Texas Instruments TLV702475DBVT

Overview

TLV702475DBVT from Texas Instruments is a 4.75-V fixed-output, 300-mA low-dropout (LDO) linear regulator in SOT-23-5 package, featuring 2% output accuracy, 35 μA quiescent current, 260 mV dropout at 300 mA, and 68 dB PSRR at 1 kHz - designed for Li-ion–powered handheld devices requiring stable, low-noise supply under light-to-moderate load.

For engineers reviewing the TLV702475DBVT datasheet, TLV702475DBVT pinout, TLV702475DBVT application, or TLV702475DBVT equivalent, key selection criteria include dropout voltage at full load, shutdown current (<1 μA), thermal shutdown threshold (165°C), stability with 0.1-μF ceramic output capacitance, and EN pin logic thresholds (0.9 V high / 0.4 V low).

Technical Context

The TLV702475DBVT uses a PMOS pass transistor to achieve low dropout and maintain regulation down to VIN = VOUT + 260 mV at 300 mA. Its precision bandgap reference and error amplifier deliver ±2% DC accuracy across –40°C to +125°C junction temperature.

It integrates active protection: thermal shutdown (trip at 165°C, reset at 145°C), current limit (320–860 mA), undervoltage lockout (UVLO at 1.9 V), and enable-controlled shutdown with 400 nA typical ground current. The device is stable with ≥0.1 μF effective output capacitance and requires no minimum load.

FAQ

What is the maximum input voltage rating for TLV702475DBVT?

The absolute maximum input voltage for TLV702475DBVT is 6.0 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent damage. For reliable continuous operation, the recommended input range is 2.0 V to 5.5 V per the Recommended Operating Conditions - ensuring compatibility with single-cell Li-ion batteries and standard 3.3-V/5-V supply rails.

Does TLV702475DBVT require an external pull-up resistor on the EN pin?

No, TLV702475DBVT does not require an external pull-up resistor on the EN pin. The device operates normally when EN is connected directly to IN (for always-on operation) or driven by a logic signal. Its EN pin draws only 0.04 μA, so standard GPIO outputs can drive it directly without loading concerns. Internal logic thresholds (0.9 V high / 0.4 V low) ensure compatibility with 1.8-V and 3.3-V logic families.

Can TLV702475DBVT operate without any load connected to the OUT pin?

Yes, TLV702475DBVT regulates to full accuracy with no output load - a key feature confirmed in the Electrical Characteristics table (VOUT tested at IOUT = 0 mA). This zero-load capability simplifies designs for systems with variable or intermittent loads, eliminates need for dummy loads, and avoids inefficiency penalties in standby states.

What is the thermal resistance (RθJA) of TLV702475DBVT in its SOT-23-5 package?

The junction-to-ambient thermal resistance (RθJA) for TLV702475DBVT in the DBV (SOT-23-5) package is 249.2°C/W, as measured on a standard 2-layer JEDEC test board. This value assumes proper PCB layout with adequate copper pour on the GND pad. Real-world RθJA will improve with enhanced thermal vias and larger ground planes - critical for sustaining 300 mA output in ambient temperatures up to +85°C.

Is TLV702475DBVT compatible with 0.1-μF X5R ceramic output capacitors?

Yes, TLV702475DBVT is explicitly characterized and guaranteed stable with ≥0.1 μF effective output capacitance, including X5R and X7R dielectrics. The datasheet confirms stability under bias and temperature derating - meaning a 0.1-μF X5R capacitor rated at 6.3 V or higher remains ≥0.1 μF at 4.75 V and operating temperature, satisfying the stability requirement without needing larger or more expensive alternatives.
