Instruments is a 200mA low-dropout linear regulator with pin-selectable dual-output voltages (1.00V and 1.80V), 230mV typical dropout at full load, ±3% output accuracy over load/line/temperature, 50μA quiescent current, and stable operation with 1.0μF ceramic output capacitance. It serves as a power rail controller in mobile memory interfaces requiring dynamic voltage scaling.
For engineers reviewing the TPS728100180DRVR datasheet, TPS728100180DRVR pinout, TPS728100180DRVR application, or TPS728100180DRVR equivalent, key selection criteria include dual-voltage toggle timing (<40μs), thermal shutdown threshold (+160°C), PSRR (65dB @ 1kHz), UVLO hysteresis (230mV), and compatibility with nanometric process leakage reduction.
Technical Context
The TPS728100180DRVR implements a PMOS pass transistor architecture with factory-programmed EEPROM to fix two output voltage levels (VOUT1 = 1.00V, VOUT2 = 1.80V). Its VSET pin toggles between these levels using TTL/CMOS-compatible logic thresholds (VLO ≤ 0.4V, VHI ≥ 1.2V).
It integrates active pulldown for fast output discharge during shutdown, undervoltage lockout with 230mV hysteresis, and thermal shutdown with +140°C reset and +160°C trip. The device operates across –40°C to +125°C junction temperature and supports input voltages from 2.7V to 6.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 200mA maximum continuous; internally current-limited to 240–575mA for fault protection |
| Dropout Voltage | 230mV typical at 200mA; enables regulation down to VIN = VOUT + 0.23V |
| Output Accuracy | ±3% over load, line, and temperature; ensures stable core/memory rail compliance |
| Quiescent Current | 50μA in active mode; reduces standby power in always-on subsystems |
| PSRR | 65dB at 1kHz; suppresses switching noise from upstream DC/DC converters |
| Startup Time | 160μs to 97% of nominal output; supports fast wake-up in low-power states |
| Shutdown Current | 0.10–1.0μA; enables ultra-low leakage during deep sleep modes |
Pinout & Package
TPS728100180DRVR uses the DRV package: 2mm × 2mm WSON-6 with exposed thermal pad (pin 6). The thermal pad must be connected to GND for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input supply connection | Accepts 2.7V–6.5V input; requires local 0.1–1.0μF ceramic decoupling |
| 2 - EN | Enable control input | Active-high TTL/CMOS compatible; <0.4V disables regulator, >1.2V enables |
| 3 - NC | No-connect terminal | Not bonded; must remain unconnected on PCB |
| 4 - OUT | Regulated output | Delivers 1.00V or 1.80V depending on VSET state; requires 1.0μF ceramic capacitor to GND |
| 5 - VSET | Voltage select control | Drives low (≤0.4V) for 1.00V output, high (≥1.2V) for 1.80V output |
| 6 - GND | Power and signal ground | Reference for all pins; thermal pad (underside) must be soldered to GND plane |
Key Features
| Feature | Design Value |
|---|---|
| Dual-pin-selectable output | VSET pin toggles between factory-programmed 1.00V and 1.80V outputs in <40μs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS728180285YZUR | WCSP-5 package (1.2mm × 0.8mm), 1.80V/2.85V outputs, no NC pin | Targeted for space-constrained wearables; lacks thermal pad and requires tighter layout control | Select when board area <1.0mm² is critical and 2.85V second rail is acceptable |
| TPS728120150DRVR | Same DRV package, 1.20V/1.50V dual outputs, identical pinout and specs except VOUT values | Suitable for I/O voltage translation (1.2V core + 1.5V interface) rather than memory DVS | Choose when system requires 1.2V/1.5V rails and maintains same PCB footprint and thermal design |
Compared with TPS728100180DRVR, the YZUR variant trades thermal performance and ease of assembly for extreme miniaturization, while the DRVR-based 120150 offers different voltage pairing for non-memory use cases-neither is pin-compatible nor drop-in replaceable without schematic and layout revision.

FAQ
What are the exact factory-programmed output voltages for TPS728100180DRVR?
The TPS728100180DRVR is factory-programmed with two precise output voltages: VOUT1 = 1.00V (selected when VSET ≤ 0.4V) and VOUT2 = 1.80V (selected when VSET ≥ 1.2V). These values are laser-trimmed and EEPROM-stored during manufacturing-no external resistors or configuration required. Each unit ships with guaranteed 1.00V/1.80V pairing verified per SBVS095 datasheet Section 6.5.
Can TPS728100180DRVR operate with input voltage below 2.7V?
No. The absolute minimum input voltage for TPS728100180DRVR is 2.7V, as specified in the Absolute Maximum Ratings table and confirmed in Electrical Characteristics test conditions. Operation below 2.7V violates the VIN specification and may cause UVLO activation or unstable regulation. For sub-2.7V applications, TI recommends the TPS7A05 or TPS7A16 families.
Is the NC pin on TPS728100180DRVR required to be grounded or left floating?
The NC pin (Pin 3) on TPS728100180DRVR is not internally connected and must remain unconnected-neither grounded nor tied to any net. Per TI's Pin Descriptions table and Package Drawing SBVS095, this terminal is unused and bonding is omitted. Connecting it risks unintended parasitic paths or ESD vulnerability.
Does TPS728100180DRVR require an input capacitor for stability?
An input capacitor is not required for stability of TPS728100180DRVR, but TI strongly recommends a 0.1μF–1.0μF ceramic capacitor placed near the IN pin to improve transient response, noise rejection, and ripple suppression-especially when source impedance is high or the device is remote from the power source. This practice is detailed in Section 9.2.1 of the datasheet.
What is the thermal pad connection requirement for TPS728100180DRVR?
The thermal pad on the underside of the TPS728100180DRVR DRV package (exposed copper area) must be soldered directly to a PCB GND plane. TI specifies this in the Pin Descriptions table and Figure 42 notes: "It is recommended that the SON package thermal pad be connected to ground." Omitting this connection degrades thermal resistance by >40°C/W and risks thermal shutdown under 200mA load.
