Product details
Overview
NCP715MX12TBG from onsemi is a 50 mA ultra-low-quiescent-current LDO linear voltage regulator with fixed 1.2 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 serves as a precision low-power supply rail in battery-powered sensor nodes and portable instrumentation.
For engineers reviewing the NCP715MX12TBG datasheet, pinout, applications, or equivalent options, key selection criteria include dropout voltage at 50 mA (≤450 mV), PSRR of 60 dB at 100 kHz, output noise of 65 µVRMS (200 Hz–100 kHz), thermal resistance of 260 °C/W (XDFN6), and compatibility with 0.47 µF ceramic output capacitors.
Technical Context
The NCP715MX12TBG employs a bandgap reference and MOSFET pass element to deliver stable 1.2 V output across wide input (2.5–24 V) and temperature (−40°C to +125°C) ranges. Its internal UVLO prevents operation below 2.5 V, and the integrated thermal shutdown activates at 170°C with 15°C hysteresis.
Ground current remains ultra-low (3.2–5.8 µA) regardless of input voltage up to 24 V or output load (0–50 mA), enabling multi-year battery life in always-on IoT endpoints. The device requires no minimum ESR output capacitor and achieves stability with ≥0.47 µF X5R/X7R ceramics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±2% over full load (0–50 mA), line (2.5–24 V), and temperature (−40°C to +125°C) |
| Quiescent Current | Max 4.7 µA over full load and temperature - enables >10-year battery life in 10 µA sleep-mode systems |
| Dropout Voltage | 260–450 mV at 50 mA - supports regulation down to VIN = 1.46 V for 1.2 V output |
| PSRR | 60 dB at 100 kHz - suppresses switching noise from upstream DC-DC converters |
| Output Noise | 65 µVRMS (200 Hz–100 kHz) - suitable for powering ADC references and RF bias rails |

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 | 300 mA output, 1.8 µA IQ, but only 13.2 V max input and SC-70-5 package (higher RJA = 390 °C/W) | Limited to ≤12 V systems; less robust thermal performance in high-ambient environments | Prefer for cost-sensitive ≤12 V designs where higher output current is needed |
| TLD1117LV12 | 1 A output, 45 µA IQ, 40 V max input, TO-252 package - significantly higher quiescent current | Better for high-current loads but unsuitable for multi-year battery life requirements | Prefer when >100 mA load current or >24 V input (e.g., 36 V industrial) is required |
Compared with MCP1700T-1202E/TT and TLD1117LV12, the NCP715MX12TBG uniquely balances ultra-low IQ (4.7 µA), 24 V input capability, and XDFN6 thermal performance (260 °C/W) - making it optimal for space-constrained, long-life, wide-input battery or industrial systems.

FAQ
What is the maximum input voltage rating for the NCP715MX12TBG?
The NCP715MX12TBG 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 automotive load-dump scenarios, external clamping is advised since the device lacks built-in overvoltage protection beyond this limit.
Does the NCP715MX12TBG require a minimum ESR output capacitor?
No, the NCP715MX12TBG 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 - eliminating the need for costly tantalum or polymer alternatives and simplifying BOM selection.
What is the thermal resistance (RJA) of the NCP715MX12TBG in its XDFN6 package?
The NCP715MX12TBG in the XDFN6 1.5 × 1.5 mm package has a typical junction-to-air thermal resistance (RJA) of 260 °C/W under standard JEDEC test conditions. Actual performance depends on PCB copper area, layer count, and thermal via placement beneath the exposed pad.
How accurate is the output voltage of the NCP715MX12TBG across temperature and load?
The NCP715MX12TBG maintains output voltage within ±2% over −40°C to +125°C ambient temperature, 0–50 mA load, and 2.5–24 V input. At 25°C, the typical output is 1.200 V with min/max of 1.164 V and 1.236 V - sufficient for precision analog circuits without calibration.
Can the NCP715MX12TBG be used with a 0.47 µF output capacitor?
Yes, the NCP715MX12TBG is fully stable with a 0.47 µF X5R or X7R ceramic capacitor on the OUT pin. This value is explicitly validated in the datasheet and enables compact, low-cost designs - especially valuable in space-constrained wearables and sensor modules.
