Product details

Overview

NCP707CMX330TCG from onsemi is a 200 mA low-dropout (LDO) linear regulator with fixed 3.3 V output, ultra-low 25 µA quiescent current, 22 µV_RMS output noise (100 Hz–100 kHz), and 100 mV typical dropout at full load-designed for space-constrained, battery-powered portable electronics requiring stable, low-noise power delivery.

For engineers reviewing the NCP707CMX330TCG datasheet, pinout, applications, or equivalent options, key selection criteria include its XDFN-4 1.0×1.0 mm package, active output discharge (120 Ω), ±2% output accuracy over load/line/temperature, and compatibility with 1 µF ceramic output capacitors without ESR requirements.

Technical Context

The NCP707CMX330TCG integrates a PMOS pass transistor with adaptive ground current control to maintain 25 µA IQ at no-load while supporting up to 200 mA output. Its internal soft-start prevents inrush overshoot, and thermal shutdown (160°C) plus current limiting (379 mA typ.) ensure robust operation under fault conditions.

It features an enable input (EN) with 0.4 V low-threshold and 0.9 V high-threshold, hysteresis, and deglitching; when disabled, it draws ≤1 µA shutdown current and activates active output discharge via a 120 Ω internal resistor-exclusive to "C" suffix variants like this part.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 3.3 V ±2% over −40°C to +125°C, load 0–200 mA, line VIN = 3.8–5.5 V
Dropout Voltage	100 mV typical at 200 mA - enables regulation from as low as 3.4 V input
Quiescent Current	25 µA typical at no-load - extends battery life in always-on sensor nodes
Output Noise	22 µV_RMS (100 Hz–100 kHz) - suitable for RF, ADC, and precision analog circuits
PSRR	70 dB at 1 kHz - suppresses switching noise from upstream DC/DC converters
Enable Threshold	VEN_HI = 0.9 V, VEN_LO = 0.4 V - compatible with 1.8 V / 3.3 V logic without level shifters
Active Discharge	120 Ω internal pull-down on OUT when EN < 0.4 V - ensures fast, controlled output discharge

Pinout & Package

XDFN-4 1.0 × 1.0 mm package with exposed thermal pad (EPAD), RoHS-compliant, Pb-free, halogen-free/BFR-free.

Pin/Terminal	Circuit Role	Design Meaning
1 - OUT	Regulated output voltage node	Must connect ≥1 µF ceramic capacitor to GND; supports active discharge during shutdown
2 - GND	Power ground reference	Primary return path; EPAD must be soldered directly to GND plane for thermal performance
3 - EN	Logic-enable control input	Drives high (>0.9 V) to enable; low (<0.4 V) to disable + activate discharge; internal 180 nA pull-down
4 - IN	Input voltage supply	Accepts 1.8–5.5 V; requires ≥1 µF ceramic capacitor close to pin for stability
EPAD	Thermal and electrical ground	Not electrically isolated - must be connected to PCB GND plane for heat dissipation and EMI reduction

Key Features

Feature	Design Value
Ultra-low quiescent current	25 µA typ. at no-load - enables >1-year battery life in coin-cell IoT sensors
Active output discharge	120 Ω internal discharge path - eliminates residual voltage on OUT after shutdown, preventing back-powering
Stability with minimal capacitance	Stable with 1 µF ceramic C_OUT, no ESR requirement - reduces BOM count and board area
High PSRR at audio frequencies	70 dB at 1 kHz - effectively filters ripple from buck converter switching noise
Full protection suite	Thermal shutdown (160°C), current limit (379 mA), and short-circuit safe operation - eliminates need for external fault management

Equivalent & Alternatives

The following parts are listed as comparable options for similar LDO regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MCP1700T-3302E/TT	250 mA rated, 1.6 µA IQ, no active discharge, SOT-23-5 package	Lacks output discharge; higher dropout (600 mV @ 250 mA); larger footprint	Choose for ultra-low-IQ standby where discharge is unnecessary and board space permits SOT-23
Torex XC6210B332MR-G	200 mA rated, 1 µA IQ, 300 mV dropout @ 200 mA, SOT-25 package	No active discharge; lower noise (15 µV_RMS) but higher dropout limits low-VIN use	Prefer when lowest possible IQ dominates design, and input voltage remains ≥3.6 V

Compared with MCP1700T-3302E/TT and XC6210B332MR-G, the NCP707CMX330TCG uniquely combines 25 µA IQ, 100 mV dropout, 22 µV_RMS noise, and integrated 120 Ω active discharge in a 1.0×1.0 mm XDFN - making it optimal for compact, battery-sensitive systems requiring fast, clean power sequencing.

FAQ

What is the maximum input voltage rating for the NCP707CMX330TCG?

The NCP707CMX330TCG has an absolute maximum input voltage of 6 V. Operation is specified over 1.8 V to 5.5 V, with recommended maximum continuous input at 5.5 V. Exceeding 6 V risks permanent damage per the Absolute Maximum Ratings table in the datasheet.

Does the NCP707CMX330TCG require an external output capacitor, and what type is recommended?

Yes, the NCP707CMX330TCG requires a minimum 1 µF ceramic (X5R/X7R) output capacitor connected between OUT and GND. It is stable with capacitors as small as 100 nF, and no ESR requirement exists - but maximum ESR must remain below 700 mΩ. Tantalum capacitors are not recommended due to high/temperature-variable ESR.

How does the active output discharge function work in the NCP707CMX330TCG?

When the EN pin voltage falls below 0.4 V, the NCP707CMX330TCG disables regulation and turns on an internal 120 Ω discharge transistor between OUT and GND. This actively pulls the output voltage to near-zero within milliseconds, preventing back-powering of upstream circuitry and ensuring clean system reset behavior - a feature exclusive to "C" suffix variants like the NCP707CMX330TCG.

What is the output voltage accuracy specification for the NCP707CMX330TCG across temperature and load?

The NCP707CMX330TCG delivers ±2% output voltage accuracy over the full operating range: −40°C to +125°C junction temperature, 0–200 mA load current, and input voltage from (V_OUT + 0.5 V) to 5.5 V. This tolerance is guaranteed by design and characterization, not just typical performance.

Can the NCP707CMX330TCG be used without connecting the EN pin?

Yes - the EN pin has an internal 180 nA pull-down current source, so leaving it unconnected defaults the NCP707CMX330TCG to enabled state. However, for deterministic startup and to avoid noise-induced toggling, onsemi recommends tying EN directly to IN if enable functionality is unused - ensuring reliable turn-on without external components.
