Product details
Overview
TLV70715PDQNT from Texas Instruments is a 200-mA, low-quiescent-current (25 µA), low-noise LDO regulator with 1.5-V fixed output voltage, 0.5% DC accuracy, and 70 dB PSRR at 100 Hz - designed for power-sensitive portable electronics requiring stable low-voltage biasing of RF ICs, sensors, and microcontrollers.
For engineers reviewing the TLV70715PDQNT datasheet, TLV70715PDQNT pinout, TLV70715PDQNT application, or TLV70715PDQNT equivalent, key selection criteria include dropout voltage (≤325 mV at 150 mA), 0.1-µF minimum output capacitance stability, active pulldown (120-Ω) for fast output discharge, thermal/overcurrent protection, and operation across –40°C to +125°C junction temperature.
Technical Context
The TLV70715PDQNT implements a PMOS pass transistor architecture enabling ultra-low dropout and high PSRR without requiring external compensation. Its enable pin (EN) features TTL-compatible thresholds (VIH = 0.9 V, VIL = 0.4 V), supporting direct interfacing with low-voltage GPIOs.
Unlike the standard TLV707 variant, the TLV707P suffix denotes integrated active pulldown circuitry that discharges the output via a 120-Ω internal resistor during shutdown - critical for systems requiring rapid rail collapse and sequencing control in multi-rail portable designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±0.5% - ensures precise biasing for 1.5-V logic, memory I/O, and analog sensor interfaces without external feedback. |
| Max Output Current | 200 mA - supports moderate-power subsystems such as Bluetooth SoCs, display drivers, or multi-sensor hubs. |
| Quiescent Current | 25 µA - enables >1-year battery life in always-on wearable sensors and IoT edge nodes operating from coin cells. |
| Dropout Voltage | 325 mV at 150 mA - allows regulation from 1.825-V input (e.g., single Li-ion cell under load), minimizing wasted headroom. |
| PSRR | 70 dB at 100 Hz - suppresses switching noise from adjacent DC/DC converters feeding shared input rails in compact PCB layouts. |
| Output Noise | 45 µVRMS (100 Hz–100 kHz) - meets low-noise requirements for ADC reference supplies and RF front-end biasing. |
| Shutdown Current | 1 µA - reduces standby leakage in sleep-mode applications where EN is controlled by system MCU. |
Pinout & Package
TLV70715PDQNT uses the DQN (X2SON) 4-pin package: 1.00 mm × 1.00 mm footprint with bottom thermal pad, optimized for space-constrained portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Regulated output | Delivers stable 1.5-V supply; requires ≥0.1-µF ceramic capacitor to ground for stability - enables use of small 0201/0402 capacitors. |
| GND (Pin 2) | Ground reference | Common return path for input/output currents and internal bandgap; connects to thermal pad for enhanced heat dissipation. |
| EN (Pin 3) | Enable control | Active-high logic input; asserts regulator when ≥0.9 V applied - compatible with 1.8-V GPIOs; pulls output low via 120-Ω resistor when <0.4 V. |
| IN (Pin 4) | Input supply | Accepts 2.0–5.5 V input; internal PMOS pass element minimizes dropout; requires local 1-µF ceramic bypass near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Stable with 0.1-µF COUT | Reduces BOM cost and board area by enabling use of smaller, lower-voltage-rated ceramic capacitors without compromising stability. |
| Active pulldown (120 Ω) | Ensures rapid, controlled discharge of 1.5-V rail during shutdown - prevents floating outputs and simplifies power sequencing in multi-voltage systems. |
| Thermal shutdown & current limit | Protects against sustained overloads or short circuits; cycles safely between current limit and thermal shutdown until fault clears. |
| Low-noise 45 µVRMS | Eliminates need for post-LDO filtering in noise-sensitive signal chains - suitable for precision ADC references and RF synthesizer VCO supplies. |
| –40°C to +125°C operation | Validated performance across industrial and automotive cabin temperature ranges - supports deployment in harsh-environment wearables and telematics modules. |

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 (40 µA), no pulldown, TO-252 package (6.6 × 7.6 mm) | Targeted at automotive body electronics; lacks 1.5-V option and active pulldown | Select only if higher current and AEC-Q100 qualification are required; not suitable for space-constrained portable designs. |
| AP7361D-15SG-7 | 300-mA output, 1.5-V fixed, 50 µA IQ, SOT-23-5 package, no pulldown | General-purpose LDO; larger footprint and higher quiescent current than TLV70715PDQNT | Choose when board layout allows SOT-23 and pulldown functionality is unnecessary; avoid for ultra-low-power or fast-sequencing systems. |
Compared with TLS850F0TESK and AP7361D-15SG-7, TLV70715PDQNT delivers superior space efficiency (1-mm² X2SON), lowest quiescent current (25 µA), and unique active pulldown - making it optimal for miniaturized, battery-critical portable devices requiring precise 1.5-V regulation and controlled shutdown behavior.

FAQ
What is the minimum output capacitance required for stable operation of TLV70715PDQNT?
The TLV70715PDQNT is stable with an effective output capacitance of just 0.1 µF - significantly lower than most LDOs. This allows use of small-case ceramic capacitors (e.g., 0201 or 0402) even after voltage and temperature derating. A 1-µF ceramic capacitor is recommended for optimal transient performance, but 0.1 µF is the absolute minimum for stability per TI's datasheet specifications.
Does TLV70715PDQNT include active pulldown functionality, and how does it behave?
Yes, TLV70715PDQNT includes active pulldown: when the EN pin is driven below 0.4 V, an internal 120-Ω resistor connects OUT to GND, rapidly discharging the output capacitor. This feature is exclusive to the TLV707P variant and enables controlled rail collapse for power sequencing - critical in multi-rail portable systems where uncontrolled floating voltages could cause latch-up or data corruption.
What is the maximum input voltage rating for TLV70715PDQNT, and what happens above this limit?
The absolute maximum input voltage for TLV70715PDQNT is 6.0 V. Exceeding this voltage risks permanent damage, as specified in the Absolute Maximum Ratings table. Operation above 5.5 V (the recommended maximum) may degrade PSRR, increase dropout, or trigger thermal shutdown prematurely - all parameters are characterized and guaranteed only within the 2.0–5.5 V recommended operating range.
How does TLV70715PDQNT achieve 0.5% output voltage accuracy, and is it load- or temperature-dependent?
TLV70715PDQNT achieves 0.5% typical DC accuracy via a precision internal bandgap reference and trimmed error amplifier. The datasheet specifies ±1.5% total accuracy over –40°C to +85°C junction temperature and full load range (0–200 mA), including initial tolerance, line regulation (≤5 mV), and load regulation (≤20 mV). At 25°C and 1 mA load, accuracy is ±0.5% - making it suitable for precision biasing of ADC references and memory I/O.
Can TLV70715PDQNT be used without an enable signal, and what is the default state?
Yes - TLV70715PDQNT can operate without external enable control by connecting the EN pin directly to the IN pin. In this configuration, the device remains permanently enabled as long as input voltage is present and within specification. No pull-up resistor is needed, since the EN threshold (0.9 V min) is reliably exceeded by any valid IN voltage (≥2.0 V).
