Product details
Overview
TLV70712APDQNR from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise LDO regulator with 1.2 V fixed output voltage, 0.5% DC accuracy, and 70 dB PSRR at 100 Hz. It operates from 2.0 V to 5.5 V input and delivers stable regulation down to 0.1 µF output capacitance - ideal for powering RF-sensitive subsystems in compact portable electronics.
For engineers reviewing the TLV70712APDQNR datasheet, TLV70712APDQNR pinout, TLV70712APDQNR application, or TLV70712APDQNR equivalent, key selection criteria include dropout voltage at 150 mA (220–270 mV for 1.2 V output), thermal shutdown/overcurrent protection, EN pin logic thresholds (VIH = 0.9 V, VIL = 0.4 V), and X2SON package compatibility with high-density PCB layouts.
Technical Context
The TLV70712APDQNR uses a PMOS pass transistor architecture enabling ultra-low dropout and fast load transient response (<100 µs start-up time). Its internal bandgap reference and error amplifier deliver 0.5% output accuracy across –40°C to +125°C junction temperature and full 0–200 mA load range.
Unlike standard LDOs, it achieves stability with only 0.1 µF effective output capacitance - verified under bias and temperature derating - reducing BOM cost and board area. The device includes active-high enable with integrated pulldown (120 Ω) in TLV707P variants, though TLV70712APDQNR is a TLV707-series part without pulldown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±0.5% - ensures precise core voltage for low-power MCUs and RF ICs without external feedback. |
| Max Output Current | 200 mA - supports moderate-power digital loads such as Bluetooth SoCs or sensor hubs. |
| Quiescent Current | 25 µA - enables multi-week battery life in always-on wearable sensors. |
| PSRR @ 100 Hz | 70 dB - suppresses switching noise from adjacent DC/DC converters feeding shared input rails. |
| Dropout Voltage | 220 mV @ 150 mA - allows operation from single-cell Li-ion (3.0 V min) while maintaining 1.2 V output. |
| Stability Capacitance | 0.1 µF effective - permits use of small, low-cost X5R/X7R ceramics without ESR constraints. |
| Enable Threshold | VIH = 0.9 V, VIL = 0.4 V - compatible with 1.2-V or 1.8-V GPIOs for direct microcontroller control. |
Pinout & Package
TLV70712APDQNR is housed in a 1.0 mm × 1.0 mm DQN (X2SON-4) package with wettable flank terminations for automated optical inspection. Thermal pad on underside enhances power dissipation in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT | Regulated output | Delivers 1.2 V to load; requires ≥0.1 µF ceramic capacitor to GND for stability. |
| GND | Ground reference | Common return path for IN, OUT, and EN; connects to thermal pad for thermal relief. |
| IN | Input supply | Accepts 2.0–5.5 V; requires local 1-µF ceramic decoupling to minimize input ripple. |
| EN | Enable control | Active-high logic input; drives regulator ON above 0.9 V, OFF below 0.4 V; draws ≤0.01 µA. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise regulation | 45 µVRMS output noise (100 Hz–100 kHz) - preserves signal integrity in RF receivers and ADC references. |
| Thermal & current protection | Integrated shutdown triggers at >150°C junction temp and limits output to 240–450 mA - prevents damage during short-circuit events. |
| Ultra-small footprint | 1.0 mm × 1.0 mm X2SON package - saves >60% board area vs. SOT-23, critical for hearables and smart bands. |
| No-load regulation | Maintains 1.2 V ±0.5% accuracy even with zero output current - essential for standby-mode power domains. |
| Wide input range | Operates from 2.0 V to 5.5 V - supports single-cell Li-ion, USB-powered, and multi-rail systems without pre-regulation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPL720F12PDBVR | 200 mA, 1.2 V, 25 µA IQ, but requires minimum 1 µF output capacitor; no EN pin. | Lacks enable control and higher capacitance requirement limit flexibility in dynamic power management designs. | Choose when enable functionality is unnecessary and board layout allows larger output cap. |
| MCP1700T-1202E/TT | 250 mA, 1.2 V, 1.6 µA IQ, SOT-23-5 package; lower IQ but higher dropout (600 mV @ 250 mA). | Higher dropout restricts use with low-voltage batteries; larger SOT-23 footprint increases PCB area. | Prefer for ultra-long-life applications where input voltage margin exceeds 0.6 V. |
Compared with TPL720F12PDBVR and MCP1700T-1202E/TT, TLV70712APDQNR uniquely combines EN control, 0.1 µF stability, and 220 mV dropout in a 1-mm² package - making it optimal for miniaturized, battery-sensitive, and dynamically controlled systems.

FAQ
What is the maximum input voltage rating for TLV70712APDQNR?
The absolute maximum input voltage for TLV70712APDQNR 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 robust design, maintain VIN ≤ 5.5 V under all conditions including transient spikes.
Does TLV70712APDQNR include an active pulldown circuit on the output?
No, TLV70712APDQNR does not include an active pulldown circuit. It belongs to the TLV707 (not TLV707P) family variant. Only TLV707P parts integrate the 120-Ω internal pulldown resistor activated during shutdown. TLV70712APDQNR relies on external discharge paths if rapid output voltage decay is required.
Can TLV70712APDQNR operate stably with a 0.1 µF output capacitor?
Yes, TLV70712APDQNR is explicitly characterized and guaranteed stable with an effective output capacitance of 0.1 µF or greater - including under bias and temperature derating. This enables use of small-footprint, low-cost X5R/X7R ceramics without ESR requirements, unlike many legacy LDOs.
What is the typical dropout voltage of TLV70712APDQNR at 150 mA load?
The typical dropout voltage of TLV70712APDQNR at 150 mA load is 220 mV, with a maximum of 270 mV over temperature and process variation. This value is specified for VOUT = 1.2 V and reflects the minimum VIN–VOUT headroom needed to sustain regulation.
Is TLV70712APDQNR RoHS compliant and lead-free?
Yes, TLV70712APDQNR is RoHS compliant and lead-free. Per Texas Instruments' official packaging information, the DQN (X2SON) package uses lead-free terminal finish and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1), suitable for standard reflow assembly without special handling.
