Product details
Overview
NCP707AMX180TCG from onsemi is a 200 mA low-dropout (LDO) linear regulator with fixed 1.8 V output, ultra-low 25 µA quiescent current, 22 µVRMS 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 NCP707AMX180TCG datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, XDFN4 package layout, active output discharge capability, thermal shutdown behavior, and real-world selection guidance for noise-sensitive, low-power embedded systems.
Technical Context
The NCP707AMX180TCG integrates a PMOS pass transistor with adaptive ground current control to maintain 25 µA IQ across input voltages from 1.8 V to 5.5 V. Its internal soft-start prevents output overshoot during enable, while the EN pin provides logic-level ON/OFF control with 0.9 V high-threshold and 0.4 V low-threshold switching.
This variant includes active output discharge (RDIS = 1.2 kΩ), pulling VOUT to GND when disabled - a feature absent in non-A/C suffix versions. It achieves ±2% output accuracy over −40°C to +125°C and maintains stability with only 1 µF ceramic output capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.8 V ±2% - ensures precise core voltage for 1.8 V I/O domains and low-voltage microcontrollers. |
| Max Output Current | 200 mA continuous - supports moderate-power RF modules, sensors, and baseband ICs without external heatsinking. |
| Quiescent Current | 25 µA typical at no-load - extends battery life in always-on wearable and IoT edge nodes. |
| Dropout Voltage | 100 mV typical at 200 mA - enables operation down to VIN = 1.9 V, 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, RF synthesizers, and audio codecs. |
| PSRR | 70 dB at 1 kHz - suppresses ripple from noisy switchers or shared power rails feeding mixed-signal subsystems. |
| Enable Threshold | VEN_HI = 0.9 V, VEN_LO = 0.4 V - compatible with 1.8 V GPIOs and provides noise immunity via 56 mV hysteresis. |
| Active Discharge | RDIS = 1.2 kΩ - discharges output within microseconds after disable, preventing hold-up voltage in multi-rail sequencing. |
Pinout & Package
XDFN4 1.0 × 1.0 mm package with 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 | Delivers stable 1.8 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 1.2 kΩ discharge path. |
| 4 - IN | Input supply | Accepts 1.8–5.5 V; requires ≥1 µF ceramic capacitor close to pin to suppress high-frequency noise and transients. |
| EPAD | Thermal & electrical ground | Must be connected to large GND copper area; primary path for heat dissipation (RJA = 250 °C/W). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 25 µA at no-load enables >10-year battery life in coin-cell-powered sensors and BLE beacons. |
| Active output discharge | 1.2 kΩ internal discharge path ensures rapid VOUT decay (<100 µs for 1 µF), critical for safe power-down sequencing. |
| Stability with small capacitors | Guaranteed stable with 1 µF ceramic COUT - eliminates need for larger, costly tantalum or polymer caps. |
| High PSRR at 1 kHz | 70 dB rejection of switching noise from upstream DC-DC converters improves signal integrity in mixed-signal SoCs. |
| Robust protection suite | Integrated thermal shutdown (160°C), current limiting (~379 mA), and short-circuit tolerance ensure field reliability. |
| Wide input voltage range | 1.8–5.5 V operation supports direct connection to single-cell Li-ion, USB, or legacy 3.3/5 V rails. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1802E/TT | 250 mA max output, 1.8 V fixed, 1.8–6.0 V input, 2 µA IQ - lower quiescent current but no active discharge. | Lacks active output discharge; suitable where fast VOUT decay is not required. | Select when ultra-low IQ dominates design priority and sequencing is simple. |
| Torex XC6206P182MR-G | 200 mA max, 1.8 V fixed, 2.0–6.0 V input, 1 µA IQ, no EN pin - simpler control but no enable or discharge. | No enable function; requires external MOSFET for power gating; no discharge path. | Choose for cost-sensitive, always-on applications where EN and discharge are unnecessary. |

FAQ
What is the maximum input voltage rating for the NCP707AMX180TCG?
The NCP707AMX180TCG has an absolute maximum input voltage of 6 V, with recommended operating range from 1.8 V to 5.5 V. Exceeding 6 V risks permanent damage per the Absolute Maximum Ratings table. For reliable operation, VIN should remain ≤5.5 V under all conditions including ripple and transients.
Does the NCP707AMX180TCG require an external pull-up resistor on the EN pin?
No - the NCP707AMX180TCG includes an internal pull-down current source (180 nA typical) on the EN pin, ensuring default-disable behavior when left floating. A pull-up is only needed if active-high logic control is required; tying EN directly to IN is acceptable if enable functionality is unused.
Can the NCP707AMX180TCG operate stably with a 100 nF output capacitor?
Yes - the NCP707AMX180TCG is specified to remain stable with a minimum effective output capacitance of 100 nF. However, 1 µF is recommended for guaranteed phase margin, improved load transient response, and margin against DC bias and temperature-induced capacitance loss in ceramic capacitors.
What is the purpose of the exposed pad (EPAD) on the NCP707AMX180TCG package?
The EPAD serves dual roles: (1) thermal conduction - it must be soldered to a large GND copper plane to achieve the rated 250 °C/W junction-to-air thermal resistance; (2) electrical grounding - it connects internally to the GND terminal and improves noise immunity and EMI performance.
How does the active output discharge function behave in the NCP707AMX180TCG?
When the EN pin voltage drops below 0.4 V, the NCP707AMX180TCG disables regulation and activates an internal 1.2 kΩ discharge path between OUT and GND. This pulls VOUT to near-zero within microseconds (e.g., ~10 µs for 1 µF load), eliminating residual voltage that could interfere with downstream power sequencing or cause latch-up.
