Product details
Overview
TLV70730DQNR from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise LDO regulator with 3.0 V fixed output voltage in a 1-mm × 1-mm DQN (X2SON-4) package. It delivers 0.5% DC accuracy, 70 dB PSRR at 100 Hz, and stable operation with only 0.1 µF output capacitance - enabling compact, cost-effective power delivery for battery-powered RF subsystems.
For engineers reviewing the TLV70730DQNR datasheet, TLV70730DQNR pinout, TLV70730DQNR application, or TLV70730DQNR equivalent, key selection criteria include dropout voltage at 150 mA (220–270 mV), shutdown current (1 µA), thermal shutdown/overcurrent protection, and compatibility with low-voltage GPIO enable signals (VIH = 0.9 V).
Technical Context
The TLV70730DQNR implements a PMOS pass transistor architecture with internal bandgap reference, enabling ultra-low IQ and fast load transient response. Its enable threshold (VIH = 0.9 V, VIL = 0.4 V) supports direct interfacing with modern low-voltage microcontroller GPIOs without level-shifting.
It features integrated thermal shutdown and current limiting (240–450 mA), operates across –40°C to +125°C junction temperature, and maintains regulation with zero load - critical for always-on sensor and standby-power circuits in portable electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 3.0 V ±0.5% - ensures stable core/sensor rail without external feedback components. |
| Max output current | 200 mA - sufficient for RF transceivers, MCU cores, and mixed-signal peripherals in handheld devices. |
| Quiescent current | 25 µA - extends battery life in sleep/standby modes of wearables and IoT edge nodes. |
| PSRR | 70 dB at 100 Hz, 50 dB at 1 MHz - suppresses switching noise from DC/DC converters feeding the LDO input. |
| Dropout voltage | 220–270 mV at 150 mA - allows operation from single-cell Li-ion (3.0 V min) or 3.3 V rails with margin. |
| Stability capacitance | 0.1 µF minimum - enables use of small, low-cost X5R/X7R ceramics, reducing PCB area and BOM cost. |
| Shutdown current | 1 µA - minimizes leakage during system-level power gating. |
Pinout & Package
TLV70730DQNR uses the DQN (X2SON-4) package: 1.00 mm × 1.00 mm, 4-pin, bottom-exposed thermal pad. Pin 1 (OUT) and Pin 2 (GND) are adjacent on one side; Pin 3 (EN) and Pin 4 (IN) occupy the opposite side. The thermal pad must be soldered to PCB ground for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Regulated output | Delivers stable 3.0 V; requires ≥0.1 µF ceramic capacitor to GND for stability and transient response. |
| GND (Pin 2) | Ground reference | Common return path for IN, OUT, and EN; 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 - compatible with 1.8 V GPIOs. |
| IN (Pin 4) | Input supply | Accepts 2.0–5.5 V input; requires local 1-µF ceramic decoupling to GND near the pin. |
Key Features
| Feature | Design Value |
|---|---|
| 0.5% output accuracy | Ensures precise voltage delivery to noise-sensitive analog/RF blocks without calibration overhead. |
| 25 µA quiescent current | Reduces no-load power loss to <75 nW at 3 V, critical for multi-year battery operation. |
| 70 dB PSRR @ 100 Hz | Attenuates low-frequency ripple from buck converter outputs, preserving ADC/SERDES signal integrity. |
| 0.1 µF stability | Permits use of 0402/0201 capacitors, cutting solution size by >50% vs legacy LDOs requiring ≥1 µF. |
| Thermal + current protection | Prevents damage during short-circuit or overtemperature events; auto-recovery after cooldown. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC70730DQNR | Same pinout, identical electrical specs, but TI's newer production variant with enhanced ESD rating (±4 kV HBM). | No functional change; suitable for new designs requiring latest qualification. | Select TLC70730DQNR for new designs where long-term supply continuity and updated ESD robustness are prioritized. |
| MCP1700T-3002E/MB | 250 mA max, 1.6 µA IQ, SOT-23-5 package - lower IQ but larger footprint and no enable pin. | Lacks EN control and thermal shutdown; limited to simple always-on rails. | Choose MCP1700T-3002E/MB only when ultra-low IQ dominates and enable/shutdown functionality is unnecessary. |
Compared with TLC70730DQNR, TLV70730DQNR offers identical performance with legacy qualification; versus MCP1700T-3002E/MB, it trades 1.6 µA IQ for integrated enable, thermal protection, and 1-mm² size - essential for portable RF systems.

FAQ
What is the maximum input voltage rating for TLV70730DQNR?
The absolute maximum input voltage for TLV70730DQNR is 6.0 V, but the recommended operating range is 2.0 V to 5.5 V. Exceeding 5.5 V may cause reliability degradation or permanent damage, even if within absolute max limits. For optimal performance and lifetime, maintain VIN ≤ 5.5 V in all operating conditions.
Does TLV70730DQNR require an external pull-up resistor on the EN pin?
No, TLV70730DQNR does not require an external pull-up on EN. Its enable threshold is VIH = 0.9 V (min) and VIL = 0.4 V (max), allowing direct connection to 1.8 V or higher GPIOs. If EN is unused, tie it directly to IN - this ensures always-on operation without additional components.
Can TLV70730DQNR operate with zero load current?
Yes, TLV70730DQNR regulates its 3.0 V output accurately even with 0 mA load - confirmed in datasheet Electrical Characteristics (DC output accuracy tested at IOUT = 1 mA, but functional down to 0 mA). This makes it ideal for standby rails powering real-time clocks or wake-up comparators.
What is the thermal resistance (RθJA) of TLV70730DQNR in its DQN package?
The junction-to-ambient thermal resistance (RθJA) for TLV70730DQNR in the DQN (X2SON-4) package is 208.1°C/W, measured per JEDEC JESD51-2 with standard 2-layer board layout. Effective thermal performance requires soldering the exposed thermal pad to a minimum 100 mm² copper pour connected to GND.
Is TLV70730DQNR compatible with ceramic capacitors smaller than 1 µF?
Yes - TLV70730DQNR is explicitly characterized for stability with ≥0.1 µF effective output capacitance. This includes 0402/0201 X5R/X7R ceramics derated for bias and temperature. Using 0.1 µF reduces PCB area and cost versus legacy LDOs requiring ≥1 µF, with no compromise in transient response or phase margin.
