Texas Instruments TLV70528YFPR

Overview

TLV70528YFPR 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. 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 power-sensitive RF subsystems in compact battery-powered devices.

For engineers reviewing the TLV70528YFPR datasheet, TLV70528YFPR pinout, TLV70528YFPR application, or TLV70528YFPR 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 in disable mode, and thermal/overcurrent protection for robust operation in handheld electronics.

Technical Context

The TLV70528YFPR uses a PMOS pass transistor to achieve low dropout and maintain regulation down to (VIN – VOUT) = 145 mV at full load. Its error amplifier enables 0.5% DC accuracy across –40°C to +125°C and supports zero-load regulation.

It integrates undervoltage lockout (UVLO) triggering at 1.9 V, active-high enable logic (VIH = 0.9 V, VIL = 0.4 V), and thermal shutdown at 160°C with hysteresis (140°C reset). The device is stable with ≥0.1 μF effective output capacitance and achieves 26.6 μVRMS integrated noise (100 Hz–100 kHz) at 1.8 V output.

FAQ

What is the minimum input voltage required for TLV70528YFPR to regulate 2.8 V output?

The TLV70528YFPR requires VIN ≥ VOUT + VDO. With a typical dropout of 145 mV at 200 mA, the minimum input is 2.945 V under full load. At lighter loads, dropout decreases-for example, 105 mV at 150 mA yields a 2.905 V minimum. Input must also exceed the 1.9 V UVLO threshold to initiate regulation.

Can TLV70528YFPR operate with less than 0.1 μF output capacitance?

No-TI specifies stability with ≥0.1 μF effective ceramic output capacitance. Using smaller values risks oscillation or poor transient response. The 0.1 μF minimum accounts for capacitance derating due to DC bias and temperature; actual placed value should be ≥1 μF X5R/X7R ceramic to ensure sufficient effective capacitance across operating conditions.

Does TLV70528YFPR include reverse-voltage protection?

The TLV70528YFPR does not integrate reverse-voltage protection. Its PMOS pass transistor includes a body diode that conducts if VOUT exceeds VIN, potentially damaging upstream sources. TI recommends external limiting-such as a series Schottky diode or dedicated reverse-protection IC-if reverse-bias conditions are possible in the system.

How does the enable pin (EN) behave during power-up of TLV70528YFPR?

The TLV70528YFPR EN pin is active-high with VIH = 0.9 V (min) and VIL = 0.4 V (max). During power-up, the regulator remains off until EN rises above 0.9 V. If EN is tied to VIN, startup occurs automatically once VIN exceeds 1.9 V (UVLO) and reaches the enable threshold-ensuring controlled sequencing without external logic.

Is TLV70528YFPR compatible with 1.8 V GPIOs for enable control?

Yes-TLV70528YFPR's EN pin requires only 0.9 V to activate, making it directly compatible with 1.8 V GPIO outputs. This eliminates level shifters in modern low-voltage microcontrollers and SoCs. The EN pin draws just 0.01 μA, imposing negligible loading on the driving GPIO.
