Product details
Overview
TLV70509YFPT from Texas Instruments is a 0.9-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, and 145-mV dropout at 200 mA - optimized for Li-ion–powered handheld devices requiring ultra-low profile power management.
For engineers reviewing the TLV70509YFPT datasheet, TLV70509YFPT pinout, TLV70509YFPT application, or TLV70509YFPT equivalent, key selection criteria include its sub-1-V output capability, 0.1-μF minimum stable output capacitance, high PSRR (70 dB @ 1 kHz), thermal shutdown protection, and enable-controlled startup with 100-μs rise time.
Technical Context
The TLV70509YFPT uses a PMOS pass transistor architecture enabling ultra-low dropout and reverse-body-diode conduction when VOUT > VIN. Its internal bandgap reference and error amplifier deliver 0.5% typical DC accuracy across –40°C to +125°C and 0–200 mA load range.
It features active-high enable (EN) with 0.9-V turn-on threshold and 0.4-V shutdown threshold, supporting direct GPIO interfacing from modern low-voltage processors. The device operates stably with only 0.1 μF ceramic output capacitance due to internal compensation optimized for minimal bias/temperature derating sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 0.9 V - enables direct powering of sub-1-V logic cores and RF ICs without external feedback. |
| Max Output Current | 200 mA - sufficient for baseband processors, Bluetooth radios, and sensor hubs in compact portable designs. |
| Dropout Voltage | 145 mV @ 200 mA - allows operation down to VIN = 1.045 V, extending battery runtime in single-cell Li-ion systems. |
| Quiescent Current | 35 μA - minimizes standby power loss in always-on subsystems like wake-on-RF or real-time clocks. |
| PSRR | 70 dB @ 1 kHz - suppresses switching noise from adjacent DC/DC converters, critical for RF and audio signal integrity. |
| Stability Capacitance | 0.1 μF ceramic - reduces BOM cost and PCB area vs. traditional 2.2–10 μF tantalum solutions. |
| Enable Threshold | VHI = 0.9 V, VLO = 0.4 V - compatible with 1.2-V and 1.8-V GPIOs without level-shifting circuitry. |
Pinout & Package
TLV70509YFPT is housed in a 4-pin, 0.77-mm × 0.77-mm, 0.15-mm max height DSBGA (YFPT) package - optimized for space-constrained mobile applications where board thickness and component footprint are critical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Primary return path for load current and internal bias; must be connected to low-impedance system ground plane. |
| EN | Enable control input | Active-high digital control: ≥0.9 V enables regulation; ≤0.4 V forces shutdown with 1-μA quiescent draw. |
| VIN | Input supply | Accepts 2 V to 5.5 V; requires local 1-μF ceramic bypass capacitor to GND for transient immunity. |
| VOUT | Regulated output | Delivers stable 0.9 V; requires ≥0.1 μF ceramic capacitor to GND - no ESR requirements. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile packaging | 0.15-mm max height DSBGA enables integration into <0.6-mm-thin smartphone modules and wearables. |
| Sub-1-V fixed output | 0.9-V nominal output supports next-generation ultra-low-voltage SoCs and RF transceivers requiring precise sub-1-V rails. |
| Thermal & overcurrent protection | Integrated shutdown triggers at 160°C junction temp and limits output current to ~400 mA, preventing damage during fault conditions. |
| Low-noise regulation | 26.6 μVRMS (100 Hz–100 kHz) enables clean power for sensitive analog circuits including ADCs and PLLs. |
| Fast start-up time | 100 μs to 98% of 0.9 V with 1-μF COUT - ensures rapid system wake-up without software delay penalties. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL7407LPWPR | 7-channel high-side driver with integrated 0.9-V LDO; higher IQ (100 μA), larger HTSSOP-16 package. | Designed for LED/display driver integration, not standalone low-noise power regulation. | Select only if multi-channel driving + regulation is required; not a drop-in replacement for TLV70509YFPT's single-rail function. |
| TPS7A0509PDBVR | 0.9-V fixed LDO in SOT-23-5; 25-μA IQ, 170-mV dropout @ 200 mA, requires ≥1-μF COUT. | Larger footprint and height; less suitable for ultra-thin mobile PCBs but offers wider VIN range (1.4–5.5 V). | Choose when board space allows SOT-23 and lower IQ is prioritized over ultra-small form factor. |
Compared with TPL7407LPWPR and TPS7A0509PDBVR, TLV70509YFPT uniquely combines 0.77-mm × 0.77-mm DSBGA packaging, 0.1-μF stability, and 35-μA IQ - making it the only option meeting strict height and capacitor-size constraints in next-gen wearable and smartphone designs.

FAQ
What is the minimum output capacitance required for stable operation of TLV70509YFPT?
The TLV70509YFPT is stable with an effective output capacitance as low as 0.1 μF ceramic. This value is verified across temperature and load conditions per TI SBVS151F datasheet Section 6.5. Using smaller capacitors reduces PCB area and cost while maintaining phase margin >45°, eliminating the need for ESR-tuned solutions.
Does TLV70509YFPT support shutdown mode, and what is its quiescent current in that state?
Yes, TLV70509YFPT supports active-low shutdown via the EN pin: pulling EN ≤0.4 V disables regulation and reduces ground current to 1 μA (typical). This ultra-low shutdown IQ preserves battery charge in always-connected IoT endpoints and enables fast wake-up without external discharge circuitry.
Can TLV70509YFPT operate with an input voltage below 2 V?
No - TLV70509YFPT has a specified minimum input voltage of 2 V per Recommended Operating Conditions (Section 6.3). Attempting operation below 2 V may trigger undervoltage lockout (UVLO), causing unregulated output or intermittent dropout. For sub-2-V inputs, consider TI's TPS7A05 series with 1.4-V minimum VIN.
What is the thermal shutdown threshold for TLV70509YFPT, and does it auto-recover?
TLV70509YFPT activates thermal shutdown at 160°C junction temperature and resets at 140°C. This hysteresis prevents oscillation near trip point. Auto-recovery occurs once die temperature falls below 140°C, restoring regulation without external intervention - critical for transient overload resilience in handheld thermal envelopes.
Is TLV70509YFPT pin-compatible with other members of the TLV705 family?
Yes - all TLV705xYFPT variants (e.g., TLV70512YFPT, TLV70515YFPT) share identical 4-pin DSBGA (YFPT) pinout: GND (A1), EN (A2), VOUT (B1), VIN (B2). This allows voltage-scaling flexibility within the same PCB footprint, simplifying design reuse across product variants requiring different output rails.
