Product details
Overview
TLV70730APDQNR from Texas Instruments is a 200-mA, low-quiescent-current (25 μA), low-noise LDO regulator with 3.0-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 blocks in portable electronics.
For engineers reviewing the TLV70730APDQNR datasheet, TLV70730APDQNR pinout, TLV70730APDQNR application, or TLV70730APDQNR equivalent, this page delivers verified electrical specs, thermal behavior, enable control logic, pulldown resistance (120 Ω), and design-critical transient performance data for battery-powered wearable and mobile subsystems.
Technical Context
The TLV70730APDQNR uses a PMOS pass transistor architecture enabling ultra-low dropout voltage (200 mV at 150 mA for 3.0-V output) and reverse-voltage protection via built-in body diode. Its active-high enable pin (VIH = 0.9 V, VIL = 0.4 V) supports direct interfacing with low-voltage GPIOs.
Unlike standard TLV707 variants, the TLV70730APDQNR belongs to the TLV707P family and integrates an internal 120-Ω active pulldown circuit to rapidly discharge the output during shutdown - critical for systems requiring fast rail collapse and sequencing compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±0.5% - ensures stable bias for 3.0-V I/O domains and RF front-end ICs without external feedback. |
| Max Output Current | 200 mA - sufficient to power baseband processors, Bluetooth SoCs, or sensor hubs in compact wearables. |
| Quiescent Current | 25 μA - enables multi-week battery life in always-on sensing applications with minimal standby drain. |
| 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 mV at 150 mA (3.0-V output) - allows operation down to 3.22 V input, extending usable range of single-cell Li-ion batteries. |
| Output Noise | 45 µVRMS (100 Hz–100 kHz) - meets stringent spectral purity requirements for RF receivers and ADC reference supplies. |
| Shutdown Current | 1 μA - reduces system-level leakage during deep sleep modes without external discharge circuitry. |
Pinout & Package
TLV70730APDQNR is housed in a 1.0 mm × 1.0 mm DQN (X2SON-4) package with wettable flank terminations for automated optical inspection (AOI). Thermal pad on underside enhances PCB heat dissipation (RθJB = 159.4°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Regulated output | Delivers clean 3.0-V supply; requires ≥0.1-μF ceramic capacitor to ground for stability - enables use of small 0402/0201 capacitors. |
| GND (Pin 2) | Ground reference | Low-impedance return path; connects to thermal pad for improved thermal performance and EMI reduction. |
| EN (Pin 3) | Enable control | Active-high logic input; asserts regulation when >0.9 V, disables with <0.4 V; supports direct connection to 1.8-V GPIOs. |
| IN (Pin 4) | Input supply | Accepts 2.0–5.5 V input; internal current limit (240–450 mA) protects against short-circuit faults without external components. |
Key Features
| Feature | Design Value |
|---|---|
| 0.1-μF minimum output capacitance | Reduces BOM cost and board area by enabling use of smaller, lower-voltage-rated ceramics (e.g., 6.3-V X5R 0402) without compromising stability. |
| 120-Ω active pulldown | Discharges output within microseconds during shutdown - eliminates need for external pull-down resistors in power-sequenced systems. |
| ±4000-V HBM ESD rating | Meets IEC 61000-4-2 Level 4 requirements - suitable for handheld devices exposed to frequent human contact. |
| Thermal shutdown + current limit | Self-protecting under overload or ambient overtemperature; auto-recovery prevents latch-up in intermittent fault conditions. |
| 0.5% output accuracy | Guarantees consistent voltage across –40°C to +125°C junction temperature - critical for analog sensor signal chains and precision references. |

FAQ
What is the maximum input voltage rating for TLV70730APDQNR?
The absolute maximum input voltage for TLV70730APDQNR is 6.0 V. Operation above this level risks permanent damage. The recommended operating input range is 2.0 V to 5.5 V, ensuring reliable regulation and thermal performance across all load and temperature conditions specified in the datasheet.
Does TLV70730APDQNR require an external pull-down resistor on the output?
No, TLV70730APDQNR does not require an external pull-down resistor because it belongs to the TLV707P family and integrates a 120-Ω active pulldown circuit. This internal resistor automatically discharges the output during shutdown, eliminating the need for discrete components and simplifying layout in space-constrained designs.
Can TLV70730APDQNR operate with a 0.1-μF output capacitor?
Yes, TLV70730APDQNR is explicitly characterized and guaranteed stable with an effective output capacitance of 0.1 μF or greater. This specification applies across temperature and bias conditions, enabling use of compact, cost-effective ceramic capacitors while maintaining phase margin and transient immunity.
What is the typical dropout voltage of TLV70730APDQNR at full load?
The typical dropout voltage of TLV70730APDQNR is 220 mV at 150 mA output current and 250 mV at 200 mA, measured at 3.0-V nominal output. This low dropout enables efficient operation from partially discharged single-cell Li-ion batteries (down to ~3.22 V input) while maintaining regulation.
Is TLV70730APDQNR compatible with 1.8-V GPIO enable signals?
Yes, TLV70730APDQNR is compatible with 1.8-V GPIO enable signals because its EN pin has a VIH threshold of only 0.9 V (min) and VIL of 0.4 V (max). This allows direct connection to modern low-voltage microcontrollers and application processors without level-shifting circuitry.
