Product details
Overview
TLV70730PDQNT from Texas Instruments is a 200-mA, low-noise, low-quiescent-current (25 µA) LDO regulator with 3.0 V fixed output, 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 - enabling compact, cost-effective power supply design for battery-powered RF subsystems.
For engineers reviewing the TLV70730PDQNT datasheet, TLV70730PDQNT pinout, TLV70730PDQNT application, or TLV70730PDQNT equivalent, key selection criteria include dropout voltage (≤220 mV @ 150 mA), active pulldown resistance (120 Ω), shutdown current (1 µA), thermal/overcurrent protection, and X2SON-4 package compatibility with space-constrained portable layouts.
Technical Context
The TLV70730PDQNT implements a PMOS pass transistor architecture with integrated bandgap reference, enabling ultra-low quiescent current and fast line/load transient response. Its enable logic requires only 0.9 V high-level threshold, supporting direct interfacing with low-voltage GPIOs.
Unlike standard TLV707 variants, the "P" suffix denotes an active pulldown circuit that discharges the output via a 120-Ω internal resistor during shutdown - critical for preventing floating rail conditions in multi-rail systems and ensuring controlled power sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±0.5% - ensures precise biasing for 3.0-V logic, RF front-ends, and analog sensors without external feedback. |
| Max Output Current | 200 mA - supports moderate-power peripherals like BLE radios, display drivers, or sensor signal chains. |
| Quiescent Current | 25 µA - extends battery life in always-on wearable or IoT edge nodes with infrequent wake cycles. |
| PSRR @ 100 Hz | 70 dB - suppresses switching noise from upstream DC/DC converters, preserving signal integrity in RF receivers. |
| Dropout Voltage | 220 mV @ 150 mA - enables operation from single-cell Li-ion (3.0 V min) or two-cell alkaline (3.0 V typical) with margin. |
| Stability Capacitance | 0.1 µF minimum effective COUT - allows use of small-footprint 0402/0201 ceramic capacitors, reducing PCB area by >50% vs legacy LDOs. |
| Shutdown Current | 1 µA - minimizes leakage in deep-sleep modes, critical for multi-year battery operation in remote sensors. |
Pinout & Package
TLV70730PDQNT uses the DQN (X2SON-4) package: 1.0 mm × 1.0 mm, 4-pin, bottom-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 voltage node | Delivers stable 3.0 V; requires ≥0.1 µF ceramic capacitor to GND for stability; connects directly to load VCC rails. |
| GND (Pin 2) | Power ground reference | Common return path for IN, OUT, and EN; must be connected to low-impedance system ground plane for noise immunity. |
| EN (Pin 3) | Active-high enable control | Drives >0.9 V to enable; <0.4 V to enter shutdown; compatible with 1.8-V GPIOs; internally pulled down when floating. |
| IN (Pin 4) | Unregulated input supply | Accepts 2.0–5.5 V; requires local 1-µF ceramic bypass capacitor to GND near pin for transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Active pulldown circuit | 120-Ω internal discharge path ensures rapid, controlled VOUT ramp-down during shutdown - prevents latch-up in downstream logic. |
| Ultra-low noise | 45 µVRMS (100 Hz–100 kHz) - avoids interference in sensitive analog/RF stages such as ADC references or LNA bias networks. |
| Thermal + overcurrent protection | Auto-recovery shutdown triggers at junction temperature >150°C or output short-circuit - protects IC and PCB during fault conditions. |
| Wide input range | 2.0 V to 5.5 V operation - supports single Li-ion, dual alkaline, USB VBUS, or post-regulated DC/DC outputs without redesign. |
| Low-ESR capacitor tolerance | Stable with ≥0.1 µF effective output capacitance - accommodates high-bias-voltage derating of small-size X5R/X7R ceramics (e.g., 0402 1.0 µF). |
Applications
| Wearable Health Monitor | Bluetooth LE Peripheral |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLS850F0TESK | 500-mA output, higher IQ (45 µA), no pulldown, TO-252-5 package | Designed for automotive body electronics; AEC-Q100 qualified; larger thermal footprint | Choose for higher current or automotive qualification; avoid if board space or pulldown is required. |
| MCP1700T-3002E/TT | 250-mA output, 1.6 µA IQ, no EN pin, SOT-23-3 package | Fixed-enable only; lacks shutdown control; lower noise (25 µVRMS) but no pulldown | Choose for ultra-low-IQ always-on rails; avoid when GPIO-controlled enable or active discharge is needed. |
Compared with TLS850F0TESK and MCP1700T-3002E/TT, TLV70730PDQNT uniquely balances 200-mA capability, 25-µA IQ, 120-Ω pulldown, and 1.0-mm² X2SON packaging - making it optimal for space- and battery-limited portable RF systems where controlled power sequencing is mandatory.

FAQ
What is the maximum input voltage rating for TLV70730PDQNT?
The absolute maximum input voltage for TLV70730PDQNT is 6.0 V. However, the recommended operating range is 2.0 V to 5.5 V. Exceeding 5.5 V may compromise reliability or trigger overvoltage protection not specified in the datasheet. Always maintain VIN within this range for guaranteed performance and longevity of TLV70730PDQNT.
Does TLV70730PDQNT require an external pull-up resistor on the EN pin?
No - TLV70730PDQNT features an internal pull-down on the EN pin, so it defaults to shutdown when left unconnected. An external pull-up is only needed if active-high enable is required without relying on a host GPIO. This simplifies design and reduces BOM count for TLV70730PDQNT implementations.
Can TLV70730PDQNT operate with a 0.1 µF output capacitor?
Yes - TLV70730PDQNT is explicitly characterized and guaranteed stable with an effective output capacitance of 0.1 µF or greater. This includes derated values under bias and temperature, enabling use of compact 0402 X5R ceramics. Confirm effective COUT ≥ 0.1 µF at operating voltage and temperature for TLV70730PDQNT.
What is the purpose of the 120-Ω pulldown resistor in TLV70730PDQNT?
The 120-Ω internal pulldown in TLV70730PDQNT actively discharges the OUT pin during shutdown, preventing floating voltages that could cause unintended behavior in downstream logic or analog circuits. This eliminates the need for external discharge components and ensures deterministic power sequencing - a key differentiator of TLV70730PDQNT over non-P variants.
Is TLV70730PDQNT suitable for automotive applications?
TLV70730PDQNT is not AEC-Q100 qualified and is rated for –40°C to +125°C operating junction temperature - sufficient for many under-hood or cabin-adjacent industrial applications, but not certified for automotive safety-critical systems. For automotive use, consider TI's TLS850F0TESK or other AEC-Q100 LDOs instead of TLV70730PDQNT.
