Product details
Overview
NCP707BMX250TCG from onsemi is a 200 mA low-dropout (LDO) voltage regulator with fixed 2.5 V output, ultra-low 25 µA quiescent current, 22 µVRMS output noise (100 Hz–100 kHz), and 100 mV typical dropout at 200 mA. It operates from 1.8 V to 5.5 V input and delivers ±2% output accuracy over load, line, and temperature - ideal for noise-sensitive, space-constrained battery-powered systems such as GPS modules and portable medical devices.
For engineers reviewing the NCP707BMX250TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its XDFN-4 1.0×1.0 mm package, enable-controlled ON/OFF functionality, thermal shutdown and current limit protection, stability with 1 µF ceramic output capacitor, and suitability for low-noise analog rails in portable electronics.
Technical Context
The NCP707BMX250TCG uses a PMOS pass transistor architecture enabling true reverse-current blocking and very low dropout. Its adaptive quiescent current circuitry dynamically reduces ground current to 25 µA at no-load while scaling up to 240 µA at full 200 mA load - optimizing battery life across operating conditions.
It integrates an internal soft-start, active enable logic with 0.4 V low-threshold and 0.9 V high-threshold, and robust protection including thermal shutdown (160°C trip, 20°C hysteresis) and output short-circuit limiting (~390 mA). The device achieves 70 dB PSRR at 1 kHz and maintains stability without ESR requirements on the output capacitor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5 V ±2% over −40°C to +125°C, load 0–200 mA, line 3.0–5.5 V - ensures stable rail for precision analog or RF circuitry. |
| Quiescent Current | 25 µA typical at no-load - extends battery runtime in always-on sensor nodes and standby modes. |
| Dropout Voltage | 100 mV typical at 200 mA - enables regulation from 2.6 V input, critical for single-cell Li-ion or Li-poly systems. |
| Output Noise | 22 µVRMS (100 Hz–100 kHz) - meets stringent noise requirements for ADC references, PLLs, and RF front-ends. |
| PSRR | 70 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input. |
| Enable Threshold | 0.4 V (low) / 0.9 V (high) - compatible with standard GPIOs and supports clean power sequencing. |
| Thermal Shutdown | 160°C trip with 20°C hysteresis - prevents permanent damage during sustained overload or poor PCB heat sinking. |
Pinout & Package
Package: XDFN-4 1.0 mm × 1.0 mm, 0.4 mm height, exposed thermal pad (EPAD) - optimized for minimal PCB area and efficient heat transfer to ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Regulated output voltage node | Connect ≥1 µF ceramic capacitor directly to GND; trace resistance must be minimized to preserve ±2% accuracy at full load. |
| 2 - GND | Power supply reference and return path | Must connect EPAD directly to this pin and to large ground copper area for thermal and noise performance. |
| 3 - EN | Logic-enable control input | Drive >0.9 V to enable; <0.4 V to disable (shutdown current ≤1 µA); internal 180 nA pull-down ensures default-off state. |
| 4 - IN | Input voltage supply node | Requires ≥1 µF ceramic capacitor close to pin; reverse-current flow possible if VOUT > VIN - external protection may be needed. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ operation | 25 µA quiescent current at zero load enables multi-year battery life in IoT endpoints and wearables. |
| Low-noise regulation | 22 µVRMS noise floor supports high-resolution SAR ADCs and low-phase-noise clock buffers without added filtering. |
| Stable with 1 µF ceramic COUT | No ESR requirement simplifies BOM and layout; eliminates need for tantalum or polymer capacitors. |
| Integrated protections | Current limit (~379 mA), thermal shutdown (160°C), and safe disable state prevent field failures in unattended deployments. |
| Small-footprint packaging | XDFN-4 1.0×1.0 mm saves >60% board area vs. SOT-23-5 - critical for compact handheld and hearing aid designs. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-2502E/TT | 250 mA rated, 1.6 µA IQ, 300 mV dropout at 250 mA, SOT-23-5 package | Larger dropout and higher minimum input voltage (2.7 V) limit use in sub-3 V battery systems | Select when ultra-low IQ dominates over noise and footprint; verify PSRR and transient response for analog loads. |
| TPL7407LPWPR | 200 mA rated, 25 µA IQ, 175 mV dropout at 200 mA, 6-pin WSON package | Higher dropout and no integrated thermal shutdown - requires external thermal monitoring | Choose only if board space allows larger WSON and system-level thermal management is already implemented. |
Compared with MCP1700T-2502E/TT and TPL7407LPWPR, the NCP707BMX250TCG delivers superior noise performance (22 µVRMS vs. >40 µVRMS), lower dropout (100 mV vs. ≥175 mV), and integrated thermal protection - making it the preferred choice for high-fidelity analog and compact battery-powered designs where rail cleanliness and reliability are non-negotiable.

FAQ
What is the maximum input voltage rating for the NCP707BMX250TCG?
The NCP707BMX250TCG has an absolute maximum input voltage rating of 6 V. Operation above 5.5 V is not recommended per datasheet specifications, and sustained exposure beyond 6 V may cause permanent damage. For reliable operation, maintain input within 1.8 V to 5.5 V, with headroom ≥100 mV above the 2.5 V output to ensure regulation.
Does the NCP707BMX250TCG support active output discharge?
No, the NCP707BMX250TCG does not include active output discharge. That feature is only present in "A" and "C" suffix variants (e.g., NCP707AMX250TCG and NCP707CMX250TCG). The "B" suffix indicates standard enable functionality without discharge - when disabled, the output floats and discharges only through external load or parasitic paths.
Can the NCP707BMX250TCG operate stably with a 100 nF output capacitor?
Yes - the NCP707BMX250TCG is specified to remain stable with a minimum effective output capacitance of 100 nF. However, the datasheet recommends ≥1 µF ceramic for guaranteed margin against capacitance loss due to DC bias, temperature, and tolerance. Using 100 nF may reduce transient response and PSRR at high frequencies.
What is the typical ground current of the NCP707BMX250TCG at 200 mA load?
The typical ground current (IGND) of the NCP707BMX250TCG at 200 mA output load is 240 µA. This value reflects total current drawn from the IN pin excluding load current - critical for calculating total system power consumption and verifying thermal limits under full load.
Is the NCP707BMX250TCG RoHS compliant and lead-free?
Yes, the NCP707BMX250TCG is Pb-free, halogen-free/BFR-free, and fully RoHS compliant per EU Directive 2011/65/EU. The XDFN-4 package uses matte tin (Sn) lead finish, and the device meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) for unlimited floor life at ≤30°C/85% RH.
