Product details
Overview
TLV70533YFFR from Texas Instruments is a 3.3-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, enabling stable power for noise-sensitive RF circuits in space-constrained portable devices.
For engineers reviewing the TLV70533YFFR datasheet, TLV70533YFFR pinout, TLV70533YFFR application, or TLV70533YFFR equivalent, key selection criteria include ultra-low profile packaging, sub-100-mV load transient response, PSRR of 70 dB at 1 kHz, and compatibility with 0.1-μF ceramic output capacitors.
Technical Context
The TLV70533YFFR uses a PMOS pass transistor architecture to achieve low dropout and high PSRR with minimal VIN–VOUT headroom. Its internal bandgap reference and error amplifier deliver ±0.5% DC accuracy across –40°C to +125°C and 0–200 mA load range.
It integrates active enable logic (EN threshold: 0.9 V high, 0.4 V low), thermal shutdown (160°C trip), and overcurrent protection. The device operates stably with ≥0.1 μF effective ceramic output capacitance and supports zero-load regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±0.5% (ensures precise rail generation for 3.3-V I/O and core logic) |
| Max Output Current | 200 mA (supports moderate-power microcontrollers and RF transceivers) |
| Dropout Voltage | 145 mV at 200 mA (enables operation down to VIN = 3.445 V, extending battery life) |
| Quiescent Current | 35 μA (minimizes standby power in always-on sensor nodes) |
| PSRR | 70 dB at 1 kHz (suppresses switching noise from adjacent DC/DC converters) |
| Output Noise | 26.6 μVRMS (100 Hz–100 kHz, VOUT = 1.8 V; confirms suitability for RF analog front-ends) |
| Input Voltage Range | 2 V to 5.5 V (compatible with single-cell Li-ion, Li-poly, and 3.3-V/5-V system rails) |
Pinout & Package
TLV70533YFFR is housed in a 4-pin, 0.77-mm × 0.77-mm, 0.15-mm max height DSBGA (Die Size Ball Grid Array) package - optimized for ultra-thin mobile PCBs and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (A1) | Ground reference | Primary return path for load current and internal bias; requires low-inductance connection to PCB ground plane |
| EN (A2) | Enable control input | Active-high logic interface; asserts regulator when >0.9 V, disables to <0.4 V (draws only 1 μA in shutdown) |
| VIN (B2) | Power input | Accepts 2–5.5 V; requires local 1-μF ceramic decoupling to minimize input ripple and improve transient response |
| VOUT (B1) | Regulated output | Delivers stable 3.3 V; must be bypassed with ≥0.1 μF ceramic capacitor to ensure loop stability and low-noise performance |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small DSBGA footprint | 0.77 mm × 0.77 mm area with 0.15-mm max height - enables placement under narrow-pitch BGAs or in camera module stacks |
| Low-noise regulation | 26.6 μVRMS integrated noise (100 Hz–100 kHz) - meets stringent requirements for RF receivers and precision ADCs |
| High PSRR at low headroom | 70 dB at 1 kHz with only 145-mV VIN–VOUT margin - maintains clean supply even when input rail sags near VOUT |
| Zero-load regulation | Maintains 3.3 V ±0.5% accuracy with no output load - critical for systems with intermittent or burst-mode loads |
| Thermal & current protection | Auto-recovering thermal shutdown (160°C trip) and foldback current limit - prevents damage during short-circuit or overload events |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|

FAQ
What is the maximum input voltage rating for TLV70533YFFR?
The absolute maximum input voltage for TLV70533YFFR is 6 V, but the recommended operating range is 2 V to 5.5 V. Exceeding 5.5 V may trigger internal protection or degrade reliability. Operation within the recommended range ensures full specification compliance across temperature and load conditions for TLV70533YFFR.
Does TLV70533YFFR require an external pull-up resistor on the EN pin?
No, TLV70533YFFR does not require an external pull-up on EN. Its enable threshold is 0.9 V (min) for activation and 0.4 V (max) for shutdown, allowing direct interfacing with standard GPIOs. If enable functionality is unused, EN may be tied directly to VIN - a configuration fully supported in TLV70533YFFR's recommended operating conditions.
Can TLV70533YFFR operate with a 0.1-μF output capacitor?
Yes, TLV70533YFFR is explicitly designed to be stable with an effective output capacitance as low as 0.1 μF (ceramic). This capability is verified across temperature and load, enabling use of small, low-cost, high-bias-capacitance MLCCs - a key design advantage confirmed in the TLV70533YFFR datasheet Section 6.5 and Figure 15.
What is the thermal shutdown behavior of TLV70533YFFR?
TLV70533YFFR activates thermal shutdown at 160°C junction temperature and resets at 140°C. During sustained overload, it cycles between current limit and shutdown - a self-protecting behavior documented in Section 7.3.1. This hysteresis prevents latch-up and ensures safe recovery without external intervention for TLV70533YFFR.
Is TLV70533YFFR pin-compatible with other TLV705 variants?
Yes, all TLV705xYFFR parts (including TLV70533YFFR) share identical 4-pin DSBGA pinout (GND/A1, EN/A2, VIN/B2, VOUT/B1) and package dimensions (0.77 mm × 0.77 mm). Voltage variants differ only in internal feedback network - enabling seamless BOM swaps without layout changes for TLV70533YFFR and related fixed-output versions.
