Texas Instruments TLV70525PYFPR

Overview

TLV70525PYFPR from Texas Instruments is a 2.5-V fixed-output, 200-mA low-dropout (LDO) linear regulator in a 0.77-mm × 0.77-mm DSBGA package. It delivers 0.5% output accuracy, 35-μA quiescent current, 145-mV dropout at 200 mA, and 70-dB PSRR at 1 kHz-designed for powering RF-sensitive subsystems in battery-operated handheld devices.

For engineers reviewing the TLV70525PYFPR datasheet, TLV70525PYFPR pinout, TLV70525PYFPR application, or TLV70525PYFPR equivalent, key selection considerations include ultra-low profile packaging (0.15-mm max height), stability with only 0.1-μF ceramic output capacitance, enable-controlled shutdown with 1-μA quiescent current, and thermal/overcurrent protection for Li-ion–powered portable electronics.

Technical Context

The TLV70525PYFPR uses a PMOS pass transistor architecture to achieve low dropout and high PSRR with minimal VIN–VOUT headroom. Its error amplifier enables 0.5% DC accuracy across –40°C to +125°C and supports zero-load regulation.

It integrates undervoltage lockout (UVLO) at 1.9 V, active-high enable logic (VIH = 0.9 V, VIL = 0.4 V), and internal thermal shutdown (trip at 160°C, reset at 140°C). The device remains stable with ≥0.1 μF effective ceramic output capacitance and requires no external compensation.

FAQ

What is the minimum input voltage required for TLV70525PYFPR to maintain regulation at full 200-mA load?

The TLV70525PYFPR requires VIN ≥ VOUT + VDO = 2.5 V + 0.145 V = 2.645 V to sustain regulation at 200 mA. Below this, it enters dropout mode where VOUT tracks VIN minus dropout voltage. This threshold enables extended runtime from single-cell Li-ion batteries discharging to 2.65 V.

Can TLV70525PYFPR operate stably with a 0.1-μF ceramic output capacitor, and why is this significant?

Yes, TLV70525PYFPR is explicitly designed to remain stable with an effective output capacitance as low as 0.1 μF. This allows use of compact, low-cost X5R/X7R ceramics instead of larger tantalum or polymer capacitors-reducing PCB area, BOM cost, and voltage derating issues in high-bias applications.

How does the enable pin (EN) of TLV70525PYFPR interface with modern low-voltage microcontrollers?

The TLV70525PYFPR EN pin has a low turn-on threshold of 0.9 V (min) and turn-off threshold of 0.4 V (max), making it directly compatible with 1.8-V and 2.5-V GPIO outputs without level shifters. When unused, EN can be tied to VIN for always-on operation.

What protection features are integrated into TLV70525PYFPR, and how do they behave under fault conditions?

TLV70525PYFPR includes thermal shutdown (160°C trip, 140°C reset) and foldback current limiting (260–550 mA). During overload, it enters current limit-holding output current constant while VOUT drops-and cycles between shutdown and restart if thermal limits are repeatedly exceeded.

Is TLV70525PYFPR suitable for powering RF circuitry, and which specifications support this use case?

Yes, TLV70525PYFPR is optimized for RF applications: its 26.6 μVRMS output noise (100 Hz–100 kHz) and 70-dB PSRR at 1 kHz minimize phase noise and spurious emissions in VCOs, PLLs, and RF transceivers-key for maintaining EVM and ACLR compliance in Bluetooth/Wi-Fi/Zigbee systems.
