Product details
Overview
NCP715SN15T1G from onsemi is a 50 mA ultra-low-quiescent-current (4.7 µA max) fixed-output 1.5 V low-dropout linear voltage regulator with 2.5 V to 24 V input range, ±2% output accuracy over load/line/temperature, and integrated thermal shutdown and current limiting. It delivers stable power to battery-powered portable equipment and low-power communication subsystems.
For engineers reviewing the NCP715SN15T1G 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), thermal shutdown at 170°C, and TSOP-5 package compatibility with space-constrained PCB layouts.
Technical Context
The NCP715SN15T1G implements a bandgap-referenced error amplifier driving a PMOS pass transistor, enabling ultra-low ground current across full load and temperature. Its internal UVLO circuit ensures operation only above VIN = 2.5 V for 1.5 V output variants, and the absence of ESR requirements allows stable operation with 0.47 µF ceramic output capacitors.
Thermal protection uses a dedicated junction-sensing circuit with 15°C hysteresis, while current limiting operates in foldback mode to constrain peak output current during overload. The device's PSRR performance degrades above 100 kHz due to internal compensation architecture, and noise is dominated by bandgap reference and error amplifier contributions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2% over −40°C to +125°C, 0–50 mA load, and 3.0–24 V input - ensures precise biasing for 1.5 V logic and analog rails. |
| Quiescent Current | Max 4.7 µA over full load and temperature - enables >10-year battery life in always-on IoT sensors. |
| Dropout Voltage | 250–400 mV at 50 mA - supports regulation from 1.75 V input, critical for single-cell LiFePO₄ or two-cell alkaline systems. |
| PSRR | 56 dB at 100 kHz - suppresses switching noise from adjacent DC-DC converters feeding shared input rails. |
| Output Noise | 75 µVRMS (200 Hz–100 kHz) - meets low-noise requirements for RF front-end biasing and precision ADC references. |
| Thermal Shutdown | Activates at 170°C with 15°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking. |
| Operating Temp | −40°C to +125°C ambient - qualified for automotive cabin and industrial control environments. |

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 output, 1.8 µA IQ, SOT-23-3 package - higher current but no thermal shutdown. | Lacks integrated thermal protection; unsuitable for sustained overload conditions. | Select when higher output current is required and thermal fault coverage is handled externally. |
| TZC1500200100 | 50 mA output, 2.5 µA IQ, SC-70-5 package - lower IQ but only rated to 125°C junction. | Not qualified for extended temperature operation beyond +125°C ambient. | Prefer for ultra-low-power designs where ambient temperature stays ≤85°C. |
Compared with MCP1700T-1502E/TT and TZC1500200100, the NCP715SN15T1G uniquely combines 170°C thermal shutdown, 24 V input capability, and TSOP-5 thermal performance (RJA = 250°C/W) - making it optimal for high-reliability industrial and automotive-adjacent applications where fault resilience and wide input range are mandatory.

FAQ
What is the maximum input voltage rating for the NCP715SN15T1G?
The NCP715SN15T1G has an absolute maximum input voltage rating of 24 V, with recommended operating range from 2.5 V to 24 V for 1.5 V output configuration. Exceeding 24 V risks permanent damage per Absolute Maximum Ratings table. For reliable operation, maintain input within this range and ensure adequate derating under high-temperature conditions.
Does the NCP715SN15T1G require an external output capacitor, and if so, what type and value?
Yes, the NCP715SN15T1G requires a minimum 0.47 µF ceramic capacitor (X5R or X7R dielectric) connected between OUT and GND for stability. Larger values up to 10 µF are supported and improve transient response. Unlike many LDOs, it imposes no minimum ESR requirement, enabling use of low-cost, small-footprint MLCCs without risk of oscillation.
What is the thermal shutdown behavior of the NCP715SN15T1G?
The NCP715SN15T1G 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 irreversible damage during sustained overload or inadequate PCB copper area, and is fully characterized - not just guaranteed by design.
Can the NCP715SN15T1G be used with a 1.2 V input supply?
No, the NCP715SN15T1G cannot regulate from a 1.2 V input. Its minimum operating input voltage is 2.5 V for the 1.5 V output version, as specified in the Electrical Characteristics table. Attempting operation below 2.5 V results in dropout and unregulated output; the internal UVLO also disables regulation below this threshold.
How does the ground current (IGN) of the NCP715SN15T1G vary with load and input voltage?
The NCP715SN15T1G maintains ultra-low ground current: ≤4.2 µA at −40°C to +85°C ambient and 0–50 mA load, rising to 5.8 µA at VIN = 24 V. This near-constant IGN - independent of load - is a key differentiator versus traditional LDOs and directly enables decade-scale battery life in always-on applications.
