Texas Instruments TLV70512YFPR

Overview

TLV70512YFPR from Texas Instruments is a 1.2-V fixed-output, 200-mA low-dropout (LDO) linear regulator in a 0.77-mm × 0.77-mm DSBGA package. It delivers 0.5% typical output accuracy, 35-μA quiescent current, 145-mV dropout at 200 mA, and 70-dB PSRR at 1 kHz - optimized for Li-ion–powered handheld devices requiring stable, low-noise bias.

For engineers reviewing the TLV70512YFPR datasheet, TLV70512YFPR pinout, TLV70512YFPR application, or TLV70512YFPR equivalent, key selection criteria include ultra-small footprint compatibility, sub-1-μF ceramic capacitor stability, enable-controlled power sequencing, thermal shutdown behavior, and performance under low VIN–VOUT headroom conditions.

Technical Context

The TLV70512YFPR uses a PMOS pass transistor to achieve low dropout and maintain regulation down to 2 V input with 1.2 V output. Its error amplifier provides 0.5% DC accuracy across –40°C to +125°C and supports zero-load regulation.

It features active-high enable (EN), undervoltage lockout (UVLO) at 1.9 V, thermal shutdown at 160°C, and internal current limiting (260–550 mA). The device stabilizes 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 TLV70512YFPR to regulate 1.2 V at 200 mA?

The TLV70512YFPR requires a minimum input voltage of 1.345 V to maintain regulation at 200 mA load, based on its 145-mV dropout specification. Below this, the output voltage drops linearly with input. Operation is guaranteed from 2 V to 5.5 V per recommended conditions, ensuring compatibility with single-cell Li-ion batteries across full discharge range.

Does TLV70512YFPR require an external pull-up resistor on the EN pin?

No, TLV70512YFPR does not require an external pull-up on EN. The EN pin has internal biasing and is designed for direct connection to a GPIO or VIN. When tied to VIN (2–5.5 V), the device remains enabled; when driven below 0.4 V, it enters shutdown with ground current reduced to 1 μA nominal.

Can TLV70512YFPR operate stably with a 0.1-μF ceramic output capacitor?

Yes, TLV70512YFPR is explicitly characterized and guaranteed stable with an effective output capacitance of 0.1 μF - including derating effects from DC bias and temperature. This enables use of small, low-cost X5R/X7R ceramics and eliminates need for larger, higher-profile capacitors.

What is the thermal shutdown behavior of TLV70512YFPR under sustained overload?

TLV70512YFPR triggers thermal shutdown at 160°C junction temperature and automatically recovers when junction cools to ~140°C. During repeated fault cycling, it alternates between current-limited conduction and shutdown - protecting against permanent damage while maintaining safe operating limits per JEDEC JESD22-A104.

How does the output noise of TLV70512YFPR compare to other 1.2-V LDOs in DSBGA packages?

TLV70512YFPR delivers 26.6 μVRMS integrated noise (100 Hz–100 kHz) at 1.2-V output - among the lowest in its class. Competing DSBGA LDOs such as TPS7A0512PDBVR specify 45 μVRMS, making TLV70512YFPR preferred for RF-bias and precision analog applications where noise directly impacts system SNR.
