Texas Instruments TLV70015DSET

Overview

TLV70015DSET from Texas Instruments is a 200-mA, low-quiescent-current, fixed-output 1.5-V LDO linear regulator in a 1.5-mm × 1.5-mm WSON-6 package. It delivers 2% output accuracy, 43 mV dropout at 50 mA, 31 μA quiescent current, and 68 dB PSRR at 1 kHz-designed for Li-ion–powered handheld devices requiring stable, low-noise, low-power rail generation.

For engineers reviewing the TLV70015DSET datasheet, TLV70015DSET pinout, TLV70015DSET application, or TLV70015DSET equivalent, key selection criteria include dropout performance under light-to-moderate load, thermal shutdown behavior at 160°C, enable-pin logic thresholds (0.9 V high / 0.4 V low), and stability with ≥0.1 μF ceramic output capacitance.

Technical Context

The TLV70015DSET employs a PMOS pass transistor architecture enabling ultra-low dropout voltage that scales with load current-43 mV at 50 mA, 85 mV at 100 mA, and 175 mV at 200 mA under specified conditions. Its precision bandgap reference and error amplifier ensure ±2% DC accuracy across –40°C to +125°C junction temperature.

It integrates active-high enable control, undervoltage lockout (UVLO) triggering at 1.9 V, thermal shutdown (trip at 160°C, reset at 140°C), and foldback current limiting (220–860 mA). The device operates stably with output capacitors as small as 0.1 μF effective capacitance-enabling compact, bias-voltage–tolerant ceramic solutions.

Key Specifications

Pinout & Package

TLV70015DSET is housed in a thermally enhanced 6-pin WSON package (DSE), measuring 1.5 mm × 1.5 mm × 0.75 mm, with exposed thermal pad for improved PCB heat dissipation. Pin 1 is IN; Pin 2 is GND; Pin 3 is OUT; Pin 4 and Pin 5 are NC (no connection, may be tied to GND for thermal improvement); Pin 6 is EN.

FAQ

What is the minimum input voltage required for TLV70015DSET to regulate 1.5 V output?

The TLV70015DSET requires VIN ≥ VOUT + VDO. At 50 mA load, VDO = 43 mV, so minimum VIN = 1.543 V. However, per recommended operating conditions, VIN must be ≥2 V to guarantee full specification compliance-including line regulation, PSRR, and thermal margin across temperature.

Can TLV70015DSET operate with a 0.1-μF output capacitor?

Yes-TLV70015DSET is explicitly designed to be stable with an effective output capacitance of ≥0.1 μF. This refers to the capacitance value under actual operating bias voltage and temperature, not the nominal rated value. X5R/X7R 0.1-μF 0402 ceramics are commonly used and validated.

Does TLV70015DSET have reverse-voltage protection?

No. The TLV70015DSET contains a body diode between OUT and IN that conducts when VOUT > VIN. During reverse-voltage conditions, current is not limited-external protection (e.g., series Schottky diode or MOSFET) is required if reverse bias exceeds 5% of rated output current.

What is the thermal shutdown behavior of TLV70015DSET?

TLV70015DSET triggers thermal shutdown at TJ ≈ 160°C and resets at TJ ≈ 140°C. During sustained overload, it cycles between shutdown and regulation. The WSON-6 package's RθJA = 321.3°C/W means power dissipation above ~370 mW in still air will trigger shutdown-PCB copper area is essential for thermal management.

Is TLV70015DSET compatible with 1.8-V GPIO for enable control?

Yes. TLV70015DSET's EN pin has a guaranteed high threshold of ≥0.9 V and low threshold of ≤0.4 V, making it fully compatible with standard 1.8-V CMOS logic outputs. No level-shifting is needed-direct connection to MCU GPIO suffices.
