Texas Instruments TLV705075YFPR

Overview

TLV705075YFPR from Texas Instruments is a 0.75-V fixed-output, 200-mA low-dropout (LDO) linear regulator in a 0.77-mm × 0.77-mm DSBGA package, featuring 0.5% typical output accuracy, 35-μA quiescent current, and 145-mV dropout at 200 mA - designed for powering ultra-low-voltage cores in battery-operated handheld devices.

For engineers reviewing the TLV705075YFPR datasheet, TLV705075YFPR pinout, TLV705075YFPR application, or TLV705075YFPR equivalent, key selection criteria include its sub-1-V output capability, stability with only 0.1-μF ceramic output capacitance, high PSRR (70 dB @ 1 kHz), thermal shutdown protection, and enable-controlled sequencing in space-constrained RF subsystems.

Technical Context

The TLV705075YFPR employs a PMOS pass transistor architecture enabling ultra-low dropout and eliminating reverse-current flow under VOUT > VIN conditions. Its bandgap reference and error amplifier deliver 0.5% DC accuracy across –40°C to +125°C and 0–200 mA load range.

It integrates active enable logic (EN threshold: 0.9 V high, 0.4 V low), undervoltage lockout (UVLO at 1.9 V), and internal current limiting (typ. 400 mA). Unlike the TLV705P variant, it lacks active pulldown - output discharge relies on load path only.

FAQ

What is the minimum input voltage required for TLV705075YFPR to regulate 0.75 V at 200 mA?

The TLV705075YFPR requires VIN ≥ VOUT + VDO = 0.75 V + 0.145 V = 0.895 V to maintain regulation at 200 mA. However, per recommended operating conditions, VIN must be ≥2 V for full specification compliance - ensuring proper UVLO release, internal bias stability, and PSRR performance across temperature.

Does TLV705075YFPR support reverse current protection when VOUT exceeds VIN?

Yes. TLV705075YFPR uses a PMOS pass transistor with an inherent body diode oriented to block reverse current flow from VOUT to VIN. This prevents backfeeding into upstream supplies - critical in multi-rail systems where 0.75-V domain may remain powered while main battery disconnects.

Can TLV705075YFPR operate stably with a 0.047-μF ceramic output capacitor?

No. The TLV705075YFPR is specified stable with ≥0.1 μF effective ceramic output capacitance. Using 0.047 μF violates the minimum stability requirement and risks oscillation or poor transient response - TI's design guidelines mandate ≥0.1 μF placed directly at the VOUT pin.

Is TLV705075YFPR pin-compatible with other TLV705 variants like TLV70512YFPR?

Yes. All TLV705 YFPR-packaged variants - including TLV705075YFPR, TLV70512YFPR, and TLV70518YFPR - share identical 4-pin DSBGA (YFPR) pinout (GND/A1, EN/A2, VIN/B2, VOUT/B1) and footprint. Only the output voltage differs; no PCB redesign is needed when scaling supply rails.

What is the thermal shutdown behavior of TLV705075YFPR under sustained overload?

When junction temperature reaches 160°C, TLV705075YFPR enters thermal shutdown, disabling the pass element and reducing ground current to ~1 μA. It automatically recovers once TJ falls below 140°C. During repeated fault cycling, this hysteresis protects against latch-up while allowing safe cooldown between events.
