Texas Instruments TLV70528PYFPT

Overview

TLV70528PYFPT 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, 70 dB PSRR at 1 kHz, and stable operation with only 0.1 μF ceramic output capacitance. It powers RF-sensitive subsystems in space-constrained portable electronics.

For engineers reviewing the TLV70528PYFPT datasheet, TLV70528PYFPT pinout, TLV70528PYFPT application, or TLV70528PYFPT equivalent, key selection criteria include ultra-low profile packaging, sub-100 μA shutdown current, thermal/overcurrent protection, compatibility with Li-ion input rails (2 V–5.5 V), and suitability for noise-sensitive analog/RF supply domains.

Technical Context

The TLV70528PYFPT uses a PMOS pass transistor architecture enabling low dropout voltage that scales with load current-145 mV at 200 mA-and maintains regulation down to 2 V input. Its error amplifier achieves ±0.5% DC accuracy across –40°C to +125°C and supports zero-load regulation.

It integrates undervoltage lockout (1.9 V rising threshold), active-high enable logic (0.9 V turn-on, 0.4 V turn-off), and thermal shutdown (160°C trip). Unlike the TLV705P variant, this part lacks active pulldown; output discharge relies on load path only.

FAQ

What is the maximum input voltage rating for TLV70528PYFPT?

The absolute maximum input voltage for TLV70528PYFPT is 6 V, but the recommended operating range is 2 V to 5.5 V. Exceeding 5.5 V may trigger internal protection or cause reliability degradation. Operation within the 2–5.5 V window ensures full specification compliance-including 0.5% output accuracy and 145 mV dropout at 200 mA-as validated in TI's SBVS151F datasheet.

Does TLV70528PYFPT include an enable pin, and what are its voltage thresholds?

Yes, TLV70528PYFPT features an active-high EN pin with a 0.9 V minimum turn-on threshold and 0.4 V maximum turn-off threshold. This allows direct interfacing with low-voltage GPIOs (e.g., 1.8 V or 2.8 V microcontrollers) without level-shifting. The EN pin draws only 0.01 μA, making it ideal for low-power wake-up control in battery-operated systems using TLV70528PYFPT.

Can TLV70528PYFPT operate stably with less than 1 μF output capacitance?

Yes-TLV70528PYFPT is stable with as little as 0.1 μF effective ceramic output capacitance, per TI's electrical specifications. This enables use of small 0402 or 0201 MLCCs, reducing board area and cost. However, a 1 μF capacitor is recommended for optimal transient response and PSRR performance, especially in RF applications where TLV70528PYFPT is commonly deployed.

What protection features does TLV70528PYFPT integrate?

TLV70528PYFPT integrates thermal shutdown (160°C trip, 140°C reset), output current limiting (260–550 mA typical), and undervoltage lockout (1.9 V rising threshold). These functions operate autonomously without external components. Notably, TLV70528PYFPT does not include active pulldown-unlike the TLV705P variant-so output discharge relies solely on the load path when disabled.

Is TLV70528PYFPT pin-compatible with other members of the TLV705 family?

Yes-TLV70528PYFPT shares identical 4-pin DSBGA (YFP) pinout and footprint with all TLV705x and TLV705Px variants in the same package. Pin assignments (GND, EN, VIN, VOUT) and pad layout are standardized across fixed-output voltages from 0.7 V to 4.8 V, enabling drop-in replacement during design iteration or voltage optimization-provided thermal and electrical constraints remain satisfied for TLV70528PYFPT.
