Product details
Overview
NCP707AMX330TCG from onsemi is a 200 mA low-dropout (LDO) voltage regulator with fixed 3.3 V output, ultra-low quiescent current (25 µA typ.), 22 µVRMS output noise (100 Hz–100 kHz), and 100 mV typical dropout at 200 mA. It features active output discharge (1.2 kΩ), thermal shutdown, current limiting, and stable operation with only 1 µF ceramic output capacitance - ideal for space-constrained, battery-powered portable electronics requiring clean, precise power.
For engineers reviewing the NCP707AMX330TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its 3.3 V fixed output accuracy (±2%), 70 dB PSRR at 1 kHz, XDFN-4 1.0 × 1.0 mm package, EN-controlled enable/disable with active discharge, and compatibility with low-ESR ceramic capacitors without external compensation.
Technical Context
The NCP707AMX330TCG employs a PMOS pass transistor architecture enabling ultra-low dropout and inherent reverse-current blocking. Its adaptive ground current circuitry dynamically reduces IQ to 25 µA at no-load while maintaining regulation across −40°C to +125°C junction temperature.
It integrates an internal soft-start, logic-level enable input (0.4 V low threshold, 0.9 V high threshold), and active output discharge (enabled only in "A" and "C" variants) that pulls VOUT to GND via a 1.2 kΩ resistor when EN < 0.4 V - critical for system-level power sequencing and rail collapse control in portable devices.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.3 V ±2% over load/line/temperature - ensures stable MCU core or RF IC supply without external feedback. |
| Max Output Current | 200 mA continuous - supports single-core microcontrollers, Bluetooth transceivers, or sensor hubs. |
| Dropout Voltage | 100 mV typical at 200 mA - enables operation from 3.4 V input (e.g., single Li-ion cell post-LDO) with full regulation. |
| Quiescent Current | 25 µA typical at no-load - extends battery life in always-on wearable or IoT edge nodes. |
| Output Noise | 22 µVRMS (100 Hz–100 kHz) - meets stringent noise requirements for ADC references or RF synthesizer supplies. |
| PSRR | 70 dB at 1 kHz - suppresses switching noise from upstream DC-DC converters feeding the LDO input. |
| Enable Threshold | EN high = ≥0.9 V, low = ≤0.4 V - compatible with 1.8 V/3.3 V GPIOs without level-shifting. |
Pinout & Package
Package: XDFN-4 (1.0 mm × 1.0 mm, 0.4 mm height), case 711AJ, exposed pad (EPAD) for thermal dissipation. RoHS-compliant, Pb-free, halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Regulated output | Delivers stable 3.3 V; requires ≥1 µF ceramic capacitor to GND for stability and transient response. |
| 2 - GND | Power ground | Reference node for regulation; EPAD must be soldered directly to PCB ground plane for thermal performance. |
| 3 - EN | Enable control input | Logic-high (≥0.9 V) enables regulator; logic-low (≤0.4 V) disables it and activates 1.2 kΩ active discharge path. |
| 4 - IN | Input supply | Accepts 1.8–5.5 V; requires ≥1 µF ceramic capacitor close to pin to suppress input ripple and transients. |
Key Features
| Feature | Design Value |
|---|---|
| Active output discharge | 1.2 kΩ pull-down on OUT when disabled - ensures rapid, controlled rail collapse for safe power sequencing in multi-rail systems. |
| Ultra-low-noise regulation | 22 µVRMS broadband noise - eliminates need for additional LC filtering in sensitive analog/RF power domains. |
| Stable with minimal capacitance | 1 µF ceramic output capacitor sufficient - reduces BOM count and PCB area vs. legacy LDOs requiring ≥10 µF tantalum. |
| Thermal & current protection | Integrated thermal shutdown (160°C) and current limit (~379 mA) - prevents damage during overload or poor heatsinking. |
| Adaptive quiescent current | 25 µA at zero load, rising to 240 µA at 200 mA - optimizes efficiency across dynamic load profiles in battery applications. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-3302E/MB | 300 mA rated, 1.6 µA IQ, no active discharge, SOT-23-5 package | Lacks EN-controlled discharge; higher max current but larger footprint and no thermal shutdown hysteresis | Choose for ultra-low-IQ always-on monitoring where discharge isn't required and 300 mA headroom is needed. |
| Torex XC6206P332MR-G | 200 mA rated, 1 µA IQ, no EN pin, fixed 3.3 V, SOT-23-3 | No enable control or active discharge; simpler interface but no sequencing capability | Choose for cost-sensitive, non-sequenced applications where minimal pin count and lowest possible IQ dominate. |

FAQ
What is the maximum input voltage rating for the NCP707AMX330TCG?
The NCP707AMX330TCG has an absolute maximum input voltage rating of 6 V. Operation is specified over 1.8 V to 5.5 V, with recommended use up to 5.5 V to ensure reliable performance within datasheet limits. Exceeding 6 V may cause permanent damage per Absolute Maximum Ratings.
Does the NCP707AMX330TCG support active output discharge, and how does it function?
Yes, the NCP707AMX330TCG (suffix "A") includes active output discharge. When EN is driven below 0.4 V, an internal 1.2 kΩ resistor connects OUT to GND, rapidly discharging the output capacitor. This feature is confirmed in the datasheet's PIN FUNCTION DESCRIPTION and APPLICATIONS INFORMATION sections for "A" and "C" variants.
What output capacitor value and type are required for stable operation of the NCP707AMX330TCG?
The NCP707AMX330TCG is stable with a minimum 1.0 µF X5R or X7R ceramic capacitor on the output. The datasheet specifies no minimum ESR requirement but caps maximum ESR at 700 mΩ. Tantalum capacitors are not recommended due to high and temperature-dependent ESR.
How does the NCP707AMX330TCG achieve ultra-low quiescent current, and what is its behavior across load conditions?
The NCP707AMX330TCG uses dynamic quiescent current adjustment: IQ is 25 µA at no-load, rises to 105 µA at 2 mA, and reaches 240 µA at 200 mA. This adaptive design minimizes battery drain during sleep modes while maintaining regulation under full load - verified in the ELECTRICAL CHARACTERISTICS table.
Is the NCP707AMX330TCG compatible with 1.8 V GPIOs for enable control?
Yes. The EN pin has a guaranteed low threshold of ≤0.4 V and high threshold of ≥0.9 V, making it fully compatible with 1.8 V logic levels. A 1.8 V GPIO high state (≥1.8 V) exceeds the 0.9 V enable threshold, ensuring reliable turn-on without level-shifting circuitry.
