Product details
Overview
NCP715SQ12T2G from onsemi is a 50 mA ultra-low-quiescent-current LDO linear voltage regulator delivering a fixed 1.2 V output, operating from 2.5 V to 24 V input, with ±2% output accuracy over load, line, and temperature, 4.7 µA max ground current, and thermal shutdown protection - used in battery-powered portable equipment requiring stable low-voltage bias.
For engineers reviewing the NCP715SQ12T2G datasheet, pinout, applications, or equivalent options, this page provides verified technical context, package-specific pin definitions, real-world use scenarios, and validated alternative options for low-power 1.2 V rail generation in space-constrained industrial and portable systems.
Technical Context
The NCP715SQ12T2G integrates a bandgap reference, error amplifier, MOSFET pass element, and protection circuitry (thermal shutdown at 170°C, current limiting) in a single SC-70-5 (SC-88A) package. Its architecture enables stable regulation down to 2.5 V input while maintaining ultra-low 4.7 µA quiescent current across full load and temperature.
It achieves 60 dB PSRR at 100 kHz and 65 µVRMS output noise (200 Hz–100 kHz) with a 10 µF ceramic output capacitor, supporting clean power delivery for sensitive analog and RF subsystems without requiring minimum ESR output capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±2% over −40°C to +125°C, 0–50 mA load, and 2.5–24 V input - ensures precise core/bias rail for low-voltage MCUs and sensors. |
| Quiescent Current | Max 4.7 µA over full load and temperature - extends battery life in always-on IoT nodes and wearables. |
| Input Voltage Range | 2.5 V to 24 V - supports wide-input industrial supplies and multi-cell battery stacks without external pre-regulation. |
| Dropout Voltage | 260–450 mV at 50 mA (VIN ≥ 3.5 V) - enables regulation from 1.46 V input at 50 mA, critical for deep-discharge battery operation. |
| PSRR | 60 dB at 100 kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Thermal Shutdown | 170°C activation with 15°C hysteresis - prevents permanent damage during sustained overload or poor PCB thermal design. |
| Package | SC-70-5 (SC-88A), 1.6 mm × 1.6 mm × 0.95 mm - enables high-density layout in compact portable PCBs. |
Pinout & Package
SC-70-5 (SC-88A) package: 5-pin surface-mount, Pb-free, moisture-sensitive level 1 (MSL1). Thermal pad not present; thermal dissipation relies on copper area under exposed die pad (no internal thermal pad).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN | Input supply connection; requires ≥0.1 µF ceramic decoupling to GND near pin for stability and transient response. |
| 2 | N/C | No internal connection; may be tied to GND to improve thermal conduction or left floating - no electrical function. |
| 3 | GND | Power ground reference; must be low-impedance path to system ground plane to minimize noise coupling. |
| 4 | N/C | No internal connection; same thermal option as Pin 2 - no signal routing required. |
| 5 | OUT | Regulated 1.2 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 across full temperature and load range - enables >10-year battery life in 10 µA sleep-mode applications. |
| Wide VIN range | 2.5 V to 24 V input - eliminates need for intermediate buck stages when powering from 3.3 V, 5 V, 12 V, or 24 V sources. |
| No minimum ESR requirement | Stable with 0.47–10 µF X5R/X7R ceramics - simplifies BOM and reduces cost vs. tantalum or polymer alternatives. |
| High PSRR at 100 kHz | 60 dB - maintains clean 1.2 V rail even when fed from noisy switcher outputs (e.g., buck converter ripple). |
| Integrated protection | Thermal shutdown (170°C) and current limit - removes need for external fault management circuitry in embedded designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1202E/TT | 1.2 V fixed, 250 mA rating, 1.6 µA IQ, but only 6 V max input voltage. | Suitable for 3.3 V or 5 V input systems; cannot replace NCP715SQ12T2G in 12 V/24 V industrial or automotive inputs. | Select when ultra-low IQ is primary and input stays ≤6 V; verify dropout margin at full load. |
| TLD1112-12-1 | 1.2 V fixed, 150 mA, 5 µA IQ, 40 V max input, AEC-Q100 qualified, but larger SOT-23-5 package. | Designed for automotive environments; includes enable pin and higher voltage tolerance, but requires PCB layout change. | Choose for AEC-Q100-compliant designs needing >24 V headroom or enable control; not drop-in due to pinout and footprint. |
Compared with MCP1700T-1202E/TT and TLD1112-12-1, the NCP715SQ12T2G uniquely balances 24 V input capability, 4.7 µA IQ, SC-70-5 size, and industrial temperature range - making it optimal for space-constrained, wide-input, battery- or bus-powered 1.2 V rails where minimal quiescent draw is critical.

FAQ
What is the maximum input voltage rating for the NCP715SQ12T2G?
The NCP715SQ12T2G has an absolute maximum input voltage of 24 V, with recommended operating range from 2.5 V to 24 V. Exceeding 24 V risks permanent damage per the Absolute Maximum Ratings table. For reliable long-term operation, keep VIN ≤24 V and ensure transient spikes are clamped externally if present.
Does the NCP715SQ12T2G require an external output capacitor, and what value is recommended?
Yes, the NCP715SQ12T2G requires a minimum 0.47 µF ceramic capacitor (X5R or X7R) from OUT to GND for stability. The datasheet confirms stability up to 10 µF with no minimum ESR requirement - enabling use of low-cost, small-footprint MLCCs without series resistors or tantalum alternatives.
What is the thermal shutdown behavior of the NCP715SQ12T2G?
The NCP715SQ12T2G activates thermal shutdown at 170°C junction temperature and remains latched off until junction temperature falls by 15°C (hysteresis), resuming regulation at ~155°C. This protects against sustained overload or inadequate PCB copper area, and is guaranteed by design - no external thermal monitoring needed.
Can the NCP715SQ12T2G be used with a 3.3 V input to generate 1.2 V output?
Yes - with a 3.3 V input, the NCP715SQ12T2G delivers 1.2 V output with typical dropout of ~260 mV at 50 mA, leaving >1.8 V headroom. This ensures stable regulation well within specification, and PSRR remains >60 dB, making it ideal for cleaning noisy 3.3 V rails before analog or RF circuitry.
Is the NCP715SQ12T2G pin-compatible with other variants in the NCP715 family?
Yes - all NCP715 variants (e.g., NCP715SQ15T2G, NCP715SQ33T2G) share identical SC-70-5 pinout and package dimensions. Only the output voltage differs; no PCB redesign is needed when swapping between fixed-output versions in the same package.
