Texas Instruments TPS728120150DRVT

Overview

TPS728120150DRVT from Texas Instruments is a 200mA low-dropout linear regulator with pin-selectable dual-output voltages (1.20V and 1.50V), 230mV typical dropout at full load, ±3% output accuracy over load/line/temperature, and stable operation with only 1.0μF ceramic output capacitance. It serves as a power management IC in battery-powered handheld devices requiring dynamic voltage scaling.

For engineers reviewing the TPS728120150DRVT datasheet, TPS728120150DRVT pinout, TPS728120150DRVT application, or TPS728120150DRVT equivalent, key selection criteria include dual-voltage toggle timing (<40μs), ultra-low quiescent current (50μA), thermal shutdown behavior (+160°C trip), PSRR performance (65dB @ 1kHz), and compatibility with nanoscale processor leakage reduction schemes.

Technical Context

The TPS728120150DRVT employs a PMOS pass transistor architecture enabling low dropout and inherent reverse-current blocking. Its EEPROM-programmed dual-output configuration is selected via the VSET pin, which toggles between factory-set 1.20V (VSET = low) and 1.50V (VSET = high) outputs without external resistors.

Internal circuitry includes active pulldown for fast output discharge during shutdown, undervoltage lockout (UVLO) with 2.38–2.65V activation threshold and 230mV hysteresis, and thermal shutdown with +160°C trip and +140°C reset. It operates across –40°C to +125°C junction temperature and supports input voltages from 2.7V to 6.5V.

Key Specifications

Pinout & Package

TPS728120150DRVT is housed in a 2mm × 2mm SON-6 package (DRV) with exposed thermal pad. The thermal pad must be connected to GND for optimal thermal performance and electrical stability.

FAQ

What output voltages does the TPS728120150DRVT support?

The TPS728120150DRVT delivers two factory-programmed, EEPROM-set output voltages: 1.20V when the VSET pin is driven below 0.4V, and 1.50V when VSET is driven above 1.2V. These values are fixed per device ordering code and cannot be altered in-circuit.

How does the TPS728120150DRVT handle thermal overload?

The TPS728120150DRVT integrates thermal shutdown that disables the output when junction temperature reaches approximately +160°C. Output resumes automatically once the die cools to +140°C. Continuous cycling indicates excessive power dissipation or inadequate PCB copper area.

Can the TPS728120150DRVT operate without an output capacitor?

No-the TPS728120150DRVT requires a minimum 1.0μF ceramic capacitor (X5R or X7R dielectric) from OUT to GND for stability. Omitting it causes oscillation and violates the device's AC performance specifications, including PSRR and transient response.

What is the minimum input voltage required for the TPS728120150DRVT to regulate at 1.50V?

To maintain regulation at 1.50V output, the TPS728120150DRVT requires VIN ≥ VOUT + VDO = 1.50V + 0.23V = 1.73V minimum. However, absolute minimum VIN is specified as 2.7V per datasheet-so actual minimum usable input is 2.7V regardless of dropout.

Is the TPS728120150DRVT compatible with lead-free PCB assembly processes?

Yes-the TPS728120150DRVT uses CU NIPDAU lead-free finish and is rated for MSL Level-1 at 260°C, making it fully compatible with standard lead-free reflow profiles. The DRV package's thermal pad must be soldered to a GND plane per TI's recommended footprint.
