Product details
Overview
NCP707CMX310TCG 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 ideal for noise-sensitive RF and sensor power rails in compact handheld devices.
For engineers reviewing the NCP707CMX310TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its XDFN-4 1.0×1.0 mm package, active output discharge capability (120 Ω), EN pin logic control, thermal shutdown, and stability with only 1 µF ceramic output capacitance - critical for space-constrained, low-power designs.
Technical Context
The NCP707CMX310TCG integrates a PMOS pass transistor with adaptive ground current control to maintain 25 µA IQ at no-load while scaling with output current. Its internal reference and error amplifier deliver tight regulation across −40°C to +125°C junction temperature, supported by built-in current limiting (379 mA typ.) and thermal shutdown (160°C trip).
It employs an enable-controlled active discharge circuit (RDIS = 120 Ω) that rapidly pulls VOUT to GND upon disable, preventing floating outputs in multi-rail systems. PSRR reaches 70 dB at 1 kHz and remains >55 dB up to 10 kHz, enabled by low-noise bandgap design and optimized loop compensation for 1 µF ceramic capacitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.1 V ±2% - ensures stable core/sensor supply without external feedback components. |
| Max Output Current | 200 mA continuous - supports moderate-power microcontrollers, RF transceivers, or analog front-ends. |
| Dropout Voltage | 100 mV typical at 200 mA - enables operation down to VIN = 3.2 V, extending battery life in single-cell Li-ion/Li-poly systems. |
| Quiescent Current | 25 µA typical at no-load - minimizes standby power loss in always-on IoT sensors or wearables. |
| Output Noise | 22 µVRMS (100 Hz–100 kHz) - meets stringent noise requirements for ADC references and RF LNA biasing. |
| PSRR | 70 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Enable Threshold | VEN_HI = 0.9 V, VEN_LO = 0.4 V - compatible with 1.8 V/3.3 V GPIOs and provides noise immunity via 56 mV hysteresis. |
| Active Discharge | 120 Ω pull-down when disabled - ensures fast, controlled VOUT discharge for sequencing-critical applications. |
Pinout & Package
Package: XDFN-4 (1.0 mm × 1.0 mm, 0.4 mm height), case 711AJ, with exposed thermal pad (EPAD) connected to GND for enhanced heat dissipation. Thermal resistance RJA = 250°C/W on 2 oz FR4 with 100 mm² copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Regulated output | Delivers stable 3.1 V; requires ≥1 µF ceramic capacitor to GND for stability and transient response. |
| 2 - GND | Power ground | Reference node for regulation and thermal path; EPAD must be soldered directly to GND plane. |
| 3 - EN | Enable control input | Logic-high (>0.9 V) enables regulation; logic-low (<0.4 V) disables output and activates 120 Ω discharge. |
| 4 - IN | Input supply | Accepts 1.8–5.5 V; requires ≥1 µF ceramic capacitor to GND near pin for EMI filtering and transient support. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 25 µA at no-load enables >1-year battery life in coin-cell-powered sensors. |
| Low-noise regulation | 22 µVRMS noise avoids corruption of precision analog signals and high-SNR RF receivers. |
| Active output discharge | 120 Ω discharge path ensures rapid, predictable VOUT ramp-down during power sequencing. |
| Stable with minimal capacitance | Guaranteed stability with 1 µF ceramic COUT reduces BOM count and PCB area vs. legacy LDOs requiring 10+ µF. |
| Full protection suite | Thermal shutdown (160°C), current limit (379 mA), and reverse-current awareness prevent field failures. |
| Wide input range | 1.8–5.5 V operation supports direct connection to single-cell Li-ion, USB, or multi-rail intermediate supplies. |

FAQ
What is the output voltage tolerance of the NCP707CMX310TCG over temperature and load?
The NCP707CMX310TCG maintains ±2% output voltage accuracy across −40°C to +125°C junction temperature, full 0–200 mA load range, and input voltage from VOUT + 0.5 V to 5.5 V. This is verified per Electrical Characteristics Table on page 3 of the datasheet, ensuring reliable operation in thermally demanding portable environments without external trimming.
Does the NCP707CMX310TCG support active output discharge, and what is its resistance value?
Yes, the NCP707CMX310TCG includes active output discharge functionality activated when the EN pin is driven below 0.4 V. Its discharge resistance is 120 Ω, as specified in the Electrical Characteristics table (RDIS = 120 Ω for Version C). This enables rapid, controlled VOUT ramp-down essential for power sequencing in multi-voltage-rail systems.
What minimum output capacitance is required for stability with the NCP707CMX310TCG?
The NCP707CMX310TCG is stable with a minimum 1.0 µF ceramic (X5R/X7R) output capacitor, as confirmed in the Applications Information section (page 16). The device remains stable down to 100 nF effective capacitance, but 1.0 µF is the recommended minimum to ensure adequate phase margin and transient response across voltage, temperature, and aging variations.
How does the NCP707CMX310TCG achieve ultra-low quiescent current, and what is its typical value at no-load?
The NCP707CMX310TCG achieves 25 µA typical quiescent current at no-load through adaptive ground current adjustment - dynamically scaling bias currents in the internal reference and error amplifier. This is measured per datasheet conditions (TJ = +25°C, IOUT = 0 mA, VIN = VOUT + 0.5 V), enabling multi-year battery life in always-on sensing applications without sacrificing regulation performance.
Is the NCP707CMX310TCG compatible with 1.8 V GPIO for enable control?
Yes, the NCP707CMX310TCG is fully compatible with 1.8 V GPIOs: its EN pin has a guaranteed turn-on threshold of 0.9 V (min) and turn-off threshold of 0.4 V (max), with 56 mV hysteresis. A 1.8 V logic-high signal exceeds the 0.9 V requirement by >100%, ensuring robust enablement even with voltage droop or noise - confirmed in the Electrical Characteristics table (page 3).
