Product details
Overview
TLV70733APDQNR from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise LDO regulator with 3.3 V fixed output, 0.5% DC accuracy, 70 dB PSRR at 100 Hz, and stable operation with only 0.1 µF output capacitance. It serves as a power supply for noise-sensitive RF and portable subsystems in space-constrained applications.
For engineers reviewing the TLV70733APDQNR datasheet, TLV70733APDQNR pinout, TLV70733APDQNR application, or TLV70733APDQNR equivalent, key selection criteria include dropout voltage (220 mV at 150 mA), thermal shutdown/overcurrent protection, enable-pin logic thresholds (VIH = 0.9 V, VIL = 0.4 V), and compatibility with low-bias ceramic capacitors in 1-mm × 1-mm X2SON packaging.
Technical Context
The TLV70733APDQNR implements a PMOS pass transistor architecture enabling ultra-low dropout and fast load transient response. Its internal bandgap reference and error amplifier deliver 0.5% output accuracy across –40°C to +125°C junction temperature and 0–200 mA load range.
It features active-high enable with hysteresis-free thresholding (0.4 V disable / 0.9 V enable), integrated thermal shutdown, and overcurrent limiting (240–450 mA). The TLV707P variant adds an internal 120-Ω pulldown resistor - but TLV70733APDQNR is a TLV707 (not TLV707P) variant, so it lacks active pulldown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 3.3 V ±0.5% - ensures stable bias for 3.3-V logic, RF front-ends, and sensors without external feedback. |
| Max output current | 200 mA - supports moderate-power microcontrollers, transceivers, and analog signal chains. |
| Quiescent current | 25 µA - enables multi-year battery life in always-on wearable and IoT edge nodes. |
| PSRR | 70 dB at 100 Hz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Dropout voltage | 220 mV at 150 mA - allows operation from 3.53 V input when regulating 3.3 V, maximizing battery utilization. |
| Stability capacitance | 0.1 µF min - permits use of small, low-cost X5R/X7R ceramics, reducing BOM count and PCB area. |
| Enable threshold | VIH = 0.9 V, VIL = 0.4 V - compatible with low-voltage GPIOs (e.g., 1.8-V I/O domains) without level-shifting. |
Pinout & Package
TLV70733APDQNR uses the DQN (X2SON) 4-pin package: 1.00 mm × 1.00 mm body with exposed thermal pad. Pin 1 = OUT, Pin 2 = GND, Pin 3 = EN, Pin 4 = IN.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Regulated output | Delivers stable 3.3 V to load; requires ≥0.1 µF ceramic capacitor to GND for stability. |
| GND (Pin 2) | Ground reference | Common return path for input/output currents and internal circuitry; connects to thermal pad for heat dissipation. |
| EN (Pin 3) | Enable control | Active-high logic input; device enabled above 0.9 V, disabled below 0.4 V; draws ≤0.01 µA when high. |
| IN (Pin 4) | Input supply | Accepts 2.0–5.5 V input; requires local 1-µF ceramic bypass capacitor to GND for transient immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise regulation | 45 µVRMS output noise (100 Hz–100 kHz) - preserves SNR in ADCs, audio codecs, and RF receivers. |
| Ultra-small footprint | 1-mm × 1-mm X2SON package - fits within tight layouts of smartphones, hearables, and medical patches. |
| Wide input range | 2.0 V to 5.5 V input - accommodates single-cell Li-ion (2.7–4.2 V), USB (4.5–5.5 V), and dual-cell alkaline inputs. |
| Zero-load regulation | Maintains 0.5% accuracy with no output load - critical for standby modes where downstream circuits are powered off. |
| Robust protection | Thermal shutdown + foldback current limit - prevents damage during short-circuit or overheating events without external components. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLS850F33TJ | Automotive-grade AEC-Q100 qualified; higher IQ (45 µA); wider temp range (–40°C to +150°C); integrated watchdog. | Designed for automotive infotainment and ADAS modules requiring functional safety support. | Select TLS850F33TJ only if AEC-Q100 qualification, extended temperature, or watchdog functionality is required. |
| TPS7A0533PDQNR | Lower IQ (250 nA typical); same 3.3 V output; smaller 0.8-mm × 0.8-mm X2SON; no EN pin - always-on. | Optimized for ultra-low-power IoT endpoints where enable control is unnecessary and nanoamp IQ is critical. | Choose TPS7A0533PDQNR when system-level enable sequencing is handled externally and sub-µA shutdown is mandatory. |
Compared with TLS850F33TJ and TPS7A0533PDQNR, TLV70733APDQNR balances low IQ (25 µA), fast transient response, and flexible enable control in a cost-effective industrial-grade package - making it ideal for portable consumer electronics where size, noise, and GPIO compatibility are prioritized over automotive qualification or nanoamp standby.

FAQ
What is the maximum input voltage rating for TLV70733APDQNR?
The absolute maximum input voltage for TLV70733APDQNR is 6.0 V. However, the recommended operating range is 2.0 V to 5.5 V. Exceeding 6.0 V risks permanent damage per the Absolute Maximum Ratings table. For reliable operation in battery-powered systems, keep VIN ≤ 5.5 V - e.g., within USB 2.0 specification or fully charged single-cell Li-ion (≤4.35 V).
Does TLV70733APDQNR include an active pulldown circuit on the output?
No, TLV70733APDQNR does not include an active pulldown circuit. It belongs to the TLV707 (not TLV707P) family variant. Only TLV707P devices integrate a 120-Ω internal pulldown resistor activated during shutdown. TLV70733APDQNR relies on external discharge paths if rapid output voltage decay is required.
Can TLV70733APDQNR operate with zero load current while maintaining regulation?
Yes, TLV70733APDQNR regulates to its specified 3.3 V ±0.5% accuracy even with no output load. This zero-load capability is explicitly confirmed in the datasheet and enables reliable operation in systems where downstream circuits may be fully powered down while the LDO remains active.
What is the minimum output capacitor required for stability with TLV70733APDQNR?
The minimum effective output capacitance required for stability is 0.1 µF. This value refers to the capacitance under actual operating bias voltage and temperature - not the nominal rated value. A 0.1-µF X5R or X7R ceramic capacitor (e.g., 0201 or 0402) is sufficient and commonly used to meet this requirement in compact designs.
Is TLV70733APDQNR pin-compatible with other variants in the TLV707 family?
Yes, all TLV707 and TLV707P devices in the DQN (X2SON) 4-pin package share identical pinout: Pin 1 = OUT, Pin 2 = GND, Pin 3 = EN, Pin 4 = IN. TLV70733APDQNR is therefore pin-compatible with TLV70712APDQNR, TLV70728APDQNR, and TLV707P variants - though functional differences (e.g., pulldown) must be verified per application.
