Product details
Overview
NCP715SQ15T2G from onsemi is a 50 mA ultra-low-quiescent-current LDO linear voltage regulator with fixed 1.5 V output, 2.5–24 V input range, ±2% output accuracy over load/line/temperature, 4.7 µA max ground current, and thermal shutdown/current limiting protection. It delivers stable power to low-power microcontrollers and sensors in battery-powered portable equipment.
For engineers reviewing the NCP715SQ15T2G datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage at 50 mA (≤400 mV), PSRR of 56 dB at 100 kHz, output noise of 75 µVRMS (200 Hz–100 kHz), and SC-70-5 package compatibility with space-constrained PCB layouts.
Technical Context
The NCP715SQ15T2G integrates a bandgap reference, MOSFET driver with current limit, UVLO, and thermal shutdown circuitry. Its internal architecture enables stable regulation across wide input voltages without requiring minimum ESR output capacitors.
It operates across −40°C to +125°C ambient temperature, supports ceramic output capacitors ≥0.47 µF, and maintains ±2% output accuracy under full load (0–50 mA), line (2.5–24 V), and temperature variations - verified per onsemi's characterization and production test protocols.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2% - ensures precise biasing for 1.5 V logic rails and low-voltage analog circuits. |
| Input Voltage Range | 2.5 V to 24 V - supports direct connection to Li-ion batteries, industrial 12 V/24 V rails, and wide-input DC-DC pre-regulators. |
| Max Output Current | 50 mA - sufficient for powering ultra-low-power MCUs, RTCs, and sensor signal chains without derating. |
| Quiescent Current | Max 4.7 µA over full load/temperature - extends battery life in always-on, energy-harvesting, and IoT endpoint applications. |
| Dropout Voltage | 250–400 mV at 50 mA - enables regulation from 1.75 V input, critical for single-cell LiFePO₄ or coin-cell operation. |
| PSRR @ 100 kHz | 56 dB - suppresses high-frequency switching noise from upstream DC-DC converters feeding sensitive analog subsystems. |
| Output Noise | 75 µVRMS (200 Hz–100 kHz) - minimizes jitter and baseline drift in ADC references and precision op-amp stages. |
Pinout & Package
Package: SC-70-5 (SC-88A), 1.25 mm × 1.65 mm × 0.95 mm, Pb-free, moisture-sensitive level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Input supply connection; requires ≥0.1 µF ceramic decoupling capacitor to GND for stability and transient response. |
| 2 | N/C | No connection; may be tied to GND to improve thermal dissipation or left floating - no electrical function. |
| 3 | GND | Power ground reference; must be connected to low-impedance system ground plane for noise immunity and thermal performance. |
| 4 | N/C | No connection; same thermal option as Pin 2 - not electrically active in SC-70-5 configuration. |
| 5 | OUT | Regulated 1.5 V output; requires ≥0.47 µF ceramic capacitor to GND for loop stability and load transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 4.7 µA max over full load/temperature - enables >10-year battery life in 5 µA average-load IoT nodes. |
| Wide input range | 2.5–24 V - eliminates need for intermediate pre-regulation in multi-rail systems with mixed supply sources. |
| Thermal shutdown | 170°C trip with 15°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking conditions. |
| Current limiting | Internal foldback protection - limits peak fault current to <200 mA, safeguarding PCB traces and upstream sources. |
| Capacitor flexibility | Stable with 0.47–10 µF ceramic COUT - removes ESR dependency, simplifies BOM, and reduces cost vs. tantalum alternatives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1502E/TT | 250 mA rated output, 1.6 µA typical IQ, but only 13.2 V max input; SC-70-5 package. | Higher current capability suits higher-power peripherals, but unsuitable for 24 V industrial inputs. | Select when >50 mA load current is required and input stays ≤13.2 V. |
| TNIV5150150R | 150 mA output, 2.5 µA IQ, 2.2–6.0 V input range; SOT-23-5 package. | Narrower input range excludes 12/24 V systems; different pinout (EN, BP, OUT, GND, IN) adds complexity. | Choose for cost-sensitive consumer designs where input is strictly ≤6 V and enable control is needed. |
Compared with MCP1700T-1502E/TT and TNIV5150150R, the NCP715SQ15T2G uniquely balances 24 V input tolerance, 4.7 µA max IQ, and SC-70-5 footprint - making it optimal for long-life, wide-input industrial and medical edge devices where space and input voltage headroom are critical.

FAQ
What is the maximum input voltage rating for the NCP715SQ15T2G?
The NCP715SQ15T2G has an absolute maximum input voltage rating of 24 V, with recommended operating range from 2.5 V to 24 V. Exceeding 24 V risks permanent device damage per onsemi's Absolute Maximum Ratings table. The regulator maintains regulation and specified accuracy across this full range when loaded up to 50 mA.
Does the NCP715SQ15T2G require an external enable pin or power-good indicator?
No, the NCP715SQ15T2G does not include an enable (EN) pin or power-good (PG) output. It operates continuously when valid input voltage is applied. This simplifies design for always-on applications but means system-level control of regulation must be implemented externally - for example, using a series MOSFET switch before the IN pin.
What output capacitor value is required for stable operation of the NCP715SQ15T2G?
The NCP715SQ15T2G is stable with ceramic output capacitors from 0.47 µF to 10 µF - no minimum ESR is required. onsemi recommends X5R or X7R dielectrics for minimal capacitance shift over temperature. A 1.0 µF ceramic capacitor is typical for general-purpose use, while 4.7 µF improves load transient response.
How does thermal shutdown behave in the NCP715SQ15T2G?
The NCP715SQ15T2G triggers thermal shutdown at 170°C junction temperature and remains latched off until junction temperature falls by 15°C (hysteresis). During shutdown, output is disabled and ground current drops to ~1 µA. Recovery is automatic once safe temperature is restored - no external reset is needed.
Can the NCP715SQ15T2G be used with input voltages below 2.5 V?
No - the NCP715SQ15T2G is not characterized or guaranteed to operate below 2.5 V input. Below this threshold, regulation fails, output voltage drops nonlinearly, and ground current increases unpredictably. For sub-2.5 V applications, consider dedicated low-input LDOs such as the NCP161 series.
