Product details
Overview
NCP715SQ25T2G from onsemi is a 2.5 V fixed-output, 50 mA ultra-low quiescent current LDO linear voltage regulator with 2.5 V to 24 V input range, ±2% output accuracy over load/line/temperature, 260–450 mV dropout at 50 mA, and thermal shutdown/current limiting protection. It delivers stable power for low-power microcontrollers in battery-operated portable equipment.
For engineers reviewing the NCP715SQ25T2G datasheet, pinout, applications, or equivalent options, key selection criteria include ultra-low 4.7 µA ground current across full load and temperature, PSRR of 60 dB at 100 kHz, 115 µVRMS output noise (200 Hz–100 kHz), and compatibility with 0.47 µF ceramic output capacitors in SC-70-5 package.
Technical Context
The NCP715SQ25T2G integrates a bandgap reference, MOSFET driver with current limit, UVLO, and thermal shutdown circuitry. Its internal architecture enables stable regulation down to 2.5 V output while sustaining operation up to 24 V input - critical for industrial sensors powered from wide-range DC rails.
It uses no minimum ESR output capacitor requirement and achieves stability with 0.47 µF–10 µF X5R/X7R ceramics. The SC-70-5 package provides 390°C/W junction-to-air thermal resistance, requiring careful PCB copper area management for continuous 50 mA operation at elevated ambient temperatures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V ±2% over −40°C to +125°C, 0–50 mA load, and 3.5–24 V input - ensures reliable MCU core logic supply under varying battery and line conditions. |
| Quiescent Current | Max 4.7 µA over full load and temperature - extends battery life in always-on IoT endpoints by minimizing standby power loss. |
| Dropout Voltage | 260–450 mV at 50 mA - enables regulation from 2.76 V input, supporting single-cell LiFePO₄ or two-cell alkaline systems. |
| PSRR | 60 dB at 100 kHz - suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Noise | 115 µVRMS (200 Hz–100 kHz) - meets low-noise analog sensor and ADC reference requirements without additional filtering. |
| Protection | Thermal shutdown (170°C trip, 15°C hysteresis) and current limiting - prevents damage during sustained overload or PCB trace faults. |
| Operating Temp | −40°C to +125°C ambient - qualified for automotive cabin, industrial control, and outdoor metering environments. |
Pinout & Package
Package: SC-70-5 (Case 419A), 2.0 mm × 1.25 mm × 0.95 mm, Pb-free, moisture-sensitive level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Main input voltage terminal; requires ≥0.1 µF ceramic decoupling to GND for transient immunity and stability. |
| 2 | N/C | No connection; may be tied to GND to improve thermal dissipation but has no electrical function. |
| 3 | GND | Power ground reference; must connect to low-impedance PCB ground plane to minimize noise coupling and ensure regulation accuracy. |
| 4 | N/C | No connection; same thermal enhancement option as Pin 2; electrically isolated from internal circuitry. |
| 5 | OUT | Regulated 2.5 V output; requires ≥0.47 µF ceramic capacitor to GND for loop stability and load transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 4.7 µA max across full load and temperature - reduces system standby current to sub-µA levels when paired with sleep-mode MCUs. |
| Wide VIN range | 2.5 V to 24 V input - eliminates need for pre-regulation in multi-rail industrial systems and simplifies power tree design. |
| No minimum ESR | Stable with 0.47 µF–10 µF X5R/X7R ceramics - avoids costly tantalum or polymer capacitors and improves reliability. |
| High PSRR | 60 dB at 100 kHz - maintains clean 2.5 V rail even when powered from noisy buck converter outputs. |
| Low noise | 115 µVRMS output noise - supports precision analog front-ends without external LDO post-filtering stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-2502E/TT | 250 mA output, 1.6 µA IQ, 6 V max input, SOT-23-3 package - higher current but narrower input range. | Suitable for higher-load applications where 24 V input is not required and PCB space allows SOT-23-3. | Select when >50 mA load current or <6 V input is guaranteed; avoid if 24 V input or SC-70 footprint is mandatory. |
| TLD1121-33-1 | 300 mA output, 35 µA IQ, AEC-Q100 qualified, TO-252-3 package - automotive-grade but higher quiescent current. | Targeted for automotive body electronics requiring qualification; larger thermal mass but less efficient in ultra-low-power use cases. | Choose only for AEC-Q100-compliant designs where 4.7 µA IQ is not required and TO-252 layout is acceptable. |
Compared with MCP1700T-2502E/TT and TLD1121-33-1, the NCP715SQ25T2G uniquely balances ultra-low 4.7 µA quiescent current, 24 V input capability, and SC-70-5 footprint - making it optimal for space-constrained, wide-input, battery-sensitive applications where neither higher current nor automotive qualification is needed.

FAQ
What is the maximum input voltage rating for the NCP715SQ25T2G?
The NCP715SQ25T2G has an absolute maximum input voltage rating of 24 V. Operation above this voltage risks permanent device damage. For reliable long-term use, the recommended operating input range is 3.5 V to 24 V, as specified in the Electrical Characteristics table for the 2.5 V output version. This wide range supports direct connection to 12 V and 24 V industrial rails without pre-regulation.
Does the NCP715SQ25T2G require a minimum ESR output capacitor?
No, the NCP715SQ25T2G does not require a minimum ESR output capacitor. It is explicitly designed for stability with standard X5R or X7R ceramic capacitors ranging from 0.47 µF to 10 µF. This eliminates the need for specialized low-ESR tantalum or polymer capacitors, reducing BOM cost and improving reliability in temperature-varying environments.
What is the thermal shutdown threshold of the NCP715SQ25T2G?
The NCP715SQ25T2G triggers thermal shutdown at a junction temperature of 170°C, with a hysteresis of 15°C - meaning the device resumes normal operation once the junction cools to approximately 155°C. This behavior is guaranteed by design and characterization, not production-tested per unit, and protects against sustained overload or inadequate PCB heat sinking.
Can the NCP715SQ25T2G be used with a 0.47 µF output capacitor?
Yes, the NCP715SQ25T2G is fully stable with a 0.47 µF ceramic output capacitor, as confirmed in the Applications Information section and Figure 1 schematic. Using this value meets minimum stability requirements while optimizing board space and cost. Larger values (up to 10 µF) further improve load transient response but are not required for basic functionality.
What is the typical output noise performance of the NCP715SQ25T2G?
The NCP715SQ25T2G delivers 115 µVRMS output noise over the 200 Hz to 100 kHz bandwidth, measured at 50 mA load with a 10 µF output capacitor. This low-noise performance is validated in the Electrical Characteristics table on page 7 and supports precision analog circuits such as 12-bit+ ADC references and low-noise op-amp biasing without additional filtering.
