Texas Instruments TLV70130DBVT

Overview

TLV70130DBVT from Texas Instruments is a 3.0-V fixed-output, 150-mA low-dropout linear regulator with 3.4-μA typical quiescent current, 2.5–24-V input range, and SOT-23-5 (DBV) package. It delivers stable voltage to ultra-low-power microcontrollers in battery-powered systems such as smart sensors and portable medical devices.

For engineers reviewing the TLV70130DBVT datasheet, TLV70130DBVT pinout, TLV70130DBVT application, or TLV70130DBVT equivalent, key selection criteria include dropout voltage at 100 mA (850 mV typ), output capacitor stability down to 0.47 μF, internal soft-start, overcurrent protection, and operation across –40°C to +125°C junction temperature.

Technical Context

The TLV70130DBVT uses a PMOS pass transistor architecture enabling low dropout and reverse-current sensitivity. Its leakage-null control circuit activates only under high-VIN (>18 V), high-temperature (>100°C), and ultra-light-load (<5 μA) conditions to maintain IQ stability.

It operates in two distinct functional modes: normal regulation (VIN > VOUT + VDO) and dropout mode (VIN < VOUT + VDO), where output voltage tracks input and transient response degrades significantly. The brick-wall current limit (160–500 mA, depending on chip revision) engages during short-circuit faults without foldback.

Key Specifications

Pinout & Package

TLV70130DBVT is housed in a 2.90 mm × 1.60 mm 5-pin SOT-23 (DBV) package with exposed thermal pad not connected internally. Pins 4 and 5 are no-connect (NC) terminals and may be left floating or tied to GND for improved thermal performance.

FAQ

What is the maximum input voltage rating for TLV70130DBVT?

The TLV70130DBVT has an absolute maximum input voltage of 30 V for the new-chip revision, but its recommended operating range is 2.5 V to 24 V. Exceeding 24 V continuously risks exceeding thermal limits or triggering overvoltage stress, even though 30 V is tolerated briefly per absolute ratings. Always verify actual board-level input transients and derate accordingly in safety-critical designs.

Does TLV70130DBVT require an input capacitor?

TLV70130DBVT does not require an input capacitor for stability, but Texas Instruments recommends a 0.1-μF ceramic capacitor from IN to GND to suppress high-frequency noise, improve PSRR, and mitigate ringing caused by source impedance >0.5 Ω. This is especially critical in systems with long input traces or switching regulators upstream.

Can TLV70130DBVT be used with a 0.47-μF output capacitor?

Yes - TLV70130DBVT is explicitly characterized and guaranteed stable with output capacitance ≥0.47 μF (ceramic, X7R/X5R/C0G). The datasheet accounts for 50% effective capacitance derating, so a nominal 1.0-μF capacitor ensures ≥0.5 μF minimum effective value across voltage and temperature. Using exactly 0.47 μF is acceptable if derating margin is verified.

What is the dropout voltage of TLV70130DBVT at 150 mA?

At 150 mA load, the dropout voltage of TLV70130DBVT is typically 1.8 V (based on Figure 6-10 curve extrapolation and RDS(ON) calculation), though the datasheet specifies 850 mV at 100 mA. This increase reflects ohmic behavior of the PMOS pass device; designers must ensure sufficient VIN headroom - e.g., ≥4.8 V input for reliable 3.0-V output at full load.

Is TLV70130DBVT pin-compatible with other TLV701 variants?

Yes - all TLV701xxDBVT variants (e.g., TLV70133DBVT) share identical 5-pin SOT-23 (DBV) pinout: Pin 1 = OUT, Pin 2 = GND, Pin 3 = IN, Pins 4–5 = NC. Output voltage is set internally, so swapping fixed-output versions requires only firmware or load verification - no PCB change is needed.
