Product details
Overview
NCP715MX30TBG from onsemi is a 3.0 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, 250–400 mV dropout at 50 mA, and integrated thermal shutdown and current limiting. It delivers stable power to low-power microcontrollers and sensors in battery-powered portable equipment.
For engineers reviewing the NCP715MX30TBG datasheet, pinout, applications, or equivalent options, key selection criteria include its 4.7 µA max ground current across full load and temperature, 60 dB PSRR at 100 kHz, 135 µVRMS output noise (200 Hz–100 kHz), XDFN6 1.5×1.5 mm package, and compatibility with 0.47 µF ceramic output capacitors.
Technical Context
The NCP715MX30TBG implements a PMOS pass transistor architecture enabling low dropout and ultra-low quiescent current. Its bandgap reference and error amplifier maintain tight regulation under varying line, load, and temperature conditions, while UVLO prevents operation below 2.5 V input.
Protection circuitry includes foldback current limiting that activates before thermal shutdown (triggered at 170°C junction temperature with 15°C hysteresis), ensuring robustness during overload or short-circuit events without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±2% over −40°C to +125°C, 0–50 mA load, and 4.0–24 V input. |
| Quiescent Current | Max 4.7 µA over full load (0–50 mA) and temperature (−40°C to +125°C), enabling multi-year battery life. |
| Dropout Voltage | 250–400 mV at 50 mA output, allowing regulation from 3.25 V input down to 3.0 V output. |
| PSRR | 60 dB at 100 kHz (VIN = 4.0 V, VOUT = 3.0 V), suppressing switching noise from upstream DC-DC converters. |
| Noise | 135 µVRMS (200 Hz–100 kHz), measured with 10 µF COUT, suitable for noise-sensitive analog/RF circuits. |
| Thermal Shutdown | Activates at 170°C junction temperature with 15°C hysteresis, preventing permanent damage during sustained overload. |
| Input Range | 2.5 V to 24 V absolute maximum, supporting wide-input industrial and automotive auxiliary rails. |
Pinout & Package
XDFN6 1.5 × 1.5 mm, 0.5 mm pitch, thermally enhanced Pb-free package (Case 711AE), with exposed thermal pad connected to GND for improved heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Input supply | Accepts 2.5–24 V; requires ≥0.1 µF ceramic decoupling capacitor to GND for stability and transient response. |
| 2 (N/C) | No connection | Internally unconnected; may be tied to GND to improve thermal performance or left floating. |
| 3 (GND) | Power ground | Reference node for regulation and protection circuits; must be low-impedance connection to PCB ground plane. |

| 5 (OUT) | Regulated output | Delivers 3.0 V ±2%; requires ≥0.47 µF ceramic capacitor to GND for loop stability. |
| 6 (N/C) | No connection | Internally unconnected; may be tied to GND to improve thermal performance or left floating. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3002E/TT | 300 mA output, 1.6 µA IQ, SOT-23-3 package, no thermal shutdown | Higher current capability but lacks overtemperature protection; requires external thermal management | Select when >50 mA load current is required and thermal environment is controlled |
| TZL30030002000 | 300 mA, 2.5 µA IQ, X2-DFN1006-3 package, ±1.5% accuracy, no current limit | Smaller footprint and tighter accuracy, but no current limiting or thermal shutdown | Select for space-constrained designs where fault protection is handled at system level |
Compared with MCP1700T-3002E/TT and TZL30030002000, the NCP715MX30TBG provides integrated thermal shutdown and current limiting in a compact XDFN6 package, making it preferable for unattended or safety-critical embedded systems where autonomous fault response is required.

FAQ
What is the maximum input voltage rating for the NCP715MX30TBG?
The NCP715MX30TBG has an absolute maximum input voltage rating of 24 V, with recommended operating range from 4.0 V to 24 V for its 3.0 V output version. Operation below 4.0 V is possible down to 2.5 V but may reduce dropout margin and regulation accuracy per datasheet Section 8.
Does the NCP715MX30TBG require an external capacitor on the output pin?
Yes, the NCP715MX30TBG requires a minimum 0.47 µF ceramic capacitor (X5R or X7R dielectric) between OUT and GND for stability. The device is optimized for low-ESR ceramics and does not require minimum ESR, unlike older LDO architectures.
What is the thermal shutdown threshold and hysteresis of the NCP715MX30TBG?
The NCP715MX30TBG triggers thermal shutdown at 170°C junction temperature and resumes operation after cooling by 15°C (hysteresis), meaning it restarts at approximately 155°C. This behavior is guaranteed by design and characterization, not production-tested per unit.
Can the NCP715MX30TBG be used with a 0.1 µF input capacitor?
Yes - the NCP715MX30TBG datasheet recommends ≥0.1 µF ceramic (X5R/X7R) between IN and GND. This value provides sufficient high-frequency decoupling and limits input trace inductance effects during load transients.
What is the output voltage accuracy specification for the NCP715MX30TBG across temperature and load?
The NCP715MX30TBG guarantees ±2% output voltage accuracy over full operating conditions: −40°C to +125°C junction temperature, 0–50 mA load, and 4.0–24 V input. At 25°C, typical accuracy is ±0.2%, with worst-case deviation bounded by the ±2% limit.
