Texas Instruments TLV70528PYFPR

Overview

TLV70528PYFPR from Texas Instruments is a 2.8 V fixed-output, 200-mA low-dropout (LDO) linear regulator in a 0.77-mm × 0.77-mm DSBGA package, featuring 0.5% output accuracy, 35 μA quiescent current, and 145 mV dropout at 200 mA - designed for power-sensitive RF and portable applications including Bluetooth® and Zigbee® devices.

For engineers reviewing the TLV70528PYFPR datasheet, TLV70528PYFPR pinout, TLV70528PYFPR application, or TLV70528PYFPR equivalent, key selection criteria include ultra-low profile packaging, stability with 0.1 μF ceramic output capacitance, high PSRR (70 dB at 1 kHz), thermal shutdown protection, and active-high enable with 0.9 V turn-on threshold.

Technical Context

The TLV70528PYFPR uses a PMOS pass transistor to achieve low dropout and maintain regulation down to (VIN – VOUT) = 145 mV at full load. Its error amplifier delivers 0.5% typical DC accuracy across –40°C to +125°C and supports zero-load regulation.

It integrates undervoltage lockout (UVLO) triggering at 1.9 V, thermal shutdown at 160°C, and internal current limiting (260–550 mA). The device operates with input voltage from 2 V to 5.5 V and remains stable with ≥0.1 μF effective ceramic output capacitance - enabling use of bias-derated, cost-effective MLCCs.

FAQ

What is the minimum input voltage required for TLV70528PYFPR to regulate 2.8 V at 200 mA?

The TLV70528PYFPR requires a minimum input voltage of 2.945 V to maintain regulation at 200 mA load, based on its specified 145 mV dropout voltage (V_DO = 145 mV at I_OUT = 200 mA). Below this, the device enters dropout mode and V_OUT tracks V_IN – 145 mV. This headroom enables efficient operation near end-of-life for single-cell Li-ion batteries.

Can TLV70528PYFPR operate stably with a 0.1 μF output capacitor?

Yes, TLV70528PYFPR is explicitly characterized and guaranteed stable with an effective output capacitance of 0.1 μF ceramic - a key differentiator enabling use of small, bias-derated MLCCs. TI recommends X5R/X7R dielectrics; the device's internal compensation eliminates need for ESR tuning, simplifying layout and reducing BOM cost versus traditional LDOs requiring ≥1 μF.

Does TLV70528PYFPR include reverse-voltage protection?

No, TLV70528PYFPR does not integrate reverse-voltage protection. Its PMOS pass transistor includes a body diode that conducts uncontrolled current if V_OUT exceeds V_IN. For applications with potential reverse bias (e.g., hot-swap, backup power), TI recommends adding an external Schottky diode in series with VIN or a dedicated reverse-protection MOSFET - as detailed in Section 7.3.1 of the TLV705 datasheet.

What is the enable pin behavior during power-up for TLV70528PYFPR?

The TLV70528PYFPR EN pin is active-high with V_HI = 0.9 V (min) and V_LO = 0.4 V (max). When EN rises above 0.9 V, the device starts up with a typical 100 μs delay to 98% of 2.8 V. If EN is tied to VIN, the regulator powers on immediately with input - but note that UVLO (1.9 V) still applies, so regulation only begins once VIN exceeds 1.9 V.

How does TLV70528PYFPR handle thermal overload conditions?

TLV70528PYFPR features thermal shutdown with a 160°C trip point and 140°C hysteresis. During sustained overload, it cycles between current-limit operation and thermal shutdown - dissipating power until junction temperature drops below 140°C, then automatically resuming regulation. This auto-recovery protects the device without requiring external intervention or system-level fault handling.
