Product details
Overview
NCP707BMX310TCG from onsemi is a 200 mA low-dropout (LDO) voltage regulator with fixed 3.1 V output, optimized for battery-powered portable electronics. It delivers ±2% output accuracy over load/line/temperature, achieves 100 mV typical dropout at 200 mA, and features ultra-low 25 µA quiescent current and 22 µVRMS output noise (100 Hz–100 kHz), making it suitable for noise-sensitive RF and sensor power rails in compact handheld devices.
For engineers reviewing the NCP707BMX310TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its XDFN-4 1.0×1.0 mm package, EN-controlled enable/disable functionality, stability with 1 µF ceramic output capacitor, and thermal shutdown/current limit protections for robust operation in space-constrained, low-power systems.
Technical Context
The NCP707BMX310TCG employs a PMOS pass transistor architecture enabling low dropout and inherent reverse-current blocking. Its adaptive ground current circuitry dynamically reduces IQ to 25 µA at no-load while maintaining regulation, critical for extended battery life in always-on subsystems.
It integrates an internal soft-start, active discharge control (not present in 'B' variant), and precision bandgap reference with feedback loop compensation optimized for 1 µF ceramic capacitors. PSRR reaches 70 dB at 1 kHz, and line/load regulation are specified at 400 µV/V and 10 µV/mA respectively - performance validated across −40°C to +125°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.1 V ±2% - ensures stable core/sensor supply without external resistors; validated over full temperature and load range. |
| Max Output Current | 200 mA continuous - supports moderate-power microcontrollers, RF transceivers, or analog front-ends in portable designs. |
| Dropout Voltage | 100 mV typical at 200 mA - enables operation down to VIN = 3.2 V, maximizing usable battery voltage in single-cell Li-ion/Li-poly systems. |
| Quiescent Current | 25 µA typical at no-load - minimizes standby power loss; critical for multi-week battery life in IoT endpoints and wearables. |
| Output Noise | 22 µVRMS (100 Hz–100 kHz) - low enough for powering ADC references, RF synthesizers, or precision op-amps without additional filtering. |
| PSRR | 70 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters, improving signal integrity in mixed-signal SoC power domains. |
| Enable Threshold | VEN_HI = 0.9 V, VEN_LO = 0.4 V - compatible with 1.8 V/3.3 V GPIO logic; built-in hysteresis prevents chatter during slow-rising control signals. |
Pinout & Package
Package: XDFN-4 1.0 mm × 1.0 mm, 0.4 mm pitch, exposed thermal pad (EPAD) - optimized for minimal PCB area and efficient heat dissipation in dense layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Regulated output voltage node | Delivers stable 3.1 V; requires ≥1 µF ceramic capacitor to GND for stability; trace resistance must be minimized to preserve load regulation. |
| 2 - GND | Power ground reference | Primary return path; EPAD must be soldered directly to large GND copper plane for thermal and electrical integrity. |
| 3 - EN | Logic-enable input | Drives high (>0.9 V) to enable regulator; low (<0.4 V) to disable (shutdown current ≤1 µA); internal 180 nA pull-down ensures default-off state. |
| 4 - IN | Input voltage supply | Accepts 1.8–5.5 V; requires ≥1 µF ceramic capacitor close to pin to suppress input ripple and support transient response. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 25 µA at no-load enables >1-year battery life in coin-cell-powered sensors with periodic wake-up cycles. |
| Stable with 1 µF ceramic output cap | Eliminates need for larger, higher-ESR tantalum capacitors - reduces BOM cost and board area in miniaturized designs. |
| ±2% output accuracy over temp/load | Guarantees reliable operation of 3.3 V-tolerant I/O or 3.0 V core logic without margining or calibration. |
| 70 dB PSRR at 1 kHz | Effectively isolates noise-sensitive analog circuits from noisy digital power domains in SoC-based platforms. |
| Thermal shutdown & current limit | Protects against sustained overload or poor heatsinking - maintains reliability without external protection circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3102E/TT | 300 mA rated, 1.6 µA IQ, but only 60 dB PSRR at 1 kHz and 40 µVRMS noise - higher noise and lower rejection than NCP707BMX310TCG. | Suitable for less noise-critical digital rails; not recommended for RF or precision analog where PSRR/noise matter. | Select when ultra-low IQ dominates requirements and noise/PSRR are secondary; verify stability with 1 µF COUT. |
| Torex XC6219B312MR-G | 200 mA, 35 µA IQ, 25 µVRMS noise, 65 dB PSRR - slightly higher IQ and noise, lower PSRR than NCP707BMX310TCG. | Compatible for general-purpose 3.1 V regulation; lacks same level of RF-grade noise suppression. | Choose for cost-sensitive designs where 5 µVRMS noise margin and 5 dB PSRR gap are acceptable. |
Compared with MCP1700T-3102E/TT and XC6219B312MR-G, the NCP707BMX310TCG provides superior noise performance (22 vs. ≥25 µVRMS) and PSRR (70 dB vs. ≤65 dB), making it the preferred choice for RF, sensor, and precision analog applications where signal integrity is non-negotiable.

FAQ
What is the maximum input voltage rating for the NCP707BMX310TCG?
The NCP707BMX310TCG has an absolute maximum input voltage of 6 V. Its recommended operating input voltage range is 1.8 V to 5.5 V. Exceeding 6 V risks permanent damage; operation above 5.5 V is outside specification and may degrade performance or reliability. For 3.1 V output, minimum functional VIN is 3.2 V due to 100 mV typical dropout.
Does the NCP707BMX310TCG include active output discharge?
No, the NCP707BMX310TCG does not include active output discharge. Only NCP707A and NCP707C variants (e.g., NCP707AMX310TCG) feature this function. The 'B' suffix indicates standard enable/disable operation without output pull-down; when disabled, VOUT floats unless externally discharged.
Can the NCP707BMX310TCG operate stably with a 1 µF ceramic output capacitor?
Yes, the NCP707BMX310TCG is explicitly designed and characterized for stability with a minimum 1 µF X5R/X7R ceramic capacitor on the output. This is confirmed in the datasheet's "Stable with a 1 µF Ceramic Output Capacitor" feature and Figure 42 (stability vs. ESR). No additional ESR is required.
What is the thermal shutdown threshold for the NCP707BMX310TCG?
The NCP707BMX310TCG triggers thermal shutdown at a typical junction temperature of 160°C, with hysteresis of 20°C - meaning it resets and resumes regulation when junction temperature falls below approximately 140°C. This protects against catastrophic failure during sustained overload or inadequate PCB copper area.
How does the enable pin behavior differ between NCP707BMX310TCG and other NCP707 variants?
The NCP707BMX310TCG EN pin functions identically to all NCP707 variants: logic-high (>0.9 V) enables regulation; logic-low (<0.4 V) disables output with <1 µA shutdown current. Unlike 'A' and 'C' versions, the 'B' variant lacks active discharge - so EN low leaves VOUT floating rather than actively pulled to GND.
